Health Evaluation of Urban Cropland in Plateau Mountainous Areas and Diagnosis of Obstacle Factors:A Case Study of Kunming City
摘要
Abstract
The health of cultivated land is related to the national food security strategy and of great significance for the construction of agricultural power and the modern and high-quality development of Chinese-style agricultural modernization.Studying the health of the arable land in the plateau mountains areas is conducive to protecting the quality and production capacity and ecological environment of cultivated land in ecological fragile areas.In this study,Kunming City was selected as the study area,we constructed the PSR model of arable land health evaluation index system,and utilized the entropy weight TOPSIS method and obstacle degree model to evaluate the arable land health status and diagnose obstacle factors.The results showed that:(1)the pressure,status and response indices of cultivated land in Kunming were 0.315,0.634 and 0.367,respectively,with health grades of healthy and sub-healthy;the comprehensive index was 0.346,and cultivated land health was in sub-healthy grade.(2)Combined with the agricultural function zoning,the health level of cultivated land in each district and county showed a certain spatial distribution law:the green agricultural demonstration area in Dianchi Lake Basin is centered on Dianchi Lake,and the surrounding basin was low and the periphery was high.The efficient modern agricultural area around the main city took the northeast-southwest as the main axis,and gradually decreased from the axis to the outside.The northern mountainous characteristic ecological agricultural area was high in the south and low in the north.(3)The primary factor affecting the overall cropland health in Kunming was cropland pressure,followed by cropland status,and finally cropland response.Among them,the population density,use of pesticide,use of agricultural fertilizer,cropland planting structure,and use of agricultural plastic film were the main influencing obstacle factors.The inclusion of high standard farmland construction potential cropland ratio and integrated soil and water management area indicators into the PSR model of cropland health evaluation index system is operable and could effectively evaluate the level of cropland health and provide strategies for cropland protection.关键词
