摘　　要：以西藏自治区现有6种类型共102处自然保护地为研究对象,采用地理集中指数、不平衡指数、最邻近点指数和核密度估计的方法对自然保护地空间特征进行定性和定量分析研究。结果表明,西藏自治区自然保护地具有聚集分布的特点,交叉重叠区域呈藏西阿里高原山地区、藏东南高山深谷区交叉重叠面积大,藏中雅江流域交叉重叠数量多的特点,在重叠类型上,自然保护区与自然公园的重叠是最为普遍的重叠类型。对西藏自治区自然保护地空间分布格局评价结果,生态区位重要,保护价值高,总体布局基本合理,仍有优化空间,提出推进国家公园建设,完善保护体系,优化空间布局等建议。By studying a total of 102 natural protected areas of 6 types in Xizang Autonomous Region,qualitative and quantitative analysis on the spatial characteristics of natural protected areas were conducted by using the methods of geographic concentration index,imbalance index,nearest point index and kernel density estimation.The results showed that the natural protected areas in Xizang Autonomous Region were characterized by aggregated distribution.The intersection and overlapping areas showed the characteristics of large intersection and overlapping areas in the Ali Plateau mountain areas in western Xizang,high mountains and deep valleys areas in southeastern Xizang,and a large number of intersection and overlapping areas in the Yajiang River Basin in central Xizang.In terms of overlapping types,the overlap between nature reserves and nature parks was the most common type of overlap.According to the evaluation results of the spatial distribution of natural protected areas in Xizang Autonomous Region,the ecological location was important,the protection value was high,the overall layout was basically reasonable,and there was still room for optimization.Suggestions were put forward to promote the construction of national parks,improve the protection system,and optimize the spatial layout.
