林木绿化工程改善工业污染区生态环境的研究

通过对广州市员村工业区２０个监测点的大气监测资料及天河区环境监测站１９８９年～１９９４年连续６ａ大气监测资料，运用模糊数学进行环境现状及回顾评价，采用统计方法进行方差分析，并用灰色系统理论建立污染物时空分布模型，找出污染物分布规律，获得员村地区环境现状及发展趋势的基本资料．同时在对员村植被与绿化现状调查研究基础上，依据环境生态及生态园林理论和国家一级大气环境质量标准，组建高效的自然净化系统．

Improvement on Ecological Environment of Industrial Polluted Area by Greening Engineering

The atomosphere monitoring has been carried out at twenty monitoring points in Yuancun industrial district, Guangzhou. The atomosphere monitoring data of Tianhe district six years (from 1989 to 1994) has been gathered from the Environmental Monitoring Station of Tianhe. Based on the observational data and the gathered data,the present and past status of ecological environment of Yuancun district has been assessed by Fuzzy mathematics. And then a time-space distribution model has been made by grey system theory,and a distribution law of pollutants has been found out. On the basis of investigation of Yuancun's vegetation and greening status,a high-efficient natural purifiying system can be founded according to the environmental ecology and ecological landscape theory and the China first-rate atomosphere criteria.
