鄱阳湖湖泊气候及其围垦后的变化
卢兵, 汪泽培
江西省水文局鄱阳湖水文分局, 星子 332800
摘要:
对鄱阳湖地区30多年的气候资料分析比较得出:鄱阳湖围垦后,年平均气温垦区上升0.11℃,湖区上升0.09℃;年平均最高气温垦区上升0.57℃,湖区上升0.07℃;日最高气温 ≥ 35℃的天数垦区年增加10天,湖区年增加4天;年平均最低气温垦区下降0.26℃,湖区上升0.06℃。水汽压和相对湿度,垦区减少0.05hpa和1%,湖区减少0.16hPa和1%。降水量垦区减少95mm,湖区变化不明显,因而,湖区有向干旱陆相盆地气候发展的趋势。

Abstract:
Based upon the climatic data in Poyang Lake area in the last 30 years, the changes of climatic elements, due to large-scale reclamation, have been observed both In reclaimed area and lake district. Detailed analysis and comparisons between them before and after reclamation are given from the fallowing six aspects:(1) the yearly-mean air temperature has ascended 0.11℃ in the reclaimed area and 0.09 UC in the lake district; (2) the maximum air temperature average 0.57℃ higher per year in the reclaimed area, and also 0.07℃ higher in lake district; (3) Concerning the days when the annual temperature exceeds 35℃, an increase of 10 days and 4 days is noted in the reclaimed area and the lake district, respectively; (4) in the reclaimed area, the yearly-mean minimum air temperature decreased 0.28℃ while In the lake district increased 0.06℃; (5) the vapor pressures have dropped by 0.05 hPa in the reclaimed area and 0.16 hPa in the lake district; the relative humidity also drops 1% in both areas; (6) the corresponding yearly-mean precipitation has decreased by 95mm in the reclaimed area> whereas no distinct change was observed in the whole lake district.
