摘　　要：量化居民点空间分布离散度并探索其与农村经济指标的关联关系,以期为＂整村推进＂扶贫开发规划的实施提供指导意见。以国家扶贫重点县——鹤峰县为研究区,以行政村为评价单元,分别从人文和自然角度引用离散度综合指数（DCI）和景观综合指数（LCI）结合空间探索性分析方法,对比分析鹤峰县居民点空间分布的离散特点,并采用线性回归模型和空间滞后回归模型剖析鹤峰县整体及不同自然与经济条件下离散度与农民人均纯收入之间的相互影响关系。研究结果表明：1）整体上,DCI与LCI均存在空间聚集效应,但两者空间分布特征存在差异,DCI评价结果介于0.59~4.56,LCI评价结果介于0.14~2.61,DCI可以更好地反映离散度。2）通过空间滞后回归模型对DCI与农民人均纯收入分析,得到两者间呈明显相关关系。3）DCI与道路密度、经济圈层、坡度均存在相关关系,同时反映收入变化趋势;LCI在经济圈层等级下未表现出此特征。对于＂整村推进＂扶贫项目的实施,既要重视道路等人文要素的影响,也要考虑行政村之间的联系。Quantifying the dispersion of settlement spatial distribution and exploring the relationship between the distribution index with rural economic indicators,so as to provide guidance to ＂the whole village poverty alleviation and development plan＂ implementation.In this paper,with Hefeng County as the research area and administrative village as the evaluation unit,combined with the spatial exploratory analysis method,the characteristic of residential spatial distribution dispersion in Hefeng County is analyzed from the angle of humanity and nature.And using linear regression model and spatial lag regression model,the interaction between the village′s dispersion with per capita income on different natural and economic conditions is analyzed in detail.The result shows that：the dispersion evaluation results of DCI and LCI are within the scope of 0.59~4.56 and 0.14~2.61 respectively.With the higher road density,the closer distance to economic center,the smaller terrain,the dispersion index is smaller and residential space distribution is more intensive,the regional economy is more developed.In planning the layout of the village settlements,we should comprehensively consider the influence of many factors,and combine the influence of human factors such as the road.
