Health Diagnosis of Cultivated Land Resource Utilization System in Anhui Province Based on DPSIR-TOPSIS Model
[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.
