Diagnosis of ecological security of cultivated land in Henan Province based on PSR model

摘要：
耕地安全是关系国家粮食安全、经济发展及社会稳定的重大问题.采用层次分析法和PSR(压力-状态-响应)模型,通过构建耕地生态安全评价指标体系,对2008-2018年河南省耕地安全及区域差异进行综合分析,结果表明,研究期内河南省耕地生态安全状况整体不佳,有10个地级市耕地资源仍处于临界安全状态.同时,指标权重值反映出人口自然增长率、城镇化率和耕地垦殖率等是影响耕地综合安全指数的主要因素.未来,需实施差异化的耕地保护政策,结合耕地轮作耕地试点,探索建立科学有效的耕地生态保护补偿机制.

Cultivated land security is a major issue related to regional and national food security, economic development and social stability. This paper uses the analytic hierarchy process and the PSR(pressure-state-response)model to construct a cultivated land ecological security evaluation index system, and comprehensively analyzes the cultivated land security and regional differences in Henan Province from 2008 to 2018. The results showed that during the study period, the ecological security of cultivated land in Henan Province was generally poor, and the cultivated land resources of 10 prefecture-level cities were still in a critically safe state. At the same time, the index weight value reflects that the natural population growth rate, urbanization rate and cultivated land reclamation rate are the main factors of the comprehensive security index of cultivated land. In the future, it is necessary to implement differentiated cultivated land protection policies, combining with cultivated land rotation and cultivated land pilots, and explore the establishment of a scientific and effective cultivated land ecological protection compensation mechanism.
