A spatially explicit landscape model LANDIS was applied to simulate the forest landscape changes under four management alternatives (no cutting, clear cutting, selective cutting I and II) in Youhao Forestry Bureau located in Small Xing' an Mountain from 2000 to 2200. The outcomes from LANDIS were combined with a landscape-level habitat suitability index (HSI) model in a GIS environment to assess Sciurus vulgaris habitat quality. The results showed that the increase of suitable habitat area and the decrease of marginally suitable area were the fastest under no cutting scenario, and the slowest under clear cutting scenario. Suitable habitat area increased faster while marginally suitable area decreased more slowly under selective cutting I scenario than under selective cutting II. Overall, the optimal management alternative of S. vulgaris habitat was in the sequence of no cutting, selective cutting I, selective cutting II, and clear cutting.
应用一个空间明确的景观模型LANDIS来模拟位于小兴安岭的友好林业局在2000年至2200年期间四种经营方案（不砍伐、皆伐、择伐I和择伐II）下的森林景观变化。在地理信息系统（GIS）环境中，将LANDIS的结果与景观水平的栖息地适宜性指数（HSI）模型相结合，以评估松鼠（Sciurus vulgaris）的栖息地质量。结果表明，在不砍伐方案下，适宜栖息地面积增加和边缘适宜面积减少的速度最快，在皆伐方案下最慢。与择伐II相比，择伐I方案下适宜栖息地面积增加更快，边缘适宜面积减少更慢。总体而言，松鼠栖息地的最佳经营方案顺序为不砍伐、择伐I、择伐II、皆伐。
