Estimating the Impact of Ecological Migrants on the South-to-North Water Diversion in China.

The South-to-North Water Diversion (SNWD) provides significant benefits in facilitating water security and improving ecology in northern China. However, few studies have estimated the water value of the SNWD and the corresponding subsequent subsidies of the ecological migrants in Xichuan County displaced by the project. Based on the Google Earth Engine (GEE), this study analyzed the water ecosystem changes in Xichuan County in 2000-2020 and valued the water transfer of the SNWD.

Satellite-based ground PM estimation using a gradient boosting decision tree.

Fine particulate matter with an aerodynamic diameter less than 2.5 μm (PM) is one of the major air pollutants risks to human health worldwide. Satellite-based aerosol optical depth (AOD) products are an effective metric for acquiring PM information, featuring broad coverage and high resolution, which compensate for the sparse and uneven distribution of existing monitoring stations.

Contribution of anthropogenic CO in China to global radiative forcing and its offset by the ecosystem during 2000-2015.

As the world's largest developing country, quantifying China's CO contribution to global warming is important for assessing the climate effects of anthropogenic and natural factors. We used global CO assimilation data from 2000 to 2015 and a carbon-climate parameterized scheme to analyze anthropogenic carbon emissions and their climatic effects while considering the climate effects of the terrestrial ecosystem carbon sink. Three results are notable: (1) From 2000 to 2015, global anthropogenic emissions increased from 2.

Spatial Association of Urbanization in the Yangtze River Delta, China.

China is urbanizing rapidly, but current research into the spatiotemporal characteristics of urbanization often ignores the spatial and evolutionary associations of cities. Using the theory of spatial polarization and diffusion, together with a systematic analysis method, this study examined the spatial development process of urbanization in the Yangtze River Delta (YRD) region of China during 1995-2015. Results showed clear patterns in the scale and hierarchy of regional urbanization.

Land Cover Change Intensifies Actual and Potential Radiative Forcing through CO in South and Southeast Asia from 1992 to 2015.

Land cover change (LCC) and its impact on CO sequestration and radiative forcing (RF) could dramatically affect climate change, but there has been little effort to address this issue in South and Southeast Asia over a long period of time using actual land cover information. In this study, annual land cover data from 1992 to 2015 were used to assess the CO flux and corresponding RF due to LCC in South and Southeast Asia. The results showed that 553.

Preliminary estimation of the realistic optimum temperature for vegetation growth in China.

The estimation of optimum temperature of vegetation growth is very useful for a wide range of applications such as agriculture and climate change studies. Thermal conditions substantially affect vegetation growth. In this study, the normalized difference vegetation index (NDVI) and daily temperature data set from 1982 to 2006 for China were used to examine optimum temperature of vegetation growth.
