Tree plantations displacing native forests: the nature and drivers of apparent forest recovery on former croplands in Southwestern China from 2000 to 2015

Biological Conservation, Vol. 222 (June 2018), pp. 113-124,


China is credited with undertaking some of the world's most ambitious policies to protect and restore forests, which could serve as a role model for other countries. However, the actual environmental consequences of these policies are poorly known. Here, we combine remote-sensing analysis with household interviews to assess the nature and drivers of land-cover change in southwestern China between 2000–2015, after China's major forest protection and reforestation policies came into effect. We found that while the region's gross tree cover grew ...


World’s carbon emissions set to spike by 2% in 2017

Nature, Vol. 551, No. 7680. (13 November 2017),


Increased coal use in China appears to be driving the first increase in global greenhouse-gas output since 2014. [Excerpt] [...] Humanity’s carbon emissions are likely to surge by 2% in 2017, driven mainly by increased coal consumption in China, scientists reported on 13 November. The unexpected rise would end a three-year period in which emissions have remained flat despite a growing global economy. [...] Several factors caused the world’s CO2 emissions to level out from 2014 to 2016, including an economic slowdown ...


Spatial patterns and drivers of fire occurrence and its future trend under climate change in a boreal forest of Northeast China

Global Change Biology, Vol. 18, No. 6. (June 2012), pp. 2041-2056,


Understanding the spatial patterns of fire occurrence and its response to climate change is vital to fire risk mitigation and vegetation management. Focusing on boreal forests in Northeast China, we used spatial point pattern analysis to model fire occurrence reported from 1965 to 2009. Our objectives were to quantitate the relative importance of biotic, abiotic, and human influences on patterns of fire occurrence and to map the spatial distribution of fire occurrence density (number of fires occurring over a given area ...


Strengthening protected areas for biodiversity and ecosystem services in China

Proceedings of the National Academy of Sciences, Vol. 114, No. 7. (14 February 2017), pp. 1601-1606,


[Significance] Following severe environmental degradation from rapid economic development, China is now advancing policies to secure biodiversity and ecosystem services. We report the first nationwide assessment, showing that protected areas (PAs) are not well delineated to protect either biodiversity or key ecosystem services. This serious deficiency exists in many countries. We propose creating a national park system in China to help guide development along a path of green growth, improving the well-being of both people and nature. This involves establishing new, strictly ...

Science, Vol. 333, No. 6042. (2011), pp. 581-587,


On 28 April 2011, China's state statistics bureau released its first report on the country's 2010 population census. The report states that the total population of mainland China reached 1.3397 billion in 2010, with an annual average population growth rate of 0.57% during the previous 10 years. The share of the total population aged 0 to 14 declined from 22.9% in 2000 to 16.6% in 2010, whereas the proportion aged 65 and above grew from 7.0% to 8.9% during the same ...


Inverse relations between amounts of air pollution and orographic precipitation

Science, Vol. 315, No. 5817. (2007), pp. 1396-1398,


Particulate air pollution has been suggested as the cause of the recently observed decreasing trends of 10 to 25% in the ratio between hilly and upwind lowland precipitation, downwind of urban and industrial areas. We quantified the dependence of this ratio of the orographic-precipitation enhancement factor on the amounts of aerosols composed mostly of pollution in the free troposphere, based on measurements at Mt. Hua near Xi'an, in central China. The hilly precipitation can be decreased by 30 to 50% during ...


Changes of Holdridge life zone diversity in all of China over half a century

Ecological Modelling, Vol. 144, No. 2-3. (October 2001), pp. 153-162,


The research results show that diversity at the scale of Holdridge life zone observation has had a decreasing trend since the 1950s, and the ecological environment has become considerably unstable in China. The phenomena of unstable environment include continuous expansion of calamity areas since the 1950s, the seldom-seen flood that occurred in the summer of 1998 and the seldom-seen sand and dust weather that occurred in the spring of 2000. Both human activities and climate change are driving forces of the ...


