摘要：

以江苏省为例，运用定量数理统计、快速聚类分析以及地理信息系统空间分析法，对1980—2020年江苏省农作物种植结构的时空动态变化进行分析。结果表明，40年间江苏省的农作物播种面积和粮食播种面积总体呈下降趋势，其中小麦、水稻播种面积均呈波动式递减趋势，种植比例在2002年均出现大幅度下降，后又小幅回升；而蔬果等经济类作物在40年期间一直保持增长趋势；粮食类作物中的玉米、大豆以及经济类作物中的油料作物变动幅度不显著。40年间共出现14种种植组合模式，小麦、水稻在种植空间分布和种植类型中处于领先地位，2000年以来经济作物的种植类型显著增多。40年间江苏省农作物种植结构时空变化明显，分析掌握其变化特征，可为江苏省农作物种植结构优化提供决策依据。

Abstract:

The temporal and spatial changes of crop planting structure in Jiangsu province from 1980 to 2020 were analyzed by using quantitative mathematical statistics, rapid cluster analysis and geographical system spatial analysis. The results showed that, the crop planting area and grain planting area had generally shown a downward trend in the past 40 years, the planting area of wheat and rice had showed a trend of decreasing wave, the proportion of planting decreased significantly in 2002, and then increased slightly. However, the economic crops such as fruits and vegetables had maintained an increasing trend in the past 40 years. The planting area of corn, soybeans and oil crops had a small change. In the past 40 years, there have been 14 types of planting combination patterns, and wheat and rice were in the leading position in the spatial distribution of planting and planting types. The types of economic crops had increased significantly since 2000. In the past 40 years, the temporal and spatial changes of the crop planting structure in Jiangsu Province had changed significantly. Analyzing and grasping the characteristics of the changes can provide a decision-making basis for the optimization of the crop planting structure in Jiangsu Province.
