红水河-黔江-浔江流域气候分析

本文采用流域内气象站资料,以正交函数展开方法,分析了流域气候背景场的基本结构及共季节变化特征,并根据1985-1988年间在流域内若干河段的小气候考察资料,探讨河流对局地小气候要素的影响。本文给出的河陆风环流平衡气球探测结果,表明了河陆风环流结构的某些特征。

ANALYSIS ON THE LOCAL CLIMATIC CHARACTERISTICS OF THE HONGSHUIHE-QIANJIANG-XUNJIANG RIVER BASINS

Hongshuihe-Qianjiang-Xunjiang river traverses the middle part of Guangxi Basin The river basins have rich hydroelectric resources and mineral resources.Based on the climatic data during the period of 1951-1930 in the river basins at 33 stations and the microclimatic observations from 1985-1987 at the relative river segments,the main climate conditions and the microclimate produced by the river are analysed in detail.The results in this paper provide a scientific basis for exploiting and utilizing the resources in the river basins.Two processes through which the effects of river on local climate are formed,one produced by advective transport and the other caused by the river-land thermal circulation,are presented in.this paper,to expound the mechanism of the river effects on local climate.
