北京地区的兽类区系及生态地理特征

北京地区的兽类,解放前有些调查记录(Allen 1938、1940),解放后也有一些零星的调查报道(Ellerman 1951,李汝琪;1956,北京师范大学生物系动物教研组,1960;伊佩衡,1964;北京大学生物系,1964等),但工作均较局部,更缺乏生态学方面的材料。

CHARACTERISTICS OF MAMMAL FAUNA AND ECO-GEOGRAPHY IN BEIJING AREA

Studies on the mammal ecology had been undertaken from May, 1982 to July, 1983 in Beijing. This paper deals with the characteristics of mammal fauna and eco-geography only.Beijing is located in the northwest of North-China plain, and its mountain area accounts for 62%.The following aspects have been attained. 1. Characteristics of mammal fauna (1) The species are poor in Beijing and unevenly distributed, with a total number of 41 species.(2 ) None of the species are out of the ordinary. The whole fauna is a mixture of the fauna of South China, North China, Inner Mogolia-Xin-jiang and the Pacific monsoon area.( 3 ) Human's economic activities have led to distinct changes of the fauna.2. Characteristics of the Eco-geographyAccording to the composition character of the rodent community and environment, eight types of Eco-geography can be formed.3. The mammal resourses, natural protection as well as rodent damage and population growth were discussed.
