青藏高原8千米分辨率土壤保持数据集（1990-2015）

生态系统服务是生态系统为人类提供的诸多惠益。土壤保持作为陆地生态系统提供的主要调节服务之一，是防止区域土地退化、降低洪涝灾害发生频率的重要保证，其常用土壤保持量（Soil Conservation, SC）进行评估。作为国家生态安全战略格局的重要组成部分，深入探讨青藏高原地区土壤保持的时空分布对我国的生态文明建设及可持续发展具有深远意义。基于修正的通用土壤流失方程（RUSLE），使用GIMMS NDVI 3gv1.0 数据 、ASTER GDEM、气象站点及中国土壤数据集等多种数据生成了青藏高原地区8km分辨率土壤保持数据集（1990-2015）。

Ecosystem services are the manifold benefits that natural ecosystems deliver to humanity. Soil conservation, one of the primary regulating services provided by terrestrial ecosystems, is a crucial guarantee for preventing regional land degradation and reducing the frequency of flood disasters. It is commonly evaluated using the Soil Conservation (SC) metric. As an important component of China's national ecological security strategic framework, in-depth investigation of the spatio-temporal distribution of soil conservation in the Qinghai-Tibet Plateau is of far-reaching significance to China's ecological civilization construction and sustainable development. Based on the Revised Universal Soil Loss Equation (RUSLE), a soil conservation dataset with an 8 km spatial resolution for the Qinghai-Tibet Plateau spanning 1990 to 2015 was developed using multiple datasets including GIMMS NDVI 3gv1.0, ASTER GDEM, meteorological station data, and the China Soil Dataset.
