“…The temperature and precipitation data from 1990 to 2015 is extracted in this study and the topography factors were considered into the climate data interpolation algorithm to reduce the interpolation error. And the biophysical factors, such as the plant evapotranspiration coefficient and support practice factors used in similar natural conditions [2] were adopted in this study [71][72][73][74][75].…”

Past years have witnessed the transformation of land use at a high frequency and a warmer and drier climate in the Eastern Tibetan Plateau region. To fully understand the spatial-temporal variation of ecosystem services against the changing global backdrop and to provide scientific ecosystem management measures for decision-making, a study was conducted to investigate the major ecosystem services: water yield, soil conservation and crop production from 1990 to 2015 in the Eastern Tibetan Plateau region. Three scenarios-climate change only, land use change only and both land use and climate change-were included in this study to analyze the response of ES to the above-mentioned global changes. The results show that (1) the total quantity of ES reduced in all the three scenarios, the annual ES change was scenarioII < scenarioIII < scenarioI and the periodical characteristics are present in this region; (2) the ES change in spatial distribution varied with different climate change patterns and land use transfer directions; (3) the ES composition of each ecosystem varied with different driving scenarios and different responses of the forest and wetland on climate change and land use changes were observed. Moreover, the trade-off under land use change and climate change respectively was observed in this study. Based on the results, we recommend that the local government take this trade-off and climate change into account when making decisions, continue with desertification control and improve the quality of grassland as well as forests-these efforts should enable us to achieve sustainable development of human beings and the natural ecosystem.

“…Rate of change is the area of specific conversion in proportion to all types of conversions was reported that SLCP had converted nearly 9.0 × 10 6 ha of cropland into forest or grassland nationwide before 2007 (Liu et al, 2008). Additionally, conversion from forest to bare land consisted of a considerable proportion (10.74%) on slopes of > 35°, which demonstrated the damage caused by the Wenchuan earthquake in 2008 (Zhang and Wang, 2008;Wang et al, 2012).…”

“…The degraded zone accounted for 2.44% of the total land area, primarily in the Minshan Mountain and Qionglai Mountain to the west of the Sichuan Basin, which were part of the Wenchuan earthquake zone. A recent study conducted by Wang et al (2012) showed that after the Wenchuan earthquake, the reduction of soil conservation capacity in the earthquake zone averaged 0.90 t/(ha·yr), which was the most affected among the three key ecosystem services (soil conservation, water retention, and carbon sequestration). This indicates that earthquakes not only destroy the natural vegetation but also degrade the soil conservation offered by ecosystems (Zhang and Wang, 2008;Wang et al, 2012).…”

A reduction in soil conservation was also observed in southern Yunnan Valley, which was the result of the large-scale replacement of tropical rainforest with cash crop forest (Li et al, 2007;Zhang and Zou, 2009).…”

“…Despite ecological protection efforts, ecosystems are still suffering severe damage from natural disasters and human activities, leading to ecological function deterioration. For example, the Wenchuan earthquake in Sichuan Province, China in 2008 caused heavy casualties and property losses, and seriously damaged local ecosystems (Zhang and Wang, 2008), which sharply reduced water retention, soil conservation, carbon sequestration, and other ecosystem services (Wang et al, 2012;Yang et al, 2013). During the last century, in the middle and lower reaches of the Changjiang (Yangtze) River, unsustainable human activities such as conversion of lakes to croplands, building of sluices, and construction of embankments considerably reduced the flood regulation provided by lakes and led to an increase in the flood frequency (Li et al, 2005;Yang et al, 2010).…”

Changes in ecosystem service of soil conservation between 2000 and 2010 and its driving factors in southwestern China

Human activities significantly alter ecosystems and their services; however, quantifying the impact of human activities on ecosystems has been a great challenge in ecosystem management. We used the Universal Soil Loss Equation and county-level socioeconomic data to assess the changes in the ecosystem service of soil conservation between 2000 and 2010, and to analyze its spatial characteristics and driving factors in the southwestern China. The results showed that cropland in the southwestern China decreased by 3.74%, while urban land, forest, and grassland areas increased by 46.78%, 0.86%, and 1.12%, respectively. The soil conservation increased by 1.88 × 10 11 kg, with deterioration only in some local areas. The improved and the degraded areas accounted for 6.41% and 2.44% of the total land area, respectively. Implementation of the Sloping Land Conversion Program and urbanization explained 57.80% and 23.90% of the variation in the soil conservation change, respectively, and were found to be the main factors enhancing soil conservation. The 2008 Wenchuan earthquake was one of the factors that led to the degradation of soil conservation. Furthermore, industrial adjustment, by increasing shares of Industry and Service and reducing those of Agriculture, has also promoted soil conservation. Our results quantitatively showed and emphasized the contributions to soil conservation improvement made by implementing ecological restoration programs and promoting urbanization. Consequently, these results provide basic information to improve our understanding of the effects of ecological restoration programs, and help guide future sustainable urban development and regional industrial restructuring.

The 2008 Wenchuan Earthquake triggered massive landslide erosion, especially in mountainous terrain, which had a great impact on carbon storage of the local terrestrial ecosystem. However, variation in carbon flux and restoration of ecosystem function after the Wenchuan Earthquake remain open issues. In this study, we evaluated the current restored vegetation productive capability on the coseismic landslide scars through moderate resolution imaging spectroradiometer (MODIS) net primary productivity (NPP) imagery, and explored their sensitivity to meteorological, topographical, and geological factors. The spatio-temporal evolution and future sustainability of NPP of the landslides after the Earthquake were revealed. The following results were obtained: (i) After 13 years, only 45.36% of the vegetation productivity capability of the landslide scars reached the pre-earthquake level. (ii) Meteorological factors (precipitation and temperature) have strongest influences on vegetation productivity capability recovery over the coseismic landslide scars, followed by topography (aspect, slope, and altitude) and the lithology of landslides. (iii) The extremely significant improvement (p < 0.01) and significant improvement (0.01 ≤ p < 0.05) in annual NPP pixel values from 2008 to 2021 accounted for 18.92% and 28.30% of the total area, respectively. The slight degradation (p < 0.1) in annual NPP pixel values from 2008 to 2021 account for 0.01% of the total area. In general, the NPP has shown an improving trend since the Wenchuan Earthquake. Moreover, 60.95% of the total area shows the trends of continuous improvement in the future. This study provides important insight into how mega-earthquakes affect regional ecosystem carbon flux and contributes to our understanding of ecosystem carbon cycles along with earthquake-induced geohazard chains.
