FOREST LANDSCAPE AND BIRD DIVERSITY IN MOUNTAIN REGION, XISHUANGBANNA, YUNNAN

Healthy forest landscapes into degraded land is a major impact of human on the natural environment,which is poing a great threat to biodiversity. Birds are the most dynamic and susceptible for the forest structure,they are also more observable of the animals in the forest. We studied the relationship between forest landscaps and birds in mountain regions of Xishuangbanna, Yunnan province.The forest landscape of Jinuo ethnic region is changing from rapid influence of human,as well as the bird diversity is reducing. The comparative study from a Hani ethnic region of Mengsong area, Xishuanghanna, near Burmerse border, there are also traditional practices of agriforestry. The traditional practices are dynamic adaptations to local geographic environment,and social economic conditions. This system works well and does not degrade the environment as long as human population density is low and there is abundant forest land. The Ham people had strong religious and cultural prohibitions against cutting the forest and overhunting,They can also manage the environment and made ecotone habitats to maintain bioligical diversity as shown by the traditional agroecosystems and forests of the Mengsong area. A greast deal of biodiversity exists in the place where people have lived for many generations, using the resources of their environment in a sustainable manner. Loacal people was practicing a traditional way of life in the land,with relatively little outside influence. Bird diversity in different habitatS was obtained from old fallow fields. Ham people keep some areas as traditional conserving forests,in which the natural resources were selective used with regeneration abilities, they are also as better landscape.Considering bird diversity and forest landscape of mountain area, taking into account both economic and ecological benefits, which relate to land use and landscape planning. Biodiversity conservation, resource management and policy making should poy more attention to the best interconnection of landscapes.
