摘要：

本研究旨在探讨河北省耕地生态的现状及其存在的问题，通过明确各影响因子逐年的变化情况及主要障碍因子，为河北省耕地生态安全保护提供建议。依据2011—2020年的统计年鉴数据，基于驱动力-压力-状态-影响-响应(DPSIR)模型，构建河北省耕地生态安全评价指标体系，以此系统评估该省在此期间耕地生态安全的动态变化。并运用障碍度模型分析制约河北省耕地生态安全指数提升的主要因素。结果表明：（1）2011—2020年河北省的耕地生态安全综合水平从“临界安全”等级上升至“较安全”等级，整体上显示出上升趋势；（2）河北省耕地生态安全分为2011—2017年、2017—2020年2个阶段，第一阶段受农药、化肥和农膜的影响导致安全指数下降；第二阶段农业向高层次的绿色发展转型，安全指数上升；（3）2011—2020年主要障碍因素由有效灌溉面积比、第一产业比重及化肥、农药和农膜的使用强度转变为人均耕地面积、土地垦殖率、人口密度、城镇化水平、第一产业比重。基于此，提出发展绿色农业、加大耕地治理投入、控制人口增长、完善耕地保护制度、提高民众耕地保护意识等改善耕地生态安全的建议。

Abstract:

This study aims to assess the ecological status of cultivated land in Hebei Province and identify associated issues, with the objective of providing recommendations to enhance the ecological security of cultivated land in the region. The methodology employed involved the systematic analysis of annual changes in key driving factors and primary obstacles. The evaluation index system of cultivated land ecological security in Hebei Province was established based on the Driving Force-Pressure-State-Impact-Response (DPSIR) model. This system was used to systematically assess the dynamic changes of cultivated land ecological security in the province during the period from 2011 to 2020. The analysis also utilized the obstacle degree model to identify and analyze the primary factors hindering the enhancement of the cultivated land ecological security index in Hebei Province. The results indicated that (1) the comprehensive level of cultivated land ecological security in Hebei Province from 2011 to 2020 increased from the ‘critical security’ level to the ‘safer’ level, manifesting a sustained positive trajectory; (2) the cultivated land ecological security of Hebei Province was divided into two distinct phases: 2011-2017 and 2017-2020. The security index exhibited a decline in the first stage due to the impacts of pesticides, chemical fertilizers, and agricultural films, while it increased in the second stage due to the transformation of agriculture to a higher level of green development; (3) the primary impediments from 2011 to 2020 had undergone a shift, transitioning from the ratio of effective irrigated area, proportion of primary industry, and the intensity of chemical fertilizer, pesticide, and agricultural film utilization per unit of cultivated land to the land reclamation rate, population density, urbanization level, and the proportion of primary industry. Consequently, a series of recommendations have been proposed to enhance the cultivated land ecological security. These recommendations encompass the development of green agriculture, augmented investment in cultivated land, population control measures, the refinement of the cultivated land protection system, and the promotion of public awareness regarding cultivated land protection.
