摘要: 高标准基本农田建设是夯实农业基础,保障国家粮食安全的重要抓手。以重庆市南岸区为研究对象,从基础地力、利用条件、区位条件3方面筛选出12个指标,构建高标准基本农田建设综合评价体系,引入熵权法、障碍度模型等测算各评价单元的建设潜力和建设难度系数,最后以行政村为评价单元耦合两者评价结果,提出了南岸区高标准基本农田建设时序。结果表明:南岸区已基本具备高标准基本农田条件的耕地面积约76.6 hm2,占永久基本农田总量的11%,其余624.19 hm2耕地可通过土地整治逐步建成高标准基本农田。在空间上,建设潜力较高的区域主要集中在东北部广阳镇,建设难度等级呈现出“南高北低”的分布规律,按照先易后难的建设原则,建设时序也需遵循从北向南的规律依次开展整治工程。研究结果可为南岸区高标准基本农田规划实施提供参考。


Abstract: The construction of high-standard basic farmland is an important grasp to consolidate the agricultural foundation and ensure national food security. Taking Nan’an District of Chongqing as the research object, this paper selects 12 indicators from three aspects of basic geo-power, utilization conditions and location conditions, constructs a comprehensive evaluation system of high-standard basic farmland construction, introduces the method of entropy weight and obstacle degree model to measure the construction potential and difficulty coefficient of each evaluation unit, and finally uses the administrative village as the evaluation unit to couple the two evaluation results, and puts forward the Nan’an District High standard time sequence of basic farmland construction. The results showed that the area of cultivated land with high standard basic farmland conditions in Nan’an area was about 76.6 hm2, accounting for 11% of the total permanent basic farmland. The remaining 624.19 hm2 cultivated land could be gradually built into high standard basic farmland through land renovation. Spatially, the regions with high construction potential are mainly concentrated in Guangyang Town in the northeast of China, and the construction difficulty level shows the distribution law of “high in the South and low in the north”. According to the construction principle of “easy in the first place” and “difficult in the second place”, the construction time sequence also needs to follow the rule of “from north to south” to carry out the renovation project in turn. The research results can provide reference for the implementation of high standard basic farmland planning in Nan’an area.
