资源简介:
作者基于2000-2015年每月的分辨率为1km的SPOT/VEGETATION NDVI数据,运用最大值合成法生成每年的NDVI数据;结合统计年鉴数据,采用趋势分析法和地理探测器模型,计算得到内蒙古植被NDVI变化趋势及影响因子数据集(2000-2015)。该数据集包括地理信息系统空间数据和统计表格数据两种类型。空间数据包括:(1)内蒙古2000-2015年NDVI年变化趋势1km栅格数据;(2)基于2000-2015年NDVI年变化趋势的变化程度分类1km栅格数据;(3)自然因子数据,包括2000-2015年的降水量、平均气温变化趋势、坡向、坡度分级和植被类型1 km栅格数据;(4)以旗、县为基础单元的人为因子地理信息系统数据,包括2000-2015年乡村人口变化趋势、乡村户数变化趋势、乡村劳动力变化趋势、粮食产量变化趋势、农牧民人均纯收入变化趋势和牲畜数量变化趋势等6项属性数据。表格数据包括:(1)基于植被NDVI变化划分的植被变化等级所占的面积及比例;(2)导致内蒙古牧业旗县和非牧业旗县植被NDVI变化的主要影响因素及q值。数据集存储为.tif、.shp 和.xlsx 格式,由47个文件组成,数据量为65.4 MB(压缩为1个文件,12.7 MB)。

The authors first generated annual NDVI datasets via the Maximum Value Composite (MVC) method using monthly 1km-resolution SPOT/VEGETATION NDVI data spanning 2000 to 2015. Then, combined with statistical yearbook data, they employed the trend analysis method and Geodetector model to develop the "Inner Mongolia Vegetation NDVI Change Trend and Impact Factors Dataset (2000–2015)". This dataset includes two main categories of data: GIS spatial data and statistical tabular data. The GIS spatial data consists of four parts: 1. 1km-resolution grid data of annual NDVI change trends in Inner Mongolia from 2000 to 2015; 2. 1km-resolution classified grid data of change degrees based on the annual NDVI change trends during 2000–2015; 3. Natural factor data, including 1km-resolution grid data of precipitation, average air temperature change trends, aspect, slope gradient classification and vegetation type from 2000 to 2015; 4. GIS-based anthropogenic factor data at the banner and county administrative unit level, covering six attribute datasets such as change trends of rural population, rural household count, rural labor force, grain output, per capita net income of farmers and herdsmen, and livestock quantity from 2000 to 2015. The statistical tabular data includes two parts: 1. The area and proportion of each vegetation change category classified based on vegetation NDVI changes; 2. The main driving factors and their corresponding q-values for vegetation NDVI changes in pastoral and non-pastoral banners and counties of Inner Mongolia. The dataset is stored in .tif, .shp and .xlsx formats, consisting of 47 files with a total size of 65.4 MB (compressed into a single file of 12.7 MB).
