摘要
本文利用距平法、5a滑动平均法、Mann-Kendall检验法、相关性分析法对浑河上游北口前站、营盘站的蒸发皿蒸发量和日气温、日降水量、日平均风速、日照时数的变化趋势及影响程度进行分析。结果表明:浑河上游存在"蒸发悖论"现象,且10月、11月更为明显;造成浑河上游"蒸发悖论"现象的主要原因是日平均风速的减小。该分析可为辽宁省大部分地区水资源的开发利用、评价和规划提供科学依据。
In the paper, Departure method, 5-Year Moving Average method, Mann-Kendall test method, and correlation analysis method are used for analyzing the variation trend and influence degree of evaporator evaporation amount, daily air temperature, daily precipitation, daily average wind speed and sunshine hours at Hunhe River Beikouqian Station and Yingpan Station. Results show that ‘evaporation paradox’ phenomenon exists in the upper reaches of Hunhe River, and it is more obvious in October and November. The main cause of evaporation paradox in the upper area of Hunhe River is decrease of average wind speed. The analysis can provide scientific basis for development, utilization, evaluation and planning of water resources in most area of Liaoning Province.
