国内外棕地治理技术浅析

Research on Brown Field Management Technology at Home and Abroad

摘要: 随着城市化进程不断加快，工业化迅猛发展，大量污染物如重金属及有机污染物等进入到城市土壤中，通过扬尘和食物链传递等方式威胁着人类健康。土壤不仅是各种污染物的归宿，也是污染物向大气、水体和动植物传播的媒介。土地资源枯竭、城市经济结构调整及生态环境问题的凸现，使得棕地管理与治理愈加重要。本研究通过查阅大量文献，对国内外棕地治理技术进行综述，为我国棕地治理提供借鉴。

Abstract: As the urbanization process continues to accelerate and industrialization develops rapidly, a large number of pollutants such as heavy metals and organic pollutants enter the urban soil, threatening human health through dust and food chain transmission. Soil is not only the destination of various pollutants, but also the medium through which pollutants spread to the atmosphere, water bodies, animals and plants. The exhaustion of land resources, the adjustment of urban economic structure and the emergence of ecological and environmental problems made brown field management and governance more important. This study reviewed lots of domestic and international brown field management technologies to provide a reference for our country’s brown field management.
