全国植被指数图

全国8KM分辨率1999年NDVI逐月数据，栅格值为NDVI（植被指数），NDVI的取值为整数，采用Krasovsky_1940，Albers投影。项目来源：国家重点基础研究项目“中国主要水蚀区土壤侵蚀过程与调控研究”，用于提取植被因子，用于流域水土流失预测和生态环境变化分析等。服务对象为从事地学、水文、水土流失研究的学生和科研人员。数据收集时间为2000年，数据采集地点全国范围，东经73°40′~135°2′30″，北纬3°52′～53°33′。Monthly Normalized Difference Vegetation Index (NDVI) dataset with 8 km spatial resolution across China in 1999. Each grid cell stores NDVI values, which are stored as integers. The dataset is projected using the Krasovsky_1940 ellipsoid and Albers equal-area conic projection. The dataset is supported by the National Key Basic Research Program of China titled "Soil Erosion Processes and Regulation Research in Major Water Erosion Areas of China". It is mainly used to extract vegetation factors, and enables applications such as watershed soil erosion prediction, ecological environment change analysis and other relevant research. The target users are students and researchers engaged in geoscience, hydrology and soil erosion studies. The data was collected in 2000, covering the entire national territory with geographic extents from 73°40′E to 135°2′30″E and 3°52′N to 53°33′N.
