(1) In the meteorological landscape of northern mountain scenic spots, it can be seen that the number of sunrise days is negatively correlated with the number of rainy days, and the number of sea of clouds is positively correlated with the number of rainy days. From 196 1 to 2005, the number of rainy days in Taishan Scenic Area decreased, which increased the number of observable sunrise days and decreased the number of observable sea of clouds.
(2) The influence of climate change on the natural landscape of northern mountain scenic spots is mainly manifested in two aspects: one is the influence of climate warming on vegetation; The second is the influence of precipitation change on water landscape. According to the observation data of plant phenology, two plants, Robinia pseudoacacia and Platanus acerifolia, were selected to study and analyze their effects on vegetation, and it was found that the "green" color state and scenery of vegetation in the scenic spot were prolonged to some extent. The impact on water landscape is directly related to rainfall and temperature. The water landscape of Mount Tai scenic spot has obvious seasonality, and the number of liquid viewing days of the water landscape in the scenic spot has an increasing trend.
(3) Through the influence of rainfall, precipitation composition, wind speed and lithology on Taishan time, the influence of climate change on the cultural landscape of northern mountain scenic spots is analyzed. It is found that the damage degree of Taishan stone carvings is positively correlated with rainfall, and has the characteristics of interannual variation. The precipitation composition of Mount Tai is acidic, and the stone carvings are more seriously eroded by water. The annual variation of weathering process of Taishan stone carving is relatively balanced; Taishan stone carvings are less affected by rock mass.
(4) The influence of climate change on the tourism of northern mountain scenic spots is mainly reflected in the tourist motivation, the tourist experience in the process of tourist activities and the influence of disastrous weather on the tourism of northern mountain scenic spots. There is no correlation between the number of tourists in each month and year and the number of rainy days, but it is consistent with the monthly average temperature change. The analysis of the influence of climate change on the quality of tourism experience is reflected by the evaluation of tourism comfort. It is found that the tourist comfort of Mount Tai scenic spot is polarized in summer and winter. The month that is "very suitable" for traveling is September, and the month that is "suitable" for traveling is March-10.
(5) The response of northern mountain scenic spots to climate change is mainly reflected in four aspects: overall strategy, tourism landscape, tourism products and disastrous weather.
