摘要以黑龙江省1773个贫困村为研究对象，运用最邻近指数、核密度、空间自相关、数据叠加等空间分析技术，从数量规模、空间分布模式、垂直分布特征等方面分析贫困村空间分布特征。结果表明：黑龙江省贫困村个数占行政村总量的19．68％，贫困村面积占行政区土地总面积的7．69％，地区（市）间贫困村个数及面积比例存在显著差异；贫困村在国贫县、省贫县和非贫县中个数比率分别为47．23％、35．71％和8．19％，面积比例分别为25．65％、24．56％和2．38％；贫困村在不同尺度上的集聚特征均比较明显，在国贫县、省贫县、非贫县内集聚程度依次降低；贫困村之间存在较强的空间依赖性，在黑龙江省的西部和东部地区分别呈现出一个核心集聚片区和一个相对集中的条带区；64．12％的贫困村分布在高程为200m以下的平原区，其中有一半的贫困村分布在150～200m的高程带上。 Fully understanding the spatial distribution pattern of poverty villages is the basis for formulating regional poverty alleviation strategies and eliminating regional poverty. In this paper, 1 773 poverty villages in Heilongjiang Province were taken as the research object. The quantity, spatial distribution pattern and vertical distribution characteristics of poverty villages were analyzed by using a nearest neighbor index, the kernel density, spatial autocorrelation, data superposition and other spatial analysis techniques. The results show that the number of poverty villages in Heilong：jiang accounts for 19.68% of the total amount of administrative villages, and the area of the poverty villages accounts for 7.69% of the total land area of the administrative region. There are significant differences in the ratio of number and area of poverty villages between different districts. The number proportion of poverty villages in state poverty counties, provincial poverty counties and non-poverty counties respectively are 47.23%, 35.71% and 8.19%, and the area proportion are respectively 25.65%, 24.56% and 2.38%. The concentration characteristics of poverty villages are all obvious at different scales, furthermore,the concentration degree of poverty villages is gradually decreasing in state poverty counties, provincial poverty counties and non-poverty counties. There is a strong spatial dependence between the poverty villages. A core concentration area has been found in the west area of Heilongjiang Province, and a relatively concentrated strip in the eastem region. Besides, 64.12% of the poverty villages are distributed in the plain area below 200 meters, of which half of the poverty villages are distributed on the elevation belt of 150-200 meters.
