摘要
Abstract
The precipitation data of 29 basic rainfall stations in Langfang City from 2001 to 2023 and the water surface evaporation data of Tumenlou in the same period were selected.The trend line method,moving average method and anomaly percentage method were used to analyze the annual precipitation and annual water surface evaporation in Langfang City.The results show that:(1)The annual precipitation in Langfang City is generally on the rise,and the precipitation varies greatly.(2)The annual water surface evaporation in Langfang City generally increased first and then decreased,and then increased and then decreased.The water surface evaporation changed frequently and varied greatly.(3)Analyze the difference between annual water surface evaporation and annual precipitation.The annual water surface evaporation is larger than the annual precipitation as a whole,indicating that the precipitation in Langfang City is generally less,and the water surface evaporation is greatly affected by topographic conditions and climate.The climate in Langfang City from 2001 to 2023 was relatively dry.The research results have certain reference significance for the prevention of flood and drought disasters and the efficient utilization of water resources in Langfang City.关键词
