三峡库区农村居民点集约用地模式研究——以重庆市长寿区为例

Intensive land use patterns of rural settlement in Three Gorges Reservoir Area——A case study in Changshou District of Chongqing

以三峡库区重庆市长寿区为例,在建立包括自然环境、经济社会、用地状况等因素在内的农村居民点整理分区指标体系的基础上,通过层次分析法(AHP)确立了各评价指标权重,以各街镇为评价单元,依据综合评价指数将长寿区农村居民点划分为Ⅰ级优化整理区、Ⅱ级重点整理区、Ⅲ级优先整理区。结合不同整理分区特征,探索社区移民型、城乡统筹型、散居移民型等3种农村居民点集约用地模式,并实施差别化的集约用地模式。Ⅰ级优化整理区主要采取散居移民型,Ⅱ级地重点整理区主要采用城乡统筹型,Ⅲ级优先整理区主要采取社区移民型。在长寿区分别建设了社区移民型、城乡统筹型、散居移民型3个农村移民住宅区建设科技示范工程,通过居民点整理,引导农民统一居住,提高了土地节约集约利用水平。

We set up an integrated indicator system of rural settlement＇ s consolidation zoning in Changshou District of Chongqing, an representative area in Three Gorges Reservoir Area of China. This integrated indicator system consists of three subsystems： natural environment, society-economy, and land status. The indicators＇ weights are determined by analytic hierarchy process （AHP）. And then, rural settlement in Changshou has been divided into three main consolidation zones according to each town＇s comprehensive evaluation index. The zones include Ⅰ -level optimized consolidation area, Ⅱ-level emphasized consolidation area, and Ⅲ-level prioritized consolidation area. Combined with different consolidation zones＇ characteristics, we discuss three intensive land use pattern of rural settlement, including the type of community immigration, the type of urban-rural harmony, and the type of scattered immigration, respectively. Three consolidation zones should take the differential models： （1）Ⅰ -level optimized consolidation area： it should adopt the intensive land use pattern of scattered immigration; （2） Ⅱ -level emphasized consolidation area： it is suited to choose the intensive land use pattern of urban-rural harmony; （3）m-level prioritized consolidation area： the intensive land use pattern of community immigration should be selected. According to the intensive land use patterns, we built three rural migrant residential technology demonstration projects in Changshou District, which involved the type of community immigration, the type of urban-rural harmony, and the type of scattered immigration. The demonstration projects improved the level of land saving and intensive use by settlement＇s consolidation and peasant＇s unity residence.
