| 摘 要： | 近50年来洞庭湖四口分水比例持续减少,四口河系地区的水资源矛盾日益突出。本文以作物需水分析方法为基础,以堤垸为单位,预测洞庭湖四口河系地区不同规划水平年、不同降水频率、不同发展模式、不同长江干流来水等情景下的水资源需求并进行供需分析。结果表明：洞庭湖四口河系地区现状总需水量24.4亿方,规划水平年需水量有30%到120%的增加,主要是工业需水增加;现状缺水2.27亿方,规划水平年总缺水量4.5～12.7亿m3,主要缺水区域为华容县与藕池河水系,主要缺水月份为春季与秋季。解决水资源短缺的主要途径为增加水资源调蓄能力。

| Abstract: | The inflow from Yangtze River into the Dongting Lake through its four inlets continued declining during the past 50 years,and the water resources deficit is becoming more and more serious in the four inlets regions.The monthly water demand was predicted using crop water demand estimation method for different target years,different precipitation levels,different developing patterns and different discharges of Yangtze River.The total water demand in 2008 was about 2.44 billion m3,and it will be increased by 3... |
