摘要
采用GIS技术,结合实地考察数据和历史数据,通过对信息加工与处理,对1973-2003年间塔里木胡杨林自然保护区马鹿塔里木亚种(Cervus elaphus yarkandensis)分布区的生境动态情况进行了研究,同时对影响塔里木马鹿栖息地变化的主要因素进行了分析。结果表明,自1973-2003年在塔里木胡杨林自然保护区中各种生境类型的变化比较显著,其中(1)水资源严重缺乏,水量剧烈减少,水域面积大幅缩小(2)沙漠面积和低盖度植被面积略有减少,高盖度植被面积减少强烈,保护区内耕地面积快速增加,荒漠化趋势明显,总体上马鹿塔里木亚种分布区的各种生境类型处于变化状态,栖息地环境趋向恶化。
In this paper, the habitat dynamics characteristics of red deer Tarim subspecies were analyzed by using geographical information system （GIS） to assess the factors that mainly impact the red deer habitats in populus natural reservation area in Xinjiang ,China based on the spot investigation and historical data from 1973 to 2003. The results showed that from 1973 to 2003, in the natural reservation area the habitat types suitable for the red deer Tarim subspecies distribution have decreased. Among them （1） Water resource and area were diminishing heavily, though state has strengthened management of water resource, the effect is not so obvious. （2） The surface of the desertification area and the vegetation of low coverage have been decreased slowly, but the vegetation has highly coverage have been decreased rapidly, at the same time the surface of the cultivated lands have been rapidly increased, desertification is in process. The mainly reason make change the habitat pattern are different human activities.
