Abstract: Rural residential land is one of the major landscapes for rural settlement. Spatially, the newly-construction or reconstruction for rural residential land depends on its interaction of competitive control and coverage with interior and exterior environment. Under the background of accelerating urbanization in China, rural residential land has been increasing rather than decreasing. At the same time, the impact of its spatial layout and expansion on the natural ecological environment and feedback has not been considered enough. Based on the relevant theories and methods of landscape ecological pattern, this paper uses the minimum cumulative resistance model, and takes Dujiangyan as an example to evaluate and analyze the ecological suitability of rural residential land sites. The results showed that: (1) For the past ten years, the spatial distribution of ecological suitability zoning in the study area was relatively concentrated, with shrink in divisions of relative high and highest levels of ecological suitability, while evident expansion in divisions that of relative low and lowest levels. These great contrasts indicated that the impact of human activities on the local landscape pattern was increasing. (2) The dynamic changes of ecological suitability varied within different time periods, in lowest level of ecological suitability area, the quantities and areas of rural residential land kept increasing, while in that of moderate and above levels, the quantities and areas showed increase firstly and then decline. (3) The ecological suitability of residential land was changing continuously, with 559.39 hm2 from 2005 to 2010 and 781.11 hm2 from 2010 to 2015 respectively. The results have extensive practical value in strengthening protection of local significant ecological landscape unions, coordinating the contradiction between human and land, and human and nature, improving the utilization efficiency of rural land resource, making plans of rural constructive development.
