| 摘 要： | 我国西北内陆河流域的干旱生态系统是十分脆弱的,不少流域生态环境主要因干旱缺水而严重恶化。本文在分析塔里木河流域生态环境恶化的基础上,提出内陆河流域生态环境具有溯源恶变的特点,目前下游地区遭受严重危害,中上游地区潜伏危险,必须引起足够的重视,并提出相应的初步防治意见。

| Abstract: | The arid ecological system of northwest inland river watershed inChina is very fragile. Ecological envirconments have become seriouslydeteriorated becauce of aridity and lack of water in many watersheds. This paper, based on analysing deterioration of the ecolpgical environ-ment in the Talimu River watershed, proposes that ecological environmenthas a characteristic of the retrogressive deterioration in inland riverwatershed. Harm is very serious in the lower reaches and danger is latentit the middle and. upper reaches at present. Therefore, We must pay closeattention them. This paper, finally, proposes some prelimnary suggestionson prevention and control. |
