摘要
简要介绍了长江流域水资源二级分区、水资源量等情况。利用1998～2002年长江流域水资源公报汇总资料，着重分析研究了长江流域及其流域各二级区的用水组成情况，农业用水量、工业用水量和生活用水量在总用水量中所占比重，研究了用水量年际间和各二级区间的变化特点和规律。分析计算了长江流域人均综合用水量、万元GDP用水量、农田灌溉平均用水量和人均生活用水量等用水指标，分析了二级区间用水指标的变化情况。通过分析研究，提高了对长江流域用水情况的认识。
The two-grade district division of water resources and the water resource volume in the Yangtze river basin are briefly presented.Water resources data from Yangtze River Basin Water Resources Bulletin of 1998-2002 are used to analyze water consumption situations in the Yangtze river basin and in its second-grade districts;ratios of agricultural,industrial and domestic water consumptions to the total water consumption;characteristics and rules of interannual and interdistrict variations in water consumptions.This paper also analyzes and calculates the comprehensive per-capita water consumption indexes in the river basin,per-10000-yuan-GDP water consumption,unit-area average irrigation water consumption,per-capita domestic water consumption,etc.,and analyzes water consumption indexes' variations for second districts of the river basin.
