摘要
[目的]探讨三象限法在高标准基本农田建设中的应用,为县域高标准基本农田建设布局与发展模式提供一定依据。[方法]以安徽省宿松县为例,采用三象限法对高标准基本农田的建设区域进行划分,从耕地质量适宜性及社会经济条件可行性2方面对其高标准基本农田建设进行评价。其中,耕地质量从立地条件、耕地理化性状及利用条件等方面选择评价指标,社会经济条件从耕地农业生产力、耕地建设利用状况及群众意愿等方面构建评价指标体系。[结果]高适宜高可行区域的耕地面积为3 046.67hm^2,占建设耕地总面积的14.89%,高适宜低可行区域的耕地面积为10 974.53hm^2,占建设耕地总面积的53.62%,低适宜高可行区域的耕地面积为6 445.73hm^2,占建设耕地总面积的31.49%。在对3个区域的耕地限制性因素及高标准基本农田分布情况进行分析的基础上,提出了高标准基本农田的空间布局和建设模式。[结论]运用三象限法,耕地质量与社会经济条件组合成3个区域。宿松县的高标准基本农田建设布局及发展模式与3个区域动态联系。
[Objective] This paper discusses the application of three quadrant methods in the construction of high standard basic farmland in order to provide basis for the construction layout and development models of high standard basic farmland in County.[Methods] Taking Susong County of Anhui Province as an example, this paper classified the construction areas of high standard basic farmland by using three quadrant methods, and evaluated the construction of high standard basic farmland from two aspects:farmland quality suitability and feasibility of social economic condition. Among them, the qualities of cultivated land were judged from site conditions, physical and chemical properties and utilization condition and so on. While social and economic conditions were from the agricultural land productivity, land use status and the wishes of the public and so on.[Results] The cultivated land area of the high suitability and high feasibility region was 3 046.67 hm2, accounting for 14.89% of the total area of construction land. High suitability and low feasibility region area was 10 974.53 hm2, accounting for 53.62% of the total area of construction land. Low suitability and high feasibility region area was 6 445.73 hm2, accounting for 31.49% of the total area of construction land. Based on the analysis of the constraining factors and the distributions of high standard basic farmland in the three areas, the spatial layout and construction models of high standard basic farmland were put forward.[Conclusion] Using the three quadrant method, the counties were grouped into three regions according to the cultivated land quality and socio-economic conditions. The high standard basic farmland construction layout and development models in Susong were dynamically connected with the three regions.
