基于PSO－PPM模型的江苏省农业水土资源承载力研究

摘要

Abstrca t: Based on the index system was established by the DPSR model, using the PSO-PPM model to evaluate the land and water resources carrying capacity, and divided the grade.The results showed that the cities which had much higher land and water resources carrying capacity were mainly concentrated in the northern and central part of Jiangsu province, the indexes such as water resources of, per unit area agricultural degree, the proportion of high water crops, water conservancy investment had higher impact on the overall carrying capacity.The results meet the practice, the evaluation model was objective and effective.%在用DPSR模型构建科学指标体系的基础上，利用PSO－PPM模型对江苏省各城市的农业水土资源承载力进行了综合评价，并划分了等级，发现江苏省农业水土资源承载力较高的城市主要集中在苏北及苏中地区，单位面积水资源量、农机化程度、高耗水作物种植比例、水利工程投资等指标作用突出。评价结果符合实际，评价模型客观有效。
