西双版纳橡胶成林分布及变化数据集（2014-2018）

基于西双版纳2014年和2018年旱季（10-4月）Landsat-8 OLI遥感影像，利用橡胶林落叶-新叶萌生期内（1-3月）归一化焚烧指数变化率（CRNBR）算法，运用当年新叶萌生期植被分布（NDVI）与海拔高度数据（ASTER GDEM）进行掩膜提取，分别获取了 2014 年和2018 年西双版纳橡胶成林空间分布数据。基于 ArcGIS 10.5 平台分析了橡胶成林时空格局和种植面积增减变化，得到西双版纳橡胶成林分布及变化数据集（2014-2018）。该数据集包括：（1）研究区范围地理信息系统数据；（2）2014和2018年橡胶成林空间分布数据；（3）2014-2018年橡胶成林分布变化数据，包括增加区、减少区和不变区；（4）2014和2018年西双版纳及相应市县橡胶成林种植面积及变化的统计数据。该数据集存储为.shp、.tif、和.xlsx格式，共由39个数据文件组成，数据量为77.4 MB（压缩为1个文件2.55 MB）。基于该数据集的分析研究成果发表在《地球信息科学学报》2019年第21卷第3期。

Based on the Landsat-8 OLI remote sensing images of the dry season (October-April) in Xishuangbanna in 2014 and 2018, the spatial distribution data of mature rubber plantations in Xishuangbanna in 2014 and 2018 were obtained respectively by using the Change Rate of Normalized Burn Ratio (CRNBR) algorithm during the defoliation and new leaf sprouting period (January-March) of rubber plantations, and performing mask extraction with the vegetation distribution (Normalized Difference Vegetation Index, NDVI) data in the current year's new leaf sprouting period and the elevation data (ASTER Global Digital Elevation Model, ASTER GDEM). Based on the ArcGIS 10.5 platform, the spatiotemporal patterns of mature rubber plantations and the changes in planting area were analyzed, and the Xishuangbanna mature rubber plantation distribution and change dataset (2014-2018) was established. This dataset includes: (1) Geographic information system (GIS) data of the study area boundary; (2) Spatial distribution data of mature rubber plantations in Xishuangbanna in 2014 and 2018; (3) Distribution change data of mature rubber plantations from 2014 to 2018, including expansion areas, contraction areas and stable areas; (4) Statistical data of the planting area and its changes of mature rubber plantations in Xishuangbanna and its corresponding cities and counties in 2014 and 2018. This dataset is stored in .shp, .tif and .xlsx formats, consisting of 39 data files in total, with a total size of 77.4 MB (compressed to 2.55 MB in a single archive file). Research findings based on this dataset have been published in *Journal of Geo-information Science*, Volume 21, Issue 3, 2019.
