摘　　要：以昌黎黄金海岸国家级自然保护区2000年与2010年的土地利用数据为基础,运用基于空间的InVEST模型生境质量评价模块对研究区域的生态环境质量进行评价,并基于地理信息系统空间统计方法对生境退化度、生境质量和生境稀缺性的空间分布特征及其动态变化进行定量分析。结果表明,十年间保护区生境退化度增大;生境质量虽有所下降,但总体质量仍处于较高水平;生境稀缺性分值大部分较低,说明区内生境的稳定性整体上较好,土地利用变化趋于缓和。Assessment on habitat quality of Changli Golden Coast National Nature Reserve has been done based on a spatial model of In VEST using the 2000 and 2010 landuse data as basic data source. Using GIS spatial statistical methods,the spatial distribution and dynamic change were analyzed quantitatively. The results show that during the ten years,habitat degradation increased and habitat quality decreased,but the entire quality was still in a higher level. Values of habitat rarity were low in most of the areas and this indicated that the habitat stability was good in overall and landuse change was gentle.
