山地旅游区域水体观光影响性降雨探讨

A survey of rainfall impact on water tourism in mountain tourism area

流域降雨引起水土流失,影响观光河道水体质量,探讨水体观光影响性降雨特性,对于旅游地水土保持建设和景观资源有效利用具有一定的现实意义。本文以浙江省天台山风景区石梁景区为研究区,通过野外观测,获取流域降雨特性与观光水体浊度数据,借助水体视觉美感和侵蚀性降雨分析,探讨观光影响性降雨的临界值、降雨特性、时空差异及其水色变化规律,得到研究区观光影响性降雨的临界降雨强度为10mm/h,临界降雨量为15mm;指出观光影响性降雨要素临界值界定与流域的地貌、植被、土壤等特性有关。本文提出流域水体观光影响性降雨的概念,提供了确定观光影响性降雨临界值参考方法。

Soil erosion caused by rainfall can affect water quality of the tourism river. This paper explores the regularity of effect of soil erosion on sightseeing water, which has certain practical significance of high quality display of tourism landscape resources. A survey is done on how rainfall affects water landscape quality in Shiliang scenic spot in Tiantai County of Zhejiang Province of East China. Through the field investigation, rainfall and tourism water turbidity data are obtained, and the relationship between rainfall and river water turbidity is established. After exploring the critical value of rainfall impact on tourism, rainfall characteristics, temporal difference and regularity of color changes, this paper points out that the threshold definition of characteristics of rainfall impact on tourism is related to the landforms, vegetation, soil and other relevant properties in the basin. Results show that the critical rainfall intensity of rainfall impact on tourism is 10 mm/h, and the critical precipitation is 15 mm in Shiliang scenic spot. This paper proposes the concept of rainfall impact on tourism in the water landscape, and provides the reference method of determining the threshold of rainfall impact on tourism.
