摘　　要：以河南省新郑市为研究区域,从耕地区位条件、耕作便利程度、规划约束和生态控制4个方面构建了高标准农田建设空间稳定性评价指标体系,采用生态位适宜度模型,对新郑市高标准农田空间稳定性进行分级,遴选出空间稳定性高的区域。研究结果表明:新郑市高标准农田建设高度稳定地块面积28 989.64 hm2,占耕地总面积的53.52%;较稳定地块面积9 075.89 hm2,占耕地总面积的16.76%;较不稳定和不稳定地块面积16 102.4 hm2,占耕地总面积的29.72%。从空间分布来看,西部和南部耕地稳定性明显高于北部和东部区域,空间稳定性差的区域主要为市区、乡镇、产业集聚区周边和道路两侧区域,且随着港区的不断发展,东部区域空间稳定性将逐渐减弱。该研究结果客观反映了新郑市各区域农田的空间稳定性状态,符合当地实际,可为高标准农田建设规划和新一轮土地整治规划编制提供科学支撑。It is China＇ s significant means about the construction of well-facilitated farmland which stabilize agricultural production and ensure national food security. The natural quality condition and spatial stability of farmland are the important foundation on well-facilitated farmland construction. At present, the study about well-facilitated farmland emphasizes the natural quality of farmland, there is little research on the stability of spatial layout. It was occupied after the well-facilitated farmland was built, resulting in great waste. Therefore, it should be considered not only the natural endowments of farmland, but also the stability of its spatial layout about the well-facilitated farmland construction under the background of sustained and rapid socio-economic development. An empirical research was conducted in Xinzheng City to study spatial stability evaluation of well-facilitated farmland. In order to further improve the permanent stability of the well-facilitated farmland construction projects, the index system was established from different aspects of locational conditions of farmland, its convenience degree, land and urban plan constraint and ecology control, totally 10 indicators were selected during the evaluation. The results showed that the spatial stability level of well-facilitated farmland construction in Xinzheng City obtained by using niche-fitness model was consistent with the results of field investigation, and the validity of the model was verified. The key factors restricting of well-facilitated farmland space can be reflected perfectly, at the same time the limitation of the subjective empowerment in current evaluation model carl be avoided. The theory provided a new method, which could extend the application range of the theory of ecological niche; according to the spatial stability suitability index, the spatial stability of well-facilitated farmland in Xinzheng City was divided into four grades： stability, relatively stability, relatively unstability and unstability, and 28 989.64
