基于产能稳定的高标准基本农田建设区选址实证研究

Research on sitelocation of high standard basic farmland construction area based on stable capacity

建设具有稳定产能的高标准基本农田对于确保粮食安全、实现国家长治久安具有重要的现实意义。以江汉平原粮食主产区潜江市为例,在考察高标准基本农田耕地潜力的基础上,重点评估其产能稳定性,构建评价指标体系,借助理想解逼近法对研究区耕地资源质量进行综合评价,以确定高标准基本农田建设选址区。研究表明:潜江市耕地质量总体较好,潜力水平整体较高、局部较低,高标准基本农田建设的潜力区可分为高、低潜力两区,分别占耕地总面积的61. 19%和38. 81%;高标准基本农田建设稳定区可分为高稳定区、中稳定区和低稳定区,分别占耕地总面积的20. 78%、54. 80%和24. 42%;将潜力区和稳定区进行空间叠加,得到高稳定高潜力区、中稳定高潜力区、高稳定低潜力区、中稳定低潜力区、低稳定高潜力区和低稳定低潜力区6个建设分区,选定高稳定高潜力区和中稳定高潜力区作为高标准基本农田建设选址区,面积为579. 98 km2,占区域总面积的47. 22%。这为完善高标准基本农田建设评价体系、真正落实保护耕地、确保粮食安全的基本国策,推进农业可持续发展提供了实证依据。

It is of great practical significance to establish high standard basic farmland with stable capacity to ensure food security and achieve long term peace and stability in the country. Taking the Qianjiang City,a main grain basis of investigating the potential of big P h roducing area of Jianghan Plain,as an example,on the standard basic farmland, the paper mainly evaluates the stability of its productivity and constructs the evaluation index system. By means of the ideal solution approximation method, the quality of cultivated land in the study area is evaluated comprehensively to determine the location of high standard basic farmland construction site. The research shows that the quality of cultivated land in Qianjiang City is generally better and the potential level is higher overall and locally lower. The potential area of high standard basic farmland construction can be divided into high and low potential areas,accounting for 61. 19 and 38.81 ~ of the total area of cultivated land,respectively; Percentage of areas for basic farmland construction can be di and low stability area, accounting for 20. 78 vided into high stability ~,54. 80 ~ and 24. 4 high midd standard stable le stability area 2 ~ of the total area of cultivated land respectively; Spatially superimpose the potential area and the stable area to obtain six construction zones of high stable high potential zone,middle stable high potential zone, high stable low potential zone,middle stable low potential zone,low stable high potential zone,and low stable low potential zone. The high stable high potential area and medium stable high potential area were selected as the high standard basic farmland construction site with an area of 579. 98 km^2 ,accounting for 47.29 of the total area. It is expected that this study will provide some theoretical and empirical evidence for improving the evaluation system of high standard basic farmland construction, implementing the basic state policy of protecting cultivated land and ensuring food security, and promoting the sustainable development of agriculture
