中国内蒙古自治区荒漠化程度2002年监测数据集

基于内蒙古自治区范围内2002年的MODIS数据，选取FVC、MSAVI、LST、TVDI指标，通过信息叠加分析、分类、判别等工作生成不同气候分区各指标判别值，再根据原国家林业局荒漠化监测气候分区规定，生成内蒙古4个气候区的2002年荒漠化程度年度监测数据。本数据集划分为四个荒漠化气候类型区，分别为semiarid-半干旱区、arid-干旱区、superarid -极干旱区、subhumid -亚湿润干旱区。数据类型为shp格式，数据投影为Lambert_Azimuthal_Equal_Area，空间分辨率均为1 km。

Based on MODIS data covering the Inner Mongolia Autonomous Region in 2002, four indicators including FVC, MSAVI, LST, and TVDI were selected. Through operations such as information overlay analysis, classification, and discrimination, the discriminant values of each indicator for different climate zones were derived. Then, in accordance with the desertification monitoring climate zoning regulations formulated by the former State Forestry Administration, annual monitoring data of desertification severity for the four climate zones in Inner Mongolia in 2002 were generated. This dataset is divided into four desertification climate zones: semiarid (semi-arid region), arid (arid region), superarid (extremely arid region), and subhumid (sub-humid arid region). The data is stored in shp format, with the projection set as Lambert_Azimuthal_Equal_Area and a uniform spatial resolution of 1 km.
