新疆哈密石城子河流域水文水资源分析

不同地区的自然地理环境塑造了不同特征的河流,同时,河流的活动也在不断改变着与自身有关的自然环境。我国暖温带干旱区除塔里木河流域的水文特征、水资源及其合理利用有较多的研究外,其余中小河流的研究甚少。哈密石城子河的水文特征基本反映了我国暖温带干旱区众多中小河流域的水文特征。利用石城子河流域水文气象站1956-2001年资料,对该流域径流形成、洪水、泥沙、水质等进行分析,以揭示我国暖温带干旱区中小河流域的基本特征,为科学利用该地带中小河流域水资源提供理论依据。

Hydrological Features and Water Resources in the Shichengzi River Basin

The hydrological features are different from different drainage basins due to the different geophysical and environmental conditions,and the hydrological process changes the natural environment in a drainage basin.Many achievements of researching the hydrological features,water resources and their rational utilization in the Tarim River Basin have been achieved.However,the studies about other drainage basin in the warm-temperate arid areas in China are insufficient.The hydrological features in the Shichengzi River Basin in Hami,Xinjiang,can basically reflect that in many mid-and small-sized drainage basins in the warm-temperate arid areas in China.Based on the hydrological and meteorological data observed by the hydrological and meteorological stations in the Shichengzi River Basin,in this paper the runoff formation,flood,silt discharge,stream water quality,etc.in the drainage basin are lucubrated so as to reveal the basic hydrological features in the mid-and small-sized drainage basins in the warm-temperate arid areas in China and provide the theoretical bases for rationally utilize water resources in these drainage basins.The hydrological features in the Shichengzi River Basin can reveal the formation,development and change process of the drainage water circle in the mid-and small-sized drainage basins in the warm-temperate arid areas in China as well as the hydrological importance in the local economic sustainable development.
