岗南,黄壁庄水库降水效应的分析

修建水库后水域面积的扩大必然会引起一些气候要素的变化。本文根据岗南、黄壁庄水库地区建库前后多年的降水量统计资料,采用回归分析法和综合系数法,比较科学地分析了大型水库水体对其周围地区降水量的影响效应。结果表明,建库使得该地区降水量的时空分布发生了变化。

ANLYSIS OF THE PRECIPITATION EFFECT OF GANGNAN AND HUANGBIZHUANG RESERVOIRS

Expanding of water area after reservoir construction will certainly bring about changes of some climatic elements. On the basis of statistical data of precipitation before and after the construction of Gangnan and Huangbizhuang reservoirs, the effect of large reservoirs on the precipitation around this area was analyzed by regression analysis and comprehensive coefficient method in this paper. The result shows that the chronological and spatial distribution of precipitation in this area are changed caused by the existence of these two reservoirs.
