摘要:
[目的]研究安徽省2007-2016年间耕地资源利用系统的健康状况,为今后的工作提供参考。[方法]构建DPSIR指标评价体系,并利用TOPSIS模型测度了10 a间安徽省耕地资源利用系统健康状况,同时采用障碍度模型剖析了主要的限制因素。[结果]2007-2016年安徽省耕地资源利用系统健康水平由不健康等级转为亚健康等级,健康状况有了明显改善;总体来看,安徽省耕地资源利用系统健康准则层障碍度最高的是压力子系统,主要障碍因子为GDP增长率、农作物受灾面积、农药使用量、建设占用耕地面积、农用塑料薄膜使用量等。[结论]应用DPSIR模型构建的安徽省耕地资源利用系统评价指标体系和运用TOPSIS法分析耕地资源利用系统的健康水平是合理可行的。虽然安徽省总体健康水平呈现稳步上升趋势,但是受压力子系统的限制,安徽省耕地资源利用系统仍处于亚健康水平。

Abstract:
[Objective] To study the health status of cultivated land resource utilization system in Anhui Province during 2007-2016 in order to provide references for future work. [Methods] The DPSIR index evaluation system was constructed, and the health status of cultivated land resource utilization system in Anhui Province in the past 10 years was measured by using TOPSIS model. Meanwhile, the obstacle model was used to analyze the main restrictive factors. [Results] From 2007 to 2016, the health level of cultivated land resource utilization system in Anhui Province was changed from unhealthy to sub-healthy, and the health condition was improved significantly. Generally, the most serious obstacle in the health criteria of cultivated land resource utilization system was the pressure subsystem. The main obstacles were GDP growth rate, crop disaster area, pesticide use, farmland occupied by construction, and agricultural plastic film use. [Conclusion] Using DPSIR model to construct the evaluation index system of cultivated land resources utilization system and using TOPSIS method to analysis the health level of cultivated land resource utilization system is feasible in Anhui Province. Although the overall health level in Anhui Province shows a steady upward trend, the utilization system of cultivated land resources is still at a sub-health level limited by the pressure subsystem.
