以淮河上游为例,基于信阳气象站近58 a日气温资料,采用Mann-Kendall秩次相关检验法分析检验了气温变化趋势及以息县水文站近45 a日流量资料为基础的气候变化背景下的水资源响应与变化趋势。结果表明,淮河上游气温与水资源的趋势有规律性的变化,年均气温升高与大规模人类活动密不可分,气候变暖对区域水资源的影响不明显。 Taking the upper reaches of the Huaihe River as an example, based on the temperature data of Xinyang weather station near the 58th a day, Mann-Kendall rank correlation test was used to test the trend of temperature change and the climatic change background based on the flow data of the Hydrological Station in the past 45 days Water Resources Response and Changing Trends Under. The results show that there is a regular change in the trend of air temperature and water resources in the upper Huaihe River. The annual average temperature is closely related to large-scale human activities, and the impact of climate warming on regional water resources is not obvious.
