崇明岛风景旅游区空气负离子监测评价方案研究

崇明岛作为上海市的未来生态岛屿,至今尚未开展过系统的空气负离子研究。依据该县相关规划,结合区域植被、地貌、人为影响等因素,在东滩国家级自然保护区、东平国家森林公园、前卫村、明珠湖和西沙湿地5个监测区域共选定了18个空气质量监测点进行研究。按崇明风景旅游区的具体情况,对国内外7种空气负离子监测评价方法进行了比较,最终确定选用安培空气质量评价系数、森林空气离子评价系数、空气负离子系数评价法、轻重离子比评价法来对该岛的空气质量进行评价。最后还对相关负离子监测仪器进行了分析及建议。

A Scheme Study on Monitoring and Evaluation of Aeroanion in Chongming Island

As an ecological island to be constructed in Shanghai,there has not yet been any systemic study conducted on aeroanions in Chongming Island till now.To begin with,eighteen monitoring sites were chosen according to the vegetation,physiognomy,human activities in the scenic spots of Chongming Island covering five areas,namely Dongtan National Nature Reserve(3 monitoring sites),Dongping National Forest Park(6 ones),Qianwei Village(3 ones),Mingzhu Lake(2 ones) and Xisha Wetland(4 ones).Secondly,four methods out of seven ones for evaluation of aeroanions were selected based on the characteristics of Chongming scenic areas,i.e.,Ampere air quality evaluation,forest aeroion evaluation,aeroanion evaluation,and heavy-and-light-ion ratio evaluation.Finally,types of the monitoring instrumentation were suggested to monitor negative ions,positive ions,large ions and small ions with high automatic level.
