Abstract塔里木河流域荒漠河岸林具有重要的生态、经济和社会效益.本文以塔里木河干流的荒漠河岸林系统为对象,借助于卫星遥感、GIS等技术,研究塔里木河干流区各河段天然植被分布特征,应用缓冲区梯度分析方法对林地分布结构和生态需水进行分析.结果表明:(1)塔里木河干流区天然植被面积为146.1×104 hm2,占研究区总面积的35.18%;北岸天然植被面积较南岸多46.34×104 hm2.(2)塔里木河干流区荒漠河岸林分布随距离河道的增加呈波动下降趋势.在影响保护带、基本保护带和重点保护带下,天然植被保护范围分别为4.7~30.1 km、2.2~24.2 km和0.8~12.3 km.(3)塔里木河干流区天然植被总的生态需水量为21.932×108 m3,在重点保护带、基本保护带和影响保护带下,生态需水量分别为9.56×108 m3、14.97×108 m3和19.08×108 m3.根据荒漠河岸林的分布特征和保护目标,对塔里木河干流用水作统一规划和协调是符合实际的生态治理措施.
