| 摘 要： | 本文以联合国粮农组织推荐的改进彭曼-蒙特斯公式为基础,通过日气温计算年蒸发总量并验证,用典型年预测全流域年平均气温增加时,参照蒸散发的变化情况。研究表明:长江流域的年蒸发量将随年平均气温的上升而增加;上游增幅大于中下游,各月增幅相近;气温增幅的年内分布不容忽视,考虑到年内气温不等量增长后的计算结果相对更为合理。研究结果表明:当流域年平均气温升高1℃时,流域上、中下游参照蒸散发分别将增加5%和4%.研究中未考虑气温日较差的变化.

| Abstract: | It is a national policy to use the land rationally and efficiently. To develop and rehabilitate the land resources enthusiastically is very important for our country to release the intense supply and demand contradiction of land, to realize the homeostasis of farmland and to accelerate the sustained development of social economy and the sustained use of land resources. The analysis of supply and demand equilibrium of water resource in the item area is one of the important basic works and its aim is to solve the supply and demand problem of the water re-source and calculate the rebuilding project scale of water resource in the item area and compile a scientific, rational and flexible item plan for land and resources development and rehabilitation according to the local conditions such as natural resources, the use of land and the water resource. |
