摘要: 良好的耕地自然质量条件和稳定的立地条件是永久基本农田划定的重要基础条件.目前对基本农田的研究多偏重耕地自然质量条件评价方面,而对耕地立地条件研究较少,基本农田被频繁调整,稳定性差.论文以东港市为研究区域,在保障耕地自然条件良好,均一的基础上,从耕地立地条件角度探讨基本农田划定问题,由耕地区位条件因素和耕作便利条件因素构建耕地立地条件评价体系,采用指数衰减法等计算立地条件因素影响作用分值,利用相关性分析等数学模型分析立地条件因素对基本农田划定影响风险范围以及稳定区域,并以实证分析.研究结果表明:1)立地条件是永久基本农田划定的重要组成部分,对基本农田的稳定性影响较大;2)区位因素对基本农田划定存在一定距离的负向型影响,该距离内被占用风险较大,风险距离外区位因素影响为正向型,并呈同心圆状逐级衰减;3)辽宁省东港市立地条件评价结果分4个等级,其中1,2,3级耕地立地条件较优,面积为89 954 hm2,占耕地总面积的86.3%,区位较优,耕作便利,适宜划入基本农田.

Abstract: Good quality and stable site conditions of farmland are important basic qualifications of demarcating permanent basic farmland. The researches of basic farmland concentrated more on farmland quality but less on farmland site conditions, which has made the basic farmland be adjusted frequently and be unstable. Taking the Donggang City in Liaoning Province as the research case, this paper explores the questions of basic farmland demarcating from the point of farmland's site conditions under the condition of guaranteeing the good and uniform quality of farmland. The research constructed the assessment system of farmland site condition by location factors and farming convenience factors. It calculated the quantified effecting values of farmland site condition factors with exponential decay model and calculated the risk distance and stable region with correlation analysis model. The results showed that: 1) the site conditions are the important composition of permanent basic farmland and have great effect on the stability of basic farmland; 2) the location factors have negative impact on the risk of farmland being occupied in certain distance, and have positive impact beyond the risk distance with the effect attenuating gradually in concentric circles; and 3) the farmland site condition in Donggang City is divided into four grades, the area of farmlands of first grade, second grade and third grade is 89 954 hm2, accounting for 86.30% of the farmland. They have better site location and farming convenience, thus are suitable for basic farmland.
