碧塔海流域生态旅游景观类型及其空间组合特点

碧塔海独特的高原自然地理环境和轻微的人类活动长期综合作用营造了高品位、多类型的自然生态旅游景观。按自然地域分异、景观内部特征的相对一致性和主导因素三个原则将碧塔海流域内的自然生态旅游景观划分为3个景观类、5个景观亚类和15个景观型。根据空间尺度的大小,探析了三个景观等级层次的空间组合特点及其相互间的生态关系,为生态旅游规划,科考旅游声线设计及景区生态管理提供了科学依据。

CLASSIFICATION AND SPATIAL COMBINATION LAW OFTHE ECOTOURISM LANDSCAPE TAPES IN THE BITA LAKE BASIN OF NORTHWEST YUNNAN

The ecotourism landscape of Bita Lake Basin is very tasteful and diverse,it is constructed in the course of long-term synthetical use of distinctive natural plateau environment and slight human activity The landscape features is of representative in south-western Yunnan on the basis of heterogeneity and hierarchy of landcape ecological system,the landscape classification system of Bita Lake is presented In our plan, natural region disparities,relative consistency of inherent characterics of landscape and key factor are considered as classification principle Ecotourism landscape units at different level are adopted 3 landscape types, 5 subtypes and 15 landscape units are divided According to the size of space scale,the spatial combination features of landscape and their ecological relation between landscapes are researched qualitatively The above studies provide important basis for the planning, the design of scientific explanation route and the ecological management of Bita Lake ecotourism spot
