| 摘 要： | 运用Mann-Kendall、Spearman秩次相关检验法、小波分析、持续性分析及多种统计学方法对半世纪来济宁市降雨序列、年平均气温序列及泗河年径流序列的变化趋势、周期及相关性进行了分析。结果表明,济宁市在气温升高的趋势下,年降雨量没有变化趋势而泗河年实测径流量序列呈显著减小趋势;年平均气温和年降雨分别存在18年和9年左右的变化主周期;年平均气温、年平均径流序列的持续性较好而年降雨量序列的持续性较差,且济宁市的气温变化特点与华北地区的气温变化特点相同;年降雨与径流有着较好的同步性,人类的水事活动及土地利用形式的变化对径流造成影响;年降雨量受年平均气温的影响,其变化滞后于气温变化约15年左右。 |
| 关 键 词： | 年平均气温 年降雨 年平均实测径流 演变规律 济宁市 泗河 |
