生境空气质量测定与评价指标

该指标系统规定了空气生境指数(Air entironment index,简称AEI)、生境空气质量分级、采样点及取值时间,采样与分析方法及数据统计的有效性规定。空气生境指数(AEI)的测定与评价的十个项目:空气洁净度(CI)、空气新鲜度(T)、植物精气浓度、人均绿地面积、绿地植物覆盖率、硬质覆盖率、水体覆盖率、界外植物覆盖率、移植植物树龄或原生植物树龄、植物种类和植物景观。本手册适用于住区生境空气质量评价。住区生境空气质量分为五级:5A级空气质量住区;4A级空气质量住区;3A级空气质量住区;2A级空气质量住区;1A级空气质量住区。

The porameter system of measuring and evaluating the entironment air-quality

The handbook highlights the rules of validity of the AEI, Entironment Airquality Classification, Sampling pointsand time, Methodology and Statistic. There are 10 items of AEI measuring and evaluation, namely the CI, the T, the vegetationvitality concentration, the greenbelt area per person, the greenbelt vegetation cover rate, the water cover rate, the outervegetation cover rate, the age of transplant or protophyte, the plant category and plant view.This handbook adapts to thecommunity AEI evaluation, via the 5 class of the Entironment Air-quality Classification by 5A, 4A, 3A, 2A, and 1A.
