摘要
为了认识地区水循环规律,保障水安全并改善生态环境,依据1965～2000年97个水文、气象站实测资料,结合自然地理特征,对云南水循环进行了分析。结果表明,云南省水循环主要特性为空间分布差异大和季节变化明显。结合地形地貌、水循环时空分布差异性和人口经济分布等,进一步分析了水安全的主要影响因素。提出了遵循水循环客观规律、保证水安全的若干建议。
In order to understand the regional characteristics of the water cycle, ensure the water safety and improve the ecology and environment, the water cycle characteristics in Yunnan Province are analyzed based on the observation data of 97 hydrological and meteorological stations from 1965 to 2000 and the natural geographical features. It shows that the characteristics of water cycle in Yunnan Province are different in spatial distribution and change with seasons obviously. Considering geomorphology, differences in spatial distribution of the water cycle, population and economics, the main influential factors of water safety are further studied. Some suggestions are proposed by following the objective laws of the water cycle and ensuring water safety.
