摘　　要：基于2005年塔里木河流域8个气象台站、4个探空站及4条源流出山口和干流15处控制断面2005年的水文气象监测资料,对塔河"四源一干"2005年气象和径流情势进行分析。结果表明:塔河流域山区及平原区的气温和降水量均较常年高,天然来水量较常年增加21%,干流输水总量为56.88亿m3,输水改善了河道两侧及下游的水生态环境,但其过程中耗水量仍较大。就第7次向塔里木河下游输水对水环境和生态环境的效应进行评价。Based on the observed hydrometeorological data from eight meteorological stations,four sounding stations,outlets of four headstreams,and 15 control sections of the main stream in the Tarim River Basin in 2005,the meteorology and runoff of the four headstreams and a main stream in the Tarim River in 2005 were analyzed.The results show that the temperature and precipitation of mountain and plain areas in the Tarim River Basin were higher than those in a normal year.The natural water inflow was 21 percent higher than that in a normal year.The water conveyance amount of the main stream was 5.688 billion.The effects of the seventh water conveyance to the lower Tarim River on the water ecological environment were evaluated.
