摘要: 近十几年来,塔里木河下游地区由于上、中游用水量大幅度增加,造成过镜水量逐渐减少以致于断流,生态条件趋于恶化,使得沙漠化过程加剧。-些专家学者就此进行了广泛和有益的探讨。本文在此基础上,选择塔里木河下游的阿拉干这-典型地区,通过野外考察(1985年5月进行)和不同时期航空相片的判读、量算,针对地表形态的变化和其各种类型的动态分配,来说明该地区的沙漠化过程;并试图运用计量地理学的方法,建立-个多元线性回归方程的数字模型对该地区沙漠化过程的发展进行预测。

Abstract: The process in deserti fication, which is caused by the misuse of water resources in upper and middle reaches of river and creats shortage of water supplies and degradation of ecological environment in the lower reaches, has been developing rapidly in the past more than ten years in the lower reaches of Tarim River. In the study, the author selects the Argan Region which is typical cases(in the lower reaches of Tarim River) and gathers some materials by means of fieldwork and according to the aerophoto of different period analysis, especially in accordance with the changes of surface morphologies and their distribute of developments, he tries to illustrate the process in desertification to the Argan Region. Meanwhile, he utilizs a method of geographical analysis tc establish a multiregret problem program which is applied to forecast the developmental trend of process in desertification in Argan region, Xinjiang.
