摘　　要：探讨变化环境下岩溶区年降水量、年平均气温的分布特征,并结合水文变异诊断系统和非一致性水文频率计算原理,深入探讨年降水量、年平均气温的变化趋势、成因,印证了变化环境对研究要素的影响是存在的;针对研究区域岩溶发育强度,讨论了其对年降水量、年平均气温之间的关联性。研究结果表明:(1)研究区域各站点年降水量呈减少趋势,年平均气温除个别站点呈上升趋势,年降水量与年平均气温呈负相关;(2)研究区域19个站点中年降水量序列发生变异的有9个站点,以弱变异为主;年平均气温序列全部发生变异,以中变异、强变异为主;(3)变异的发生是确定性成分的加入,这种影响可能来自于气候的、也可能是人类活动的;(4)年降水量、年平均气温在不同岩溶发育区域的变化具有一致性。Based on hydrological alteration diagnosis and the inconsistency of hydrological frequency calculation principle,research on distribution of precipitation and temperature in Karst under a changing environment,the trend and key factor are analyzed,and the effects of changing environment are confirmed,the correlation between karst development and precipitation and temperature is discussed.The results show that①the trend of annual precipitation are down in all stations,the trend of annual mean temperature are rising in most stations,and the series of annual precipitation and annual mean temperature is negative correlation.②There are alterations in 9 of the all stations on annual precipitation series,there are alterations all of stations on annual mean temperature series.③Some reasons lead to the alteration of climate or human activities.④The change of annual precipitation and annual mean temptation on different karst development are consistent.
