为了评价农村居民点的景观特征,探讨农村居民点综合景观状况和理论整理潜力之间的关系.以2008年成都市彭州熙玉村的农村居民点为研究对象,采用景观生态学方法,从农村居民点规模、用地、分布及形状的角度构建了农村居民点景观特征评价指标体系,引入了综合景观状况指数,并采用主成分分析法,分析了综合景观状况与景观指数对综合景观状况的贡献.采用人均建设用地标准测算了农村居民点整理的理论潜力,并探讨了综合景观指数与理论潜力之间的关系.结果表明:熙玉村农村居民点用地比例较高,并且密集区比较多,农村居民点的疏密程度受海拔与坡度的影响比较大；大部分小组的农村居民点规模较大,并且居民点之间衔接比较紧凑,居民点形状比较规整.大规模的集中居住区和散居户或小规模的居住区同时存在；整体景观状况是综合的,是多个景观指数在特定区域内按照一定的贡献率共同作用的结果.要提高研究区的综合景观状况,就得从农村居民点的分布和形状着手;综合景观指数与理论整理潜力的相关性比较强,二者关系的趋势线呈抛物线状,在农村居民点综合景观指数比较高的区域,其理论整理潜力相对较低.%In order to appraise landscape traits of rural residential land and analyze the relationship between integrated landscape index and theory potentiality, the paper took the rural residential land of Xiyu village as the research object, and constructed the appraisal index system from the rural residential land scale, land-use, distribution and shape with the method of landscape ecology. And integrated landscape trait and the contribution of sole landscape index to the integrated landscape trait was analyzed based on integrated landscape index and principal component analysis. The results showed that the proportion of land use was high and many groups were in the intensive areas, and the extent of intensiveness was impacted greatly by altitude and slope. The scales of many groups were large and the connection was compact, the shape was neat. The large residential land coexisted with small and scattered residential land. Integrated landscape trait was influenced by some landscape traits following the contribution ratio, it was important to develop the distribution and shape traits in order to improve the integrated landscape trait. The relationship was obvious between integrated landscape index and theory potentiality, which took on the trend of Parabola, that was, the bigger of integrated landscape index, the lower of the theory potentiality.
