塔里木河中游塔里木马鹿种群数量及其栖息地现状的初步分析

为了查明塔里木河中游野生塔里木马鹿种群数量及栖息地资源,2006年10月1～15日,采用截线抽样法和地理信息系统相结合,对塔里木马鹿种群及其栖息地进行了研究.结果表明,现有野生种群数量大约在21～71头,集中分布在离人类干扰比较远的依明且克和托胡拉克阔坦一带.同时采用地理信息系统分析方法对研究地区的LANDSAT TM 遥感影像进行了监督分类处理,把研究区影像土地覆被分成了农田、水体、高密度林地、中密度林地、低密度林地、草地、沙漠、盐碱地、荒漠等9类型.其中塔里木马鹿主要分布在中,高覆盖度胡杨林、红柳灌丛和胡杨红柳混交林带中.同时根据在不同类型栖息地中马鹿粪便、卧迹、足迹的出现频率并结合地理信息系统分析结果,把研究地区生境划分为4种适宜栖息地等级.其中不适宜区占62.6;;较差区占3.76;;适宜区占3.38;;非常适宜区占30.23;.

Preliminary Study of the Current Population Density and Habitat Characteristics of Tarim Red Deer (Cervus elaphus) in Middle Reaches of Tarim River

In order to investigate the current population density and habitat availability of the Tarim red deer in Tarim popular tree natural protection area,the Line transwct method and geographical information system were used to study Tarim red deer population on October 1 to 15,2006 in popular tree natural protection area in Xinjiang.The result showed that the current population density of the Tarim red deer are between the 21-71 head,and mainly distributed in the Yimingqieke and Tuohulakeqaodan areas.At the same time,the study area with nine land cover types are classified as follows:farmland,water body,high coverage vegetation,middle coverage vegetation,low coverage vegetation,desert,sand dune,soil with salt deposit.Among them the Tarim red deer was mainly distributed in the area with high and middle coverage popular trees and Tamarix bushes.The living environment in the study area was divided into four suitability classes based on the activity marks like the pellet group,lying marks,footmarks and geographical information system analysis results.Results showed that the non-suitable area occupies 62.6% of the study area,less suitable area 3.76%,suitable area 3.38% and the most suitable area 30.23% respectively.
