太湖周边地区耕地生产力及其变化数据集（1985-2010）

太湖周边地区是中国经济快速发展地区和传统粮食高产区。基于卫星遥感数据、气象数据、土壤普查数据、耕地调查和野外土壤监测数据，借助GIS空间分析工具和联合国粮农组织（FAO）农业生态带（AEZ）模型，计算了太湖周边地区耕地生产力及其变化数据集。该数据集包括：（1）研究区范围地理信息系统数据；（2）1985、2000和2010年耕地空间分布数据；（3）1985至2010年耕地增减空间变化及转化类型数据；（4）1985、2000和2010年耕地生产力空间分布数据；（5）1985、2000和2010年耕地生产力等级空间分布数据；（6）1985-2010年耕地变化区生产力等级空间分布数据。数据集存储为.tif和.shp格式，空间分辨率为250m，数据压缩为104MB。该数据集的分析研究成果发表在《地理科学》2015年35卷第8期。

The peri-Taihu Lake region is a region with rapid economic development and a traditional high-yield grain production base in China. Based on satellite remote sensing data, meteorological data, soil census data, cultivated land survey data and field soil monitoring data, and with the aid of GIS spatial analysis tools and the Agro-Ecological Zoning (AEZ) model of the Food and Agriculture Organization of the United Nations (FAO), a dataset of cultivated land productivity and its changes in the peri-Taihu Lake region was compiled. This dataset includes:
(1) Geographic Information System (GIS) data of the study area boundary;
(2) Spatial distribution data of cultivated land in 1985, 2000 and 2010;
(3) Data on spatial changes in the increase and decrease of cultivated land and their conversion types during 1985–2010;
(4) Spatial distribution data of cultivated land productivity in 1985, 2000 and 2010;
(5) Spatial distribution data of cultivated land productivity grades in 1985, 2000 and 2010;
(6) Spatial distribution data of productivity grades in areas with cultivated land changes during 1985–2010.
The dataset is stored in .tif and .shp formats, with a spatial resolution of 250 m, and has a compressed size of 104 MB. The analytical and research findings based on this dataset were published in *Scientia Geographica Sinica*, Volume 35, Issue 8, 2015.
