摘要
研究了血雉目前的分布范围以及分布现状.由于血雉的分布受海拔、气侯、植被以及人类经济活动等因素的影响,使血雉呈现出断续的相对集中的种群分布状态.所以,目前的分布范围相比60年代和70年代要小,这种分布区的相应缩小与人类经济活动而影响到生态环境的改变有着密切的关系.
The distribution range and the present situation of blood—pheasant are studies. The results of the study show that the distribution of blood—pheasant is influenced mainly by factors of elevation (height above sea level), climates and vegetation as well as human activity etc. All of these factors let blood—pheasant distributed intermittently. So the distribution range of blood—pheasant at present is smaller than one divided by Zheng Zuoxin in 1976 and 1978. There are close relations between the corresponding shrinking of distribution range and the changes of ecological environment caused by human beings' economic activities.
