吉林省西部耕地变化与“旱改水”时空特征研究数据集(1990–2015)

Temporal-spatial Cultivated Land and Conversion from Dry Farmland to Paddy Dataset in the Western Jilin Province, China(1990–2015)

基于1990年、2000年、2010年和2015年四个时期Landsat TM/ETM/OLI影像数据,对吉林省西部地区耕地变化与旱地-水田转化特征进行分析,得到《吉林省西部耕地变化与"旱改水"时空特征研究数据集》。该数据集包括4组空间数据和3个表格数据。空间数据包括:(1)研究区边界数据;(2)1990、2000、2010和2015年耕地空间分布数据;(3)1990–2000、2000–2010和2010–2015年耕地空间变化数据;(4)1990–2000、2000–2010和2010–2015年耕地内部的旱地与水田之间空间转化数据。表格数据包括:(1)1990–2015年4个时期耕地面积及其变化统计数据;(2)1990–2000、2000–2010和2010–2015年旱地与其他土地覆被类型之间的转化贡献率数据;(3)1990–2000、2000–2010、2010–2015年吉林省西部水田与其他土地覆被类型之间的转化贡献率数据。数据集存储为.tif、.shp和.xlsx格式,由70个文件组成,数据量为40.8 MB(压缩为1个文件,14.9 MB)。基于该数据集的研究成果发表在《遥感技术与应用》2019年第34卷第5期。

Based on Landsat TM/ETM/OLI image data of the 4 annual periods of 1990,2000,2010,and 2015,the characteristics and change in areas of cultivated land and conversion from dry farmland to paddy fields in western Jilin province were analyzed.The dataset included 4 sets of spatial data and 3 sets of tabular data.Spatial data include:(1)study area boundary data;(2)spatial distribution data of cultivated land in 1990,2000,2010,and 2015;(3)spatial change data of cultivated land in 1990–2000,2000–2010,and 2010–2015;(4)Spatial conversion data between dry farmland and paddy fields within cultivated land in 1990–2000,2000–2010,and 2010–2015.The tabular data include:(1)statistical data on cultivated land area and its change during the 4 periods from 1990 to 2015;(2)conversion contribution rate between dry farmland and other land cover types in 1990–2000,2000–2010,and 2010–2015;(3)conversion contribution rate data between paddy fields in western Jilin province and other land cover types in 1990–2000,2000-2010,and 2010–2015.The dataset is stored in.tif,.shp,and.xlsx formats and consists of 70 files with a data volume of 40.8 MB(compressed to 1 file,14.9 MB).The research results based on this dataset are published in Remote Sensing Technology and Applications,Vol.34,No.4,2019.
