摘要: 为了探究微观区域的“三生”空间适宜性分区,从而为乡镇一级的国土规划和全域土地整治规划提供参考,本文以属于矿粮复合区的湖北省大冶市陈贵镇为研究对象,从构建陈贵镇“三生”空间适宜性评价指标体系入手,运用两维图论聚类算法,对陈贵镇“三生”空间开展适宜性评价与分区研究。研究结果表明:1)陈贵镇镇域适宜的“三生”空间主要呈现为2大块状,1块围绕陈贵村呈零散分布,另1块主要聚集于天台山区;不适宜的“三生”空间主要分布在陈贵镇最南端及东北部,其余呈小斑块零散分布。2)从陈贵镇村域的“三生”空间适宜性来看,等级为适宜的村域,其生产空间、生活空间、生态空间都呈现出均衡性发展,已经接近生产空间集约高效、生活空间宜居适度、生态空间山清水秀的政府规划目标。3)矿业开采活动对陈贵镇“三生”空间适宜性的影响作用显著,不但严重影响生态空间,而且还对农业生产和非矿业生产均产生一定的负面影响作用,从而降低矿粮复合区的社会效益,并可能导致整体空间利用水平不高。4)本文利用两维图论聚类算法,基于适宜性评价结果,再结合实际的空间利用特征及城乡规划,将陈贵镇“三生”空间分为5个区域。I区为农业生产核心区,该区域农业生产空间面积较大且较为聚集;II区为乡镇发展主导区及生活空间核心区,引领着陈贵镇未来城乡一体化发展的方向;III区为综合发展潜力区,空间存在着多种国土开发利用价值;IV区为生态重点保护区,需要着重协调工矿生产空间与生态空间的协调发展;V区为生态农业旅游发展区,可利用生态农业带动生态旅游业的发展。

Abstract: Study on suitability division of “production-living-ecology” (PLE) space microscopically can provide references for town-level land planning and consolidation. This paper, based on a case of Chengui town, Daye city, Hubei province as a ore-crop compound area, establishes an evaluation index system of its PLE space suitability, and uses 2-dimensional graphic clustering to evaluate its suitability and division of “production-living-ecology” space in Chengui town. Chengui town's suitable PLE space has two blocks, one sparsely distributing along Chengui village, and the other concentrating in Tiantaishan district. Unsuitable PLE space is mainly distributing in the south and northeast, with other scattering as small blocks. From the perspective of the spatial suitability of the “production-living-ecology” in the village area of Chengui town,villages classified as suitable have a balanced development among PLE spaces, near governmental planning objectives in intensive production space, friendly living space and green ecological space. Mining activities play a influential role on its suitability of PLE space, adversely impacting ecological space, agricultural production and non-mining production, so decreasing social benefits of the ore-crop compound area, and possibly resulting in a lower overall spatial use level. This paper uses 2-dimensional graphic clustering to divide Chengui town's PLE space into 5 regions according to suitability evaluation and actual spatial use and rural-urban planning. Region I is the agricultural core zone concentrating with large areas of agricultural production. Region II is living core zone leading the future rural-urban integration. Region III is comprehensive developing potential zone with variety of land uses. Region IV is the core ecological protection area needing a coordinated development between mining space and ecological space. Region V is the ecological agricultural tourism are focusing on ecological agriculture directing ecological tourism.

Key words: 2-dimensional graphic clustering, ore-crop compound area, “production-living-ecology”space, suitability division
