摘要
中国内蒙古自治区地处中国内蒙古高原,是蒙古高原在中国境内的主体区域,也是我国荒漠化和沙化监测的重点区域,土地荒漠化和沙化严重。开展区域年度荒漠化监测是掌握荒漠化动态变化,全面分析荒漠化成因等方面研究的基础。研究基于内蒙古自治区范围内2001年至2021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,基于各指标判别值,生成内蒙古4个气候区的2001-2021年荒漠化程度年度监测数据。本数据集可为荒漠化变化、驱动机制等方面的研究提供数据支撑。
Located in China's Inner Mongolia Plateau,Inner Mongolia Autonomous Region is the main area of the Mongolian Plateau in China,and it is also a key research area for desertification and sandification monitoring.The land in this area is severely desertified and sandificated.Carrying out annual monitoring according to the characteristics of desertification land in this region is a necessary support for the research on grasping the dynamic characteristics of desertification and comprehensively analyzing the causes of desertification.We based the monitoring research on the MODIS data from 2001 to 2021 in the Inner Mongolia Autonomous Region and selected FVC,MSAVI,LST,TVDI indicator to generate indicator discriminant values through information overlay analysis,classification,and discrimination.And according to the zoning regulations,we obtained the annual monitoring data of desertification degree from 2001 to 2021 in 4 climate zones in Inner Mongolia.This dataset can provide data support for studies on desertification changes and driving mechanisms and so on.
