南水北调中线工程调水前汉江水文特性及变化OA北大核心
Characteristics and change trend of hydrological features of Hanjiang River Basin before water diversion of Middle Route of South-to-North Water Diversion Project
基于汉江干流的4个水文站及18个国家气象站的长序列观测资料,采用数理统计、Mann-Kendall检验和Spearman秩次检验法,对南水北调中线工程调水前汉江流域水文特性及变化趋势进行了分析. 研究结果表明:汉江流域大部分地区的降雨无明显变化趋势;气温有显著升高趋势. 4个水文站1999~2013年年径流量多年平均值较1956~1998 年序列均有了不同程度的减小,但总体上无趋势性减小和增加规律. 1956 ~2013年间汉江流域径流经历了多次…查看全部>>
To evaluate the characteristics and change trend of hydrological features of the middle lower Hanjiang River before the water diversion of Middle Route of South-to-North Water Diversion Project, the long term data at 4 hydrologic stations and 18 meteorological stations on the mainstream were selected and the mathematical statistics, Mann-Kendall test and Spearman test were used. The results show that the rainfall in most regions of the basin has no noticeabl…查看全部>>
