褐马鸡种群结构的研究

STUDY OF POPULATION STRUCTURE OF BROWN EARED PHEASANT

本文作者于1982——1988年,在山西庞泉沟国家级自然保护区对褐马鸡(Crossoptilon mantchuricum)种群结构进行了研究,其内容包括了种群性比结构,种群年龄组成。由于该鸟属珍稀濒危物种,不可从野外采集标本收集有关资料,故种群结构的资料和数据,是通过直接剖检观察人工饲养、野外自然死亡者和争偶斗死者得到的。

From 1982 to 1988,the authors of this article studied the population structure of Brown Eared Pheasant at Pang Quan ditch, the nature sanctuary of the national level in Shan xi province. The research content consists of the population sex ratio strcture and the composition of population age. Because of this bird belongs to the rare species,the sample and the date of this kind of birds can not be collected in the field, which can be achieved not only by the artificial feeding,the nature dead-bird of the fild and struggle dead,but also by direct dissection and observation.
