四川大熊猫国家公园区域景观生态系统特征与国家公园适宜性研究

Study on Regional Landscape Ecosystem Characteristics and Suitability of National Park in Sichuan Giant Panda National Park

  • 摘要: 基于景观生态学理论,对四川省大熊猫国家公园试点区域所在的岷山中高山区域土地利用类型、植被类型和区域资源特点等数据进行了空间叠加分析,通过查阅相关资料文献,并借助景观格局和景观类型2个尺度的景观指数,对研究区域资源的国家代表性、生态系统完整性进行了研究;通过对该区域内人为干扰活动区域和国有土地比例等的研究,对区域生态系统原真性和国家公园管理可行性进行了研究。结果表明该区域国家代表性强,自然生态系统完整性和原真性较高,国有土地和保护地面积均接近80%,具有建设国家公园的管理可行性,但研究区域景观斑块数量多,大熊猫主要栖息地类型亚高山常绿针叶林,平均斑块面积不高,农耕活动是区域内最主要的人为干扰活动。

     

    Abstract: Based on the theory of landscape ecology, the data of land use types, vegetation types and regional resource characteristics in the middle and high mountain region of Minshan Mountain, where the pilot area of Sichuan Giant Panda National Park is located, were spatially superimposed and analyzed. By consulting relevant information and literature, and with the help of landscape index of landscape pattern and landscape type, the national representativeness and ecosystem integrity of regional resources were studied. Based on the study of the area of human disturbance and the proportion of state-owned land, the authenticity of regional ecosystem and the feasibility of national park management were studied. The results showed that the countries in this region were highly representative, the integrity and authenticity of the ecosystem were high, and the area of state-owned land and protected land was close to 80%, and it is feasible to build the national park. However, there are a large number of landscape patches the study area, and the main habitat type of giant pandas was subalpine evergreen coniferous forest, with a low average patch area. Farming activities were the most important human disturbance activities in the region.