Mirid Bug Outbreaks in Multiple Crops Correlated with Wide-Scale Adoption of Bt Cotton in China

Science, Vol. 328, No. 5982. (28 May 2010), pp. 1151-1154,


Long-term ecological effects of transgenic Bacillus thuringiensis (Bt) crops on nontarget pests have received limited attention, more so in diverse small holder–based cropping systems of the developing world. Field trials conducted over 10 years in northern China show that mirid bugs (Heteroptera: Miridae) have progressively increased population sizes and acquired pest status in cotton and multiple other crops, in association with a regional increase in Bt cotton adoption. More specifically, our analyses show that Bt cotton has become a source of ...


Assessment of soil erosion under woodlands using USLE in China

Frontiers of Earth Science, Vol. 5, No. 2. (2011), pp. 150-161,


Universal Soil Loss Equation (USLE), originally developed by the USDA for agricultural lands and then used throughout the world, was applied in mountainous forest terrain in China. The woodland area was divide into 100 m × 100 m grid cells. The ArcInfo 9.2 GIS software provided spatial input data was used to predict the spatial distribution of the average annual soil loss on grid basis. The average rainfall erositivity factor (R) for national woodlands was found to be 21–1798 MJ·mm·ha−1·h−1·a−1. The ...


Precipitation–vegetation coupling and its influence on erosion on the Loess Plateau, China

CATENA, Vol. 64, No. 1. (30 November 2005), pp. 103-116,


The relationships between precipitation, vegetation and erosion are important and are unsolved issues in the field of earth surface processes. Based on data from the Loess Plateau of China, some non-linear relationships between forest cover (Cf), mean annual rainfall erosivity (Re) and annual precipitation (Pm) have been found. A threshold has been identified at Pm = 450 mm, that is, when Pm is < 450 mm, Cf is low and basically does not vary with Pm; when Pm exceeds 450 mm, Cf increases rapidly. ...

Effects of plant species diversity on soil conservation and stability in the secondary succession phases of a semihumid evergreen broadleaf forest in China

Journal of Soil and Water Conservation, Vol. 67, No. 4. (01 July 2012), pp. 311-320,


One of the most studied aspects of ecosystems in recent years has been the relationship between plant species diversity and ecosystem functions; however, the relationship with one such ecosystem function, soil conservation, has been less well studied. We established forest plots in the secondary succession phases of a semihumid evergreen broadleaf forest in China. The plots differed in plant species richness but had otherwise similar soil-erosion factors, observed surface runoff, sediment, and total phosphorus (P) loss. We analyzed the relationship between ...


China gets serious about its pollutant-laden soil

Science, Vol. 343, No. 6178. (28 March 2014), pp. 1415-1416,


A recent national survey found that 2.5% of China's arable land is too contaminated to grow food safely. The survey's details were so alarming that they were declared a "state secret." Now, the central government appears eager to tackle the problem; China's latest 5-year plan singles out five industries as egregious soil polluters and sets a target to reduce, by 2015, discharges of heavy metals by 15% from 2007 levels. ...


Soil erodibility and its estimation for agricultural soils in China

Journal of Arid Environments, Vol. 72, No. 6. (June 2008), pp. 1002-1011,


Soil erodibility (the K factor in the Universal Soil Loss Equation, USLE) is an important index to measure soil susceptibility to water erosion, and an essential parameter needed for soil erosion prediction. To evaluate the appropriateness of the nomograph and other methods for estimating the K factor for the USLE and to develop a relationship for soil erodibility estimation for Chinese soils, a set of soil erodibility values was calculated using soil loss data from natural runoff plots at 13 sites ...


Development of topsoil grain size index for monitoring desertification in arid land using remote sensing

International Journal of Remote Sensing, Vol. 27, No. 12. (1 June 2006), pp. 2411-2422,


The grain size composition of topsoil characterizes the soil texture and other physical properties. The coarsening of topsoil grain size is a visible symbol of land degradation; thereby the change in topsoil grain size can be potentially used to monitor desertification using remote sensing. This study proposes a new index for detecting topsoil grain size composition through ground in situ soil spectral reflectance measurements and soil physical analysis in the laboratory. The proposed topsoil grain size index (GSI), which has a ...

