【摘要】：[目的]永久性基本农田划定是稳定耕地面积,控制建设用地无限制扩张的重要手段。[方法]文章以物-场模型为基础,将基本农田划定产生的影响理解为基本农田保护区划定、基本农田功能要素以及基本农田保护区影响场三要素有机组合所形成的系统效应或功能。并借鉴空间相互作用的引力模型,构建了包含基本农田划定适宜性、基本农田功能要素协调性以及距离系数的基本农田划定合理性评价模型。[结果]选取泽州县新一轮基本农田保护区为研究区域,对其保护区划定合理性进行评价,并依据评价结果划分为高度合理区、中度合理区、一般合理区、较不合理区和不合理区,并提出相应管理措施。通过定量化分析,泽州县基本农田划定合理区域占总面积的82%,保护区划定较为合理。[结论]该研究结果可为管理决策部门进行基本农田保护区空间布局合理性评价、为合理安排基本农田生产、生态等功能、基本农田布局调整提供依据。
[Abstract]:[Objective] permanent basic farmland delineation is an important means to stabilize cultivated land area and control the unlimited expansion of construction land. [Methods] based on the material-field model, the influence of the demarcation of basic farmland was understood as the delineation of the basic farmland reserve. The system effect or function formed by the organic combination of the basic farmland function elements and the three elements of the influence field of the basic farmland reserve. The suitability of the basic farmland delineation was constructed by using the gravitational model of spatial interaction. The rationality evaluation model of basic farmland demarcation based on coordination of basic farmland functional elements and distance coefficient. [Results] the new round of basic farmland reserve in Zezhou County was selected as the research area, and the rationality of the delineation of the reserve was evaluated. According to the evaluation results, it was divided into high reasonable area, moderate reasonable area and general reasonable area. Through quantitative analysis, it is found that the rational area of basic farmland in Zezhou County accounts for 82% of the total area, and the protected area is more reasonable. [Conclusion the results of this study can be used to evaluate the rationality of the spatial distribution of the basic farmland reserve for the management and decision-making departments, and to provide the basis for the rational arrangement of the basic farmland production, ecological functions, and the adjustment of the basic farmland layout.
