| 摘 要： | 中国大部分风景区位于山区,泥石流时有活动,破坏景观资源,危害生态环境,危及游人安全,而风景区泥石流往往暴发频次低,多含有漂木。分析了风景区泥石流防治的需求和特点,提出了风景区泥石流防治以保护自然景观和生态环境为主、灾害治理工程与自然景观相协调的基本目标。通过泥石流形成区源头治理、新型结构(梳齿坝、滤水坝、预制组合结构)和林内分散拦淤等措施,实现风景区的泥石流的治理目标,形成了以减灾工程与自然景观相协调和工程减灾与生态减灾功能相结合的风景区泥石流治理技术。采用这些技术对世界自然遗产九寨沟的14条灾害性泥石流进行治理,有效地控制了泥石流的发生和成灾,达到了保护景观资源、生态环境、游客与居民安全的目的。

| Abstract: | Most national parks in China are located in mountain areas and have been suffering from various disasters, especially debris flow. Techniques controlling debris flow in national parks are discussed in details. The basic goal is to protect the landscapes and eco-environrnent and to make engineering works be operated in harmony with landscapes. These techniques consist control work in the source areas and various structures for damming sediment and diverting flows. All works have been put into controlling debris flows in 14 tributaries of Jiuzhaigou, which have set up a model for debris flow prevention in national parks in China. |