Afforestation in China cools local land surface temperature

Proceedings of the National Academy of Sciences, Vol. 111, No. 8. (25 February 2014), pp. 2915-2919,


[Significance] China has the largest afforested area in the world. Afforestation not only contributes to increased carbon storage but also alters local albedo and turbulent energy fluxes, which offers feedback on the local and regional climate. This study presents previously unidentified observational evidence of the effect of large-scale afforestation on land surface temperature (LST) in China. Afforestation decreases daytime LST, because of enhanced evapotranspiration, and increases nighttime LST. This nighttime warming tends to offset daytime cooling in dry regions. These results ...


A 3,500-year tree-ring record of annual precipitation on the northeastern Tibetan Plateau

Proceedings of the National Academy of Sciences, Vol. 111, No. 8. (25 February 2014), pp. 2903-2908,


[Significance] This paper describes the production and climatic interpretation of a tree-ring width chronology that is currently the longest, absolutely dated series produced for the northeastern Tibetan Plateau and one of the longest in the world. The method of chronology construction enables comparison of variations in precipitation totals over long timescales as well as shorter periods. Precipitation in this region during the last 50 years has been historically high—likely higher than for any equivalent length period in at least 3,500 years, ...


Estimation of throughfall erosivity in a highly diverse forest ecosystem using sand-filled splash cups

Journal of Earth Science In Journal of Earth Science, Vol. 21, No. 6. (2010), pp. 897-900,


Sand-filled splash cups were used to study the erosive power of rainfall and throughfall in the humid subtropics of Southeast China. The splash cup measurements yielded precise and reproducible results under both open field conditions and forest vegetation. The splash cups were exposed to specific forest stands of different ages and to selected species (Schima superba, Castanopsis eyrei, Daphniphyllum oldhamii, Lithocarpus glaber) in the Gutianshan (古田山) National Nature Reserve (GNNR). The results of the measurements under forest vegetation show that the ...


Reduction of primary production and changing of nutrient ratio in the East China Sea: Effect of the Three Gorges Dam?

Geophysical Research Letters, Vol. 33, No. 7. (15 April 2006), L07610,


It has been documented that the global proliferation of dam construction on the major river has reduced nutrient and sediment loading to coastal environments. As a consequence, dams can impact marine ecological systems by changing nutrient concentrations and ratios in the coastal zone. From 1998–2004, we conducted a high resolution oceanographic investigation of the East China Sea (ECS) before and after the first filling phase (June 2003) of the Three-Gorges Dam (TGD). We found that the Si:N ratio in the River ...


Dam impacts on the Changjiang (Yangtze) River sediment discharge to the sea: The past 55 years and after the Three Gorges Dam

Water Resources Research, Vol. 42, No. 4. (15 April 2006), W04407,


In 5 recent years (2000–2004), the Changjiang (Yangtze) River has discharged past Datong (600 km from the river mouth) an average of ∼250 million tons (mt) of sediment per year, a decrease of more than 40% since the 1950s and 1960s, whereas water discharge at Datong has increased slightly. Water and sediment discharge data from the upper, middle, and lower reaches of the river suggest that the reduction of the Changjiang sediment load has occurred in two phases between 1950 and ...


Three-Gorges dam - Experiment in habitat fragmentation?

Science, Vol. 300, No. 5623. (23 May 2003), pp. 1239-1240,


Habitat fragmentation is the primary cause of the loss of biodiversity and ecosystem services, but its underlying processes and mechanisms remain poorly understood. Studies of islands and insular terrestrial habitats are essential for improving our understanding of habitat fragmentation. We argue that the Three-Gorges Dam, the largest that humans have ever created, presents a unique grand-scale natural experiment that allows ecologists to address a range of critical questions concerning the theory and practice of biodiversity conservation. ...


A comparison of WEPP and SWAT for modeling soil erosion of the Zhangjiachong Watershed in the Three Gorges Reservoir Area

Agricultural Water Management, Vol. 96, No. 10. (October 2009), pp. 1435-1442,


Soil and water conservation is important for the Three Gorges Reservoir Area in China, and quantification of soil loss is a significant issue. In this study, two widely used models – the Water Erosion Prediction Project (WEPP) and the Soil and Water Assessment Tool (SWAT) – were applied to simulate runoff and sediment yield for the Zhangjiachong Watershed in the Three Gorges Reservoir Area. The models were run and the simulated runoff and sediment yield values were compared with the measured ...
