- 摘要:
- 耕地生态安全直接关系到粮食生产，粮食生产是关系到社会和谐发展的重大政策问题，研究四川省耕地生态安全状况，为保护区域粮食安全、促进社会协调发展提供理论指导和决策参考。以我国西部重要商品粮基地四川省为研究区，基于耗散结构理论，运用数学量化模型分析了该省2000—2013年耕地生态安全级别和演变趋势，并探讨其影响因素。结果表明：（1）四川省近14 a间耕地生态安全级别总体较安全；（2）2000—2008年四川省耕地生态安全逐年得以改善，2008—2013年四川省耕地生态状况略呈下降趋势；（3）影响四川省耕地生态安全状况的因素是社会经济压力因素、农业科技因素和生态环境因素。因此提出继续加强耕地保护宣传力度，提高农民生态保护意识；实施耕地生态安全恢复工程；结合“互联网+”建立覆盖全省的耕地生态安全监控网络体系的对策建议。
- Abstract:
- The ecological security of cultivated land is directly related to grain production, and food production is a major policy issue related to the harmonious development of society. In order to provide theoretical guidance and decision-making reference for the regional food security and promoting the coordinated development of the regional grain production, the study on the ecological security of cultivated land in Sichuan Province was carried out. We took the Sichuan Province as the study area of the important commodity grain base in Western China. Based on the dissipative structure theory, the mathematical model was used to analyze the ecological security level and evolution trend of cultivated land in the period from 2000 to 2013 in Sichuan Province, and to explore its influencing factors. The results show that:(1) the ecological security level of cultivated land in Sichuan Province is more secure in 14 years; (2) the ecological security situation of cultivated land in the period from 2000 to 2008 was in the trend of improving year by year, and the security situation of cultivated land in the period from 2008 to 2013 slightly decreased; (3) the main influencing factors are the socioeconomic pressure factors, the agricultural science and technology factors and the ecological environment factors. So, it is necessary to enhance the publicity of cultivated land protection and the farmers’ consciousness in ecological protection, to carry out the ecological safety restoration for cultivated land, and to establish a monitoring network system on ecological safety of cultivated land based on the internet plus.
