西双版纳茶林及橡胶林区鸟类调查

1983年5—7月,作者对云南省西双版纳的勐海、勐养和勐腊三个地区的茶林和橡胶林区的鸟类区系组成情况进行了调查,其结果若与开发前（郑作新、郑宝赉,1961,1962;A.И.伊万诺夫,1961）的记录对照,在季节时间上有所不同,但该地区的热带雨林和季雨林被开垦种植为茶林、橡胶林及其它经济作物之后,反映出各林区现在的繁殖鸟种类减少很多,鸟类区系组成情况有显著的变化。

INVESTIGATION ON THE BIRDS OF CULTIVATED LAND OF TEA TREES AND RUBBER TREES IN XISHUANGBANNA, YUNNAN PROVINCE

In order to study the variations of Avifauna components after the cultivation of the natural tropical rain-forest and seasonal rain-forest in May-July 1983, the writets investigated and collected the birds species at Meng hai, Meng yang and Meng la of Xishuangbanna, Yunnan Province. During this survey we recorded 89 species of breeding birds (12 are summer visitors, 77 residents), belonging to 67 genera, 32 families and 4 subfamilies, 12 orders. Twenty five years ago, there were 198 species of breeding birds reported by Zheng Tso-hsin.Zheng Bao-lai (1961, 1962) and A. H. MsaHOB (1961) at these places, Comparing our results with that they published we find only 45% of the breeding birds being remained. We think that the main cause for the great reduction of bird species in the cultivated districts or areas in Xishuangbanna is the substitution of rubber forest and tea forest for the natural tropical rain-forest and seasonal rainforest resulting in the loss of habitat and food. Thus we strongly suggest that construction within the natural reserve be controlled and hunting prohibited. We must also strengthen the propagation of loving and protecting of birds.
