2020 年中国典型县域 30 m 生态系统服务与生态问题数据集

生态系统服务与生态问题数据集包括三类主要生态系统（森林、湖泊/湿地、草地/荒漠）典型县域（清原满族自治县、长白山保护区、会同县、安塞县、鄱阳湖湖区、那曲县、饶河县、科尔沁左翼后旗、环江县）的主要生态服务功能和生态问题。基于遥感数据、地面监测数据与模型模拟结果的综合数据库，主要采用Invest模型框架，评估典型县域的生态服务功能和生态问题，包括：（1）典型区主要生态问题数据集（土壤侵蚀、土地沙化、石漠化）；（2）典型区生态服务功能要素数据集（土壤保持、防风固沙、水源涵养和固碳）。时间为：2020年；空间分辨率为30 m。Ecosystem Services and Ecological Issues Dataset covers the main ecosystem services and ecological issues of typical county-level study areas across three major types of ecosystems: forest, lake/wetland, grassland/desert. The selected typical study areas include Qingyuan Manchu Autonomous County, Changbai Mountain National Nature Reserve, Huitong County, Ansai County, Poyang Lake Region, Naqu County, Raohe County, Horqin Left Rear Banner, and Huanjiang Maonan Autonomous County. This is a comprehensive database integrating remote sensing data, ground monitoring data and model simulation results, which mainly adopts the InVEST model framework to evaluate the ecosystem services and ecological issues of the typical county-level study areas. The dataset consists of two parts: (1) Dataset of major ecological issues in typical areas (soil erosion, land desertification and rocky desertification); (2) Dataset of ecosystem service function elements in typical areas (soil conservation, windbreak and sand fixation, water conservation and carbon sequestration). The temporal coverage is the year 2020, and the spatial resolution is 30 meters.
