| 摘 要： | 九寨沟风景名胜区是世界级旅游精品,正确认识九寨沟风景名胜区自然和人为的影响因素的发展变化,对景区的保护意义重大。首先,文章从地层岩性、地质构造、地形条件、第四纪冰川作用和地质灾害等方面详细阐述了地质环境条件对九寨沟景观的形成作用。然后,笔者从地下水岩溶通道的发育、钙华景观演化和湖泊泥沙沉积等方面分析了九寨沟地质环境演化趋势,九寨沟的地下水岩溶通道发育和钙华景观演化处于青壮年期,湖泊泥沙沉积缓慢。最后,作者分析了九寨沟景区的降水变化趋势和周期变化、生态环境的改变状态。通过上述分析,得出了九寨沟风景名胜区景观变化处于相对稳定状态的结论,证实了目前的一些景观退化与大自然的变化趋势是一致的,九寨沟核心景区的生命力尚处于青壮年阶段。

| Abstract: | Jiuzhaigou scenic spot is world-famons travel scene.There is very important meaning that we understand correctly trend of development of natural and man-made factor which influence scenery.Firstly,the article expatiates the geological environment force to form sight from some facet,such as lithology,geological structure,terrain,quaternary glacier and geologic disaster.Then,the author analyses the trend of Jiuzhaigou from some sides,such as growth degree of petrosal soluble dypass,travertine evolvement and bedload sediment of lakes.Subsequently,the author analyzes precipitation trend and change period.In addition,the author analyzes effect of the eco-entironment and human activity.At last,the article points out some conclusions: sight of Jiuzhaigou is in relative steady state,nowadays sight change is accordant with natural variety,and core scenic spot of Jiuzhaigou is in young phase. |
