哈尔滨市阿城区农村居民点景观格局与空间分布特征分析

Analysis on Characteristics of Landscape Pattern and Spatial Distribution of Rural Residential Areas in ACheng District of Harbin City

以黑龙江省哈尔滨市阿城区农村居民点为研究对象,利用2008年第二次土地调查矢量数据和地形图等数据,采用景观指数法、相关分析法、缓冲区分析法等多种方法,应用ArcGIS软件,分析了阿城区农村居民点用地规模与布局特征及影响因素。结论表明:①阿城区农村居民点总体上属于集群分布,数量多,规模较小,但个体差异较大;②农村居民点分布主要受地形、交通、经济状况影响,多分布在公路、河流两旁。西北平原区农村居民点数量多,规模大。东南部农村居民点数量少,规模也较小;③整个阿城区景观格局稳定性较弱,应加强生态建设。

In this study, Rural residential Areas in ACheng district are studied, with the vector data of 2008 and topographic map, Using the landscape indices, correlation analysis, buffer analysis and other analysis method, Based on the theory of computational geometry, AreGIS software was applied to analysis the scale, layout character and influencing factors of rural residential areas in ACheng district. Conclusion is that the whole rural residential areas belongs to the cluster distribution, smaller, but large individual differences; rural residential areas distribution are effect by topography, transport factors and economic conditions. They almost distribute on both sides of roads or river.The stability of the entire city landscape is weak, Ecological construction should strengthen.
