塔里木马鹿(Cervus elaphus yarkandensis)且末种群栖息地动态变化分析

Study on Dynamic Habitat Availability of Qarqan Population of Tarim Red Deer(Cervus elaphus yarkandensis)

本文采用地理信息系统(GIS)分析方法对1972—2001年车尔臣河中下流域马鹿(Cervus elaphusyarkandensis)栖息地变化进行了研究.结果表明:车尔臣河流域马鹿栖息地从1972—2001年呈现下降趋势,1972年的栖息地总面积为2 063.585 km2,其中适宜栖息地有869.894 km2,1990年的栖息地总面积为1 916.298km2,其中适宜栖息地有466.848 km2,2001年的栖息地总面积为1 758.485 km2,其中适宜栖息地有222.786km2.车尔臣河中下流域马鹿现正遭受栖息地质量退缩和适宜栖息地面积不断减少的双重影响.

We used a GIS model to study on the habitat of Tarim red deer in Qarqan River, and Evaluated the variety dynamic state of red deer habitat form 1972 to 2001. The result is that the area of living habitat declined. The total area is 2063. 585 km^2,among that the fitting living area is 869. 894km^2 in 1972. There are 1916. 298 km^2 in the total area in 1990, and among that the suited habitat is 466. 848km2. In the year of 2001,there were only 1758. 485 km^2 in the total area, and among that is 222. 786km^2 of the suitability living habitat. Red deer in the Qarqan River area suffered from the shrink of habitat and the continuous reduction of the fitting living environment.
