摘要
娘子关泉是我国北方最大的岩溶泉。也是阳泉市的主要水源。选取降雨量、气温、径流量、泉流量4个指标,分别计算各指标5年滑动平均值.并采用最小二乘法拟合趋势线。对序列进行Mann—Kendall检验。结果表明:1951~2000年娘子关泉域面平均雨量、径流量和泉流量均存在显著下降趋势,年均气温存在显著上升趋势。
Niangziguan Spring is the largest karst springs in north China, also the main water source for Yangquan city. Selected 4 indicators : rainfall, air temperature, runoff and spring discharge, the indicators were calculated for five years moving average value, and using the least squares fitting trend line, the sequence was Mann-Kendall test. The results showed that: 1951 -2000 years of Niangziguan Spring Basin areal mean rainfall, runoff and flow rate were significantly decreased, with an average annual temperature of significant rising trend.
