湿地公园声环境效应

随着旅游业发展，对环境影响日益凸现。笔者以无锡市蠡湖公园为例研究城市公园旅游环境效应。从旅游活动与环境间的关系，旅游建设和环境间的关系，环境对游客的影响3个方面着手，研究旅游环境效应。研究结果表明，游客量（N）与旅游噪声源（Leq，dB）之间的关系是Leq =19.91+7.08191nN。声波在传播过程中因园林植物的吸收、反射等作用损失了4.3dB，蠡湖公园内植物宽度、密度、高度、种类组成以及林带结构方面在噪声削减方面未完全发挥作用。大多数游客对蠡湖公园的声环境表示满意

Study on the Sound Environment of City Wetland Parks

With the development of tourism and recreation, it is obvious that tourism and recreation have paid attention to environment. Environmental problem has become one of the main obstacles to sustainable tourism development. The author researched the tourism environmental impact in the Lihu parks. The paper included influences of tourism activities and recreational building on environment, and influences of environment on tourists. The author found as follows: (1)The relationship was Leq =19.91 7.08191nN between the noise of tourism(Leq, dB) and the number of tourists(N). (2)The vegetations of Lihu parks could purify atmosphere efficiently. The rates of removal NOX, SO2 were 7.7%~11.7%, average 32.3%, 28.1%~37.5%, average9.9%, separately. (3)The most of tourists are satisfied with sound environment.
