青海省循化县孟达林区的鸟类和鸟类资源

THE EAUNA,CONSERVATION AND MANAGEMNENT oF AVIANRESOURCE OF MENGDA FORESTS OF XUNHUA COUNTY,QINGHAI.

笔者于1983年7—8月、1988年10月对孟达林区的鸟类进行了考察,共录得鸟类64种,其中繁殖鸟62种,占总数的96.8％,古北界41种。华北区、青藏区、蒙新区和横断山脉区系成份分布在此,区系成份复杂。由于特殊的地理位置,致使“边缘效应”显著,无论从鸟的种类或数量都高于邻近任何地区。根据植被、鸟类的分布将栖息地划分为:阶地农田、松栎桦林带、高山灌丛草甸三个类型。该地区鸟类资源丰富.应保护好栖息环境、禁止偷猎、采用补食补饲方法和开展进一步科学研究工作。

Sixty-four species of birds were collected and observed in Mengda forest of Qinghai from July to August of 1983 and October of 1988.Among them 41 species belong to Palearctic and 62 kinds of birds nest here.Birds belong to the avi fauna of North China,Qinghai-Xizang, Mongol-Xinjiang and Hengduan Mountain all can be found there.The avian species diversity is richer and population sizes of birds are more abundent than the adjacent area's because of “Boundary effection” resulted from the geographic location of this area.Habits can be divided into three formes according to vegetation,avian distribution:Terrace of agricultural tield;Coniferous and broad-leaf forest dominated by Pinus sp.,Betula sp.,and Quercus sp.,Alpine shrub and meadow;Conservate suggestion commended by the auters are:protecting birds from both disater of habitat distruction and poaching as well as applying food for birds.Scientific research should be taken in the recent future.
