The regularities of water transform in stream forming area and disappearing area are quite different. In stream forming area, water transform is mainly that groundwater flows out to form surface water. And in stream loss area, water transform is mainly that surface water seeps into ground. At the perimountain plain, when the transform of surface water-groundwater- surface water finishes, it may begin the second transform if there is a structural basin in the lower reaches of rivers.

The regularities of water transform in stream forming area and disappearing area are quite different. In stream forming area, water transform is mainly that groundwater flows out to form surface water. And in stream loss area, water transform is mainly that surface water seeps into ground. At the perimountain plain, when the transform of surface water-groundwater- surface water finishes, it may begin the second transform if there is a structural basin in the lower reaches of rivers. However, water becomes less and less after the process of transform. Effect of water to environment can be divided into two types, natural effect and human effect. The changes of natural conditions need a long time of geological period. The influences of human activities take place in a short time and regionally, especially in arid land where water is the key factor of environment. Hydrological changes in Xinjiang are mainly that: part of river courses has been replaced by artificial canal system; some lakes are replaced by reservoirs; and water table has changed. Located at the upper reaches of Tarim River, Afar irrigation area is reclaimed after 1958. With the expansion of irrigation area after land reclaiming, much of water seeped into ground from canals and farmland to feed groundwater. Seasonal change of water table is based on irrigation periods. Mineralization of groundwater has reduced but most of the drained water flows into rivers or lakes, river water quality has changed too. The redistribution of water is mainly that: water quantity has been improved within oases, but runoff in the lower reaches has reduced. Alar irrigation area is the largest new oasis with stable agricultural eec-environment in Tarim Basin since the redistribution of water resources. Hydrological and climatic conditions are improved within the oasis.

新疆的水平衡特征是，徑流形成于山區(qū)，流到平原區(qū)后不斷蒸發(fā)和滲漏，最終消耗在沙漠中，，或者流入尾閭湖。由于人類(lèi)活動(dòng)的影響，水的分布和轉(zhuǎn)化都發(fā)生了改變，綠洲中的水量增加，但綠洲以外與河流下游的水量減少，同時(shí)有些湖泊縮小甚至干涸，沙漠化發(fā)展，自然植被衰退，自然環(huán)境退化。

Most of the groundwater in mountain area is transferred to ground surface as the runoff in Xinjiang.Groundwater at plain area mainly comes from infiltration of river water,lakes,canal system,reservoirs and irrigation.And 78.5% of it is seeped river water.Infiltrating water in agricultural area is caused by human activities,which has changed the water table and groundwater quality to a great extent,and changed the movement process of groundwater. \ \ Alar irrigation area established in 1958 located...

本文分析了新疆地下水的轉(zhuǎn)化規(guī)律，特別是平原區(qū)地下水的補(bǔ)給關(guān)系。對(duì)塔里木盆地阿拉爾地區(qū)開(kāi)墾后的地下水變化特征和人類(lèi)活動(dòng)對(duì)地下水的影響做了重點(diǎn)分析。結(jié)果表明人類(lèi)活動(dòng)改變了水資源的分布狀況，使綠洲內(nèi)部地下水位上升，水質(zhì)改善；但綠洲以外地下水位下降，河流由于接納了綠洲排水，水質(zhì)變差。

So it is important to control the expansion of land reclamation and enhance the efficency of water resources utilization in upper reaches of Tarim River.

Water resources are becoming more and more shortage in Tarim arid region. So it is important to control the expansion of land reclamation and enhance the efficency of water resources utilization in upper reaches of Tarim River. It is also significant for the development of Tarim region to resolve the conflict between agricultural using water and ecological using water. Remote sensing technology is the best way to analyze the dynamics of land use. In this paper, the author discussed the dynamics of land use in typical region-Alaer(K-44-127,1∶100,000) by using the aeronautical maps and satellitic maps which were made in 1959,1983,1992 and 1996. The results showed that in this region the artificial oasis and residential area were enlarged step by step. On the contrary, the area of natural vegetation shrank year by year. As for the other land using types, the area of lakes decreased quickly and the area of usless land types has no great change for these years, e.g. the desert and the salina. Therefor the local goverment should strictly control the enlargement of land reclamation in upriver of Tarim River in order to save the lower reaches of Tarim River. And at the same time, we should strengthen the construction of vegetation to improve the ecological environment.

在干旱區(qū) ,水資源十分匱乏。若能有效的控制塔里木河上游耕地面積的擴(kuò)張 ,同時(shí)提高水資源利用率 ,則能解決塔里木河流域長(zhǎng)期以來(lái)農(nóng)業(yè)用水和生態(tài)用水之間的矛盾 ,這對(duì)塔里木河流域持續(xù)發(fā)展有重要意義。應(yīng)用遙感技術(shù)進(jìn)行上游土地利用動(dòng)態(tài)變化則為上游耕地現(xiàn)狀和趨勢(shì)發(fā)展提供一種快速和準(zhǔn)確的方法。本文利用 1 95 9年、1 983年、1 992年和 1 996年四個(gè)時(shí)期的航片及衛(wèi)片資料 ,研究了塔里木河干流上游典型圖幅土地利用的動(dòng)態(tài)變化。結(jié)果表明 ,研究區(qū)域人工綠洲和居民點(diǎn)面積逐年擴(kuò)大 ,湖泊面積明顯縮小 ,而天然植被面積趨于縮小 ,難利用面積變化不大。為此 ,有關(guān)部門(mén)應(yīng)嚴(yán)格控制目前這種耕地繼續(xù)擴(kuò)張趨勢(shì) ,同時(shí)加強(qiáng)植被生態(tài)環(huán)境建設(shè)
