摘要
以我国华山、泰山、峨眉山、黄山、庐山、九仙山山岳景区为研究区域,分析了其1970—2018年的年平均气温、年降水量的变化特征,并探讨气候变化对其雨、雪、雾日数的影响,结果表明:(1)1970年以来,这些山岳景区的年平均气温均呈显著上升,年降水量在泰山、黄山、庐山、九仙山增加,在华山、峨眉山减少,可见前四者为增暖增湿型,后二者为增暖变干型。(2)气温增暖已造成山岳景区的年雪日数、年雨日数显著减少,但对年雾日数的影响则存在差异,其中九仙山、庐山呈不显著减少,峨眉山、黄山、华山呈不显著增加,泰山表现为显著增加。(3)年降水量与年雾日数呈正相关,其中庐山、九仙山的较显著;与年雪日数的关系在华山、峨眉山呈不显著正相关,在泰山、黄山、庐山、九仙山则呈不显著负相关;与年雨日数的关系在华山、泰山呈显著正相关,在九仙山、峨眉山、庐山、黄山呈不显著正相关。最后据此提出山岳景区气象景观旅游开发与管理启示。
Taking Huashan Mt.,Taishan Mt.,Emeishan Mt.,Huangshan Mt.,Lushan Mt.and Jiuxianshan Mt.as research areas,this paper analyzes the changing characteristics of annual average temperature and annual precipitation in 1970—2018,and discusses the impact of climate change on the number of days of rain,snow and fog in the mountain scenic spots.The results show that:(1)since 1970,the annual average temperature of the mountain scenic spots has increased significantly.The annual precipitation increased in Taishan Mt.,Huangshan Mt.,Lushan Mt.and Jiuxianshan Mt.,and decreased in Huashan Mt.and Emeishan Mt.,It can be seen that the first four are warming and humidifying,and the last two are warming and drying.(2)In the last 50 years,climate warming has caused a significant decrease in the annual snow days and annual rain days in these mountain scenic areas,However,its effect on annual fog days is different in the mountains,among which Jiuxian Mt.and Lushan Mt.show no significant decrease,Emei Mt.,Huangshan Mt.and Huashan Mt.show no significant increase,and Taishan Mt.show a significant increase.(3)Annual precipitation is positively correlated with annual fog days,especially in Lushan Mt.and Jiuxian Mt.;it is not significantly positively correlated with annual snow days in Huashan Mt.and Emei Mt.,but not significantly negatively in Taishan Mt.,Huangshan Mt.,Lushan Mt.and Jiuxian Mt.;it is significantly positively correlated with annual rain days in Huashan Mt.and Taishan Mt.,but not significantly positively correlated with annual snow days in the other mountains.It also puts forward the enlightenment of tourism development and management of meteorological landscape in mountain scenic area.
