In the dataset,we selected the percentage of areas of cropland,basic farmland,and high-yielding fields in each town to represent the proportion of cropland or high-quality cropland.For water resources,the percentage of areas with a recharge modulus greater than200,000 m3/(a·km2)or lower than 10,000 m3/(a·km2)were used to represent the volume of water resources used for agricultural irrigation.For climate,we chose the percentage area with precipitation lower than 200 mm to represent the amount of precipitation.For terrain,we selected the percentage of areas above 15°or 25°slope to represent the limiting factor of the terrain.For geomorphology,the percentage of areas of mountains,hills,and plains were selected to analyze the suitability of ACD.For the distribution of ACD projects,the percentage of areas of high-standard farmland projects and the planning projects to 2020 represent the development levels of the past and future.For ecological planning,the percentage area devoted to agriculture-related functions was selected as being representative of agricultural importance.
