吴山景区旅游环境空气质量的定量评价

Quantitative evaluation on air quality of tourist environment in Wu Hill scenic spot

目的对吴山景区旅游环境的空气质量进行定量评价和分析,为景区发展、游客出游提供参考。方法用KEC-900正负离子测试仪和KEC-R2型高智能记录仪进行测量记录,选择吴山景区不同位置测定空气中的正负离子浓度变化,对测定结果利用Origin 9.0软件进行统计分析。结果将吴山景区多处测定结果进行归类,分为沟底、山顶、入山口以及"滴水观音"4处,其空气质量评价指数(CI)均属A级;而4处的森林空气质量评价指数(FCI)有所不同,沟底(n-=2 098个/cm3)和"滴水观音处"(n-=2 280个/cm3)属于Ⅰ级,而登山入口处(n-=2 172个/cm3)属于Ⅱ级,山顶(n-=1 322个/cm3)位置属于Ⅲ级,根据上述结果,对吴山景区的旅游开发和环境保护提出了建设性的建议。结论吴山景区空气质量清洁度优良,是生态保健游的好去处。注意旅游开发与环境保护的和谐及可持续性发展,把旅游开发所带来的生态环境破坏降到最低。

[Objective]To take the quantitative evaluation and analysis of air quality of tourist environment in Wu Hill scenic spot,offer reference for the development of scenic spot and journey of tourists. [Methods]KEC-900 positive and negative ions tester,and KEC-R2 intelligent recorder were used to measure and record the data. The concentrations of positive and negative ions in air were detected at different sites of Wu Hill scenic spot,and the results were statistically analyzed by Origin 9.0 software.[Results]According to the detection results,the Wu Hill scenic spot was divided into four places,including mountain valley,summit of mountain,mountain pass and Dishuiguanyin. The air quality evaluation indexes（CI）of four places were all identified as A grade. However,the forest air quality evaluation indexes（FCI）were different in four places. The mountain valley（n- =2 098/cm^3）and Dishuiguanyin（n-=2 280/cm^3） belonged to level Ⅰ,mountain pass（n-=2 172/cm^3） belonged to level Ⅱ,and summit of mountain（n-=1 322/cm^3） belonged to level Ⅲ. Based on the results,the constructive suggestions were given for tourism development and environmental protection of Wu Hill scenic spot. [Conclusion] The cleanliness of air quality is fine in Wu Hill scenic spot,and it is a good place for ecological health tourism. It is important to pay attention to the balance of tourism development and environmental protection,as well ad the sustainable development,to minimize the ecological environment destruction caused by tourism development.
