Research On The Impact Of Climate Change On Landscape Of Huanglong

Natural Scenic Spots of Huanglong have a worldwide reputation, which is entitled to the honor of "the world natural heritage" or "the international biosphere reserves" or "Global Green 21" etc, and highly named national geological parks, state-level scenic spots and so on.But after years of development in recent years, Huanglong landscape areas have different degrees of variation, including the significantly decrease of water in partial area, the mildly contaminated water, the lack of downstream water, the drop of lake water level, and even some landscape degradation such as dried co lour pool, shrinking waterfalls, metamorphism and darken of adarce, collapsed rimstone dam, sandy adarce etc, which seriously impact the scenic of Huanglong landscape. In connection with the status of declined landscape in Huanglong, this paper specifically discussed the weight of landscape impact caused by climate change. The discussion based on the current points of view of some scholars about "the impact of climate". This paper also shows how the climate changes affect the" water cycle process, water chemistry field, the deposit and corrosion of adarce" in Huanglong.Through investigation of the site and a great deal of information collection, this paper took a more in-depth research of the water cycle process of Huanglong scenic spot on the basis of previous studies, and analyzed the relationship of climate and dynamic hydrological characteristics.Through the scene monitoring and indoor analysis of the water bodies of Huanglong scenic areas and according to the water quality data over the years in Huanglong scenic spot, this paper gave a more detailed classification of the water chemistry field unit In Huanglong, investigated the dynamic changes characteristics of the water quality, and analyzed the relationship of climate and water chemistry field. The paper analyzed the impact of climate change in Huanglong scenic areas on the calc sinter deposit and corrosion process, and focused on the redistribution of water, alternating wet and dry, long-standing dry or wet, changing of appearance of calc sinter and the internal structure, and degradation of landscape.By the contrast of different degradation characteristics of adjacent areas of Huanglong Valley, under he same climatic conditions, and the comprehensive analysis of landscape factors, it can be concluded that the impact of landscape is the base and common impact, whose weight is 30%; Calc sinter its own hydro-geological conditions of the internal changes play a leading role, whose weight of impact on landscape is 60%, while that of human factors affect only about 10%.This paper shows that Huanglong scenic areas are now at the stage of the corrosion, we should increase the research of the hydrogeological conditions, find the right hydrogeological repair technology, and delay the process of its recession.
