摘要
Abstract
By taking the earliestly built Fengman Hydropower Station on the upstream of Songhuajiang River as a case,the statis tics on the data of temperature,precipitation and relative humidity during 1961-2009 from the representative meteorological stations around the reservoir are made,and then the variation trend and features of the climate factors in the recent 50 years after the construction of the reservoir are analyzed,which are compared with the historical recordings within 8 years before the construction of the reservoir,so as to reveal the impact from the construction of large-sized reservoir on the variation of the local climate.The result shows that both the yearly average temperature and the seasonal average temperature present continuous rising trends,while the difference to the annual average temperature from Jilin Meteorological Station shows an obvious rising trend as well.The annual average precipitation in the area of Fengman Reservoir is reduced a little bit,but the ratio between the precipitations near and far away from the reservoir area gives an obvious rising trend.The operation of Fengman Reservoir possibly impacts the lowest annual average temperature of the local climate,and then increases the precipitation near the reservoir area in a certain extent;from which the annual average humidity is reduced a little bit with a warm-dry trend generally and there is no any obvious changes of the total cloud amount,moreover,there is also no any obvious impacts from the operation of the reservoir on the rime landscape therein.关键词
