摘　　要：在江苏省农用地分等成果更新的基础上,通过指定作物样本调查与统计分析,建立了各二级指标区内分等单元的理论单产与可实现单产模型。分析了江苏省理论产能、可实现产能与实际产能的空间分布情况,并运用克里金插值方法建立了农用地单产与产能的空间分异规律。研究表明,江苏省理论单产、可实现单产与实际单产分布具有较大差异,农用地数量是影响农用地产能的最主要因素。该研究对基本农田划定和耕地质量保护具有重要指导意义。Based on the updated agricultural land classification data, the theoretical productivity and accessible productivity models were constructed for the second class target areas in Jiangsu province using the appointed crops surveying and statistical methods. The theoretical, accessible and actual productivities of agricultural land in Jiang- su province were analyzed, and the spatial variation law was established using the Kriging method. The results showed that the theoretical, accessible and actual productivities had significant differences, and the most important factor impacting agricultural land productivity was agricultural land quantity. This research had important meaning to the basic farmland demarcation and cultivated land quality protection.
