灵山风景区空气质量分析评价

随着灵山风景区旅游业的蓬勃发展,景区空气质量备受关注。根据灵山风景区景点的水平分布及高度落差,选取了11个具有代表性的采样点,从2010年3月至2011年1月进行空气质量连续监测。结果表明:灵山风景区的空气质量整体较好;焚香点的空气质量明显低于其他景点;客流量是影响景区空气质量的主要因素之一。在环境监测的基础上,采用改进的灰色聚类法对景区内各采样点进行空气质量评价,发现除百子戏弥勒、祥符禅寺、大佛3个采样点的空气质量为国家二级,其余采样点的空气质量均达到国家一级标准。辅以SPSS分析,发现空气质量等级与TSP、PM₁₀、PM_2.5浓度之间显著相关,说明颗粒物对空气质量等级的影响较之SO₂、NO₂更大。

The Analysis and Evaluation of Air Quality of Lingshan Scenic Area

Along with the development of tourism,the air quality at Lingshan scenic area has aroused general concerns.According to the plane layout and altitude distribution of the Lingshan scenic spots,eleven representative sampling points were set,and a continuous air quality monitoring programme was carried out from March 2010 till January 2011.Results have shown that the air quality at Lingshan scenic area was fairy good in general whilst fluctuating,however,that at incense burning points of the religious attractions was obviously inferior.The flow of tourists was found to be one of the key factors to influence the air quality of the scenic area.On the basis of environmental monitoring,an improved grey clustering method was used to evaluate the air quality at various sampling points.It has indicated that the air quality at three points,namely the hundred boys playing with Maitreya,Xiangfu Temple,and the Great Buddha,was at Class 2 of the ambient air quality standard,whilst that at the rest places was all in compliance with Class 1.Supplemented by an SPSS analysis,the air quality classification was closely correlated with the levels of TSP,PM₁₀ and PM₂₅.It meant that the particulate matter had more effects on the air quality than SO₂ and NO₂.
