西双版纳勐宋地区鸟类多样性及人地关系初步研究

地理环境独特的西双版纳部分地区尚存不少资源丰盛，反映山区民族自然经济人地关系模式，鸟类多样性敏感地显示其相关性。在边远山区，必须全面了解人地关系的历史性及其生态过程、注意发扬当地持续管理林地的经验，不断协调人地关系，生物多样性保护，持续发展才会有更好的前景。

A PRELIMINARY STUDY ON BIRD DIVERSITY ANDMAN-LAND RELATION IN MENGSONG HANI ETHNICREGION, XISHUANGBANNA, YUNNAN

In a Hani ethnic region of Mengsong area, Xishuangbanna, Yunnan, near Burmerse border, there are traditional practices of agriforestry, which 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 Hani people had strong religious and cultural prohibitions a-gainst overcutting and overhunting. They can also manage natural environment and make ecotone habitats to maintain biological diversity. Bird diversity in different areas was obtained, a great deal of biodiversity exists in the place where people have lived for many generations, using the resources of their environment in a sustainable manner. Local people were practicing a traditional way of life in the land, the Hani people keep some areas as traditional conserving forests, in which the natural resources were selectively used with regeneration abilities, they are also as better habitats for birds. The present people are exploiting Mengsong area, the society is changing rapidly as it encounters outside influences, and there are often sharp differences between the older and younger generations. We should pay more attention to the ecological principle of man and land from the traditional practices.
