Assessment of Grassland Ecosystem Service Value in Response to Climate Change in China

The assessment of ecosystem services provides an intuitive source information on the benefits humans derive from ecosystems. equivalent factor method was applied to calculate service value (ESV) in combination with net primary productivity (NPP) calculated by process-based Carnegie–Ames–Stanford approach (CASA) model. This study evaluated grassland ESV and its spatial evolution characteristics China 2001 2020 revealed impact climate factors. For 2001–2020, annual ranged 1.17 × 1012 1.51 yuan (renminbi, yuan—the same below; $0.15 1012–$0.20 1012, US dollar), average 1.37 ($0.18 1012). pattern per unit area notably characterized increase northwest southeast. However, relatively large (exceeding 10 106 yuan; $1.30 106) northern western provinces lowest (less than 0.2 $0.03 eastern southern provinces. In last 20 years, has increased most areas decreased only some areas. Compared first usually less 20%. it parts China, mainly concentrated alpine meadow Qinghai–Tibet Plateau around Yili region Xinjiang. Precipitation main regulating had a positive 79% areas, especially China. Evapotranspiration sunshine hours exhibited marginal ESV, but temperature relative humidity no significant effect. Overall, this contributes exploring spatiotemporal patterns factors thereby providing reliable guidance for management.
