【摘要】 以大熊猫国家公园邛崃山-大相岭片区1995—2018年5期的遥感影像及土地利用数据为基础，运用形态学空间格局分析、转移矩阵及动态度模型、景观格局指数等方法对比分析研究区各时期的景观格局状况和破碎化程度。结果表明：（1）研究区GI网络结构要素以核心区为主，其他要素分布较为零散；（2）林地与草地面积占比超过96%，是研究区两大优势景观类型，除草地与未利用地面积总体缩减外，其余景观类型面积总体增加；（3）各时间段景观类型转移主要发生在林地与草地、耕地之间，2007—2013年建设用地动态度最大；（4）由景观格局指数结果可知，斑块类型水平上，6大景观类型破碎化程度加剧，且林地和草地的优势度有所削弱；景观水平上，研究区内部景观破碎度、多样性、形状复杂程度总体升高，蔓延度与聚集度总体降低，整体连通性较差。最后，针对以上问题提出景观格局相关优化建议，研究结果可为大熊猫国家公园邛崃山-大相岭片区的土地利用管理及生态环境保护提供数据支持与理论参考。更多还原

【Abstract】 Based on the remote sensing images and land use data of Qionglai Mountain-Daxiangling area in Giant Panda National Park from 1995 to 2018, the landscape pattern status and fragmentation degree of each period in the study area were comparatively analyzed by using morphological spatial pattern analysis, transition matrix and dynamic degree model, landscape pattern index and other methods. The results showed that:(1) The structural elements of GI network in the study area were mainly the core area, and other elements were scattered;(2) The woodland and grassland accounted for more than 96% of the total area, which were the two dominant landscape types in the study area. Except for the overall reduction of grassland and unused land, the area of other landscape types had generally increased.(3)The shift of landscape types in different periods mainly occurred between woodland, grassland and cultivated land, and the dynamic change of construction land was the largest from 2007 to 2013.(4) According to the results of the landscape pattern index, at the patch type level, the fragmentation degree of the six major landscape types increased,and the dominance of woodland and grassland were decreased. On the landscape level, the fragmentation, diversity and shape complexity of the landscape in the study area was generally increased, while the degree of spread and aggregation were generally reduced and the overall connectivity was poor. Finally, aiming at the above problems, some suggestions on landscape pattern optimization were put forward. The research can provide data support and theoretical reference for the ecological environmental protection and management of the Qionglai Mountain-Daxiangling area of the Giant Panda National Park.更多还原
