摘 要:
黄龙景区的景观是一种高寒山区地表岩溶堆积地貌景观,是由钙华堆积而成的,它是数万年的岩溶地质作用的产物。但近年来黄龙钙华出现了干涸、变黑、沙化等现象,严重影响了景观的可观赏性。深入研究该区的钙华演变规律和影响因素,对于采取科学的保护措施,控制人为活动对钙华资源的不利影响将具有重要作用。同时,对于增加该景区社会、经济、环境效益也具有重要意义。全面分析了黄龙钙华形成的地质、水文背景特征和钙华演变的影响因素,发现黄龙钙华景观目前正处于动态平衡与消亡重组阶段。对黄龙钙华的保护提出了针对性建议。[著者文摘]

GU Ji-rong et al （College of Geography and Environment Sciences, Sichuan Normal University, Chengdou, Sichuan 610068）
Abstract:
The travertine landscape in Huanglong scenic spots is sacrificial deposition in alpine and very cold region. Its formation lasts for several ten thousands. However, in recent years, the landscape come to be dried up, blacken, sanded, which have seriously affected the sight＇s admiring value. It is very important to take the protected measures and control human activity to research the rules and influencing factors of travertine, it will be good to society, economy, environment. The inffluencing factors of travertine landscape in Huanglong are analyzed. The results show that the travertine landscape in HuangLong area stays at the stage between the dynamic equilibrium and the disappearance and recombination. The suggestions about development and protection of the landscapes in the Huanglong are put forward.[著者文摘]
