摘要
天津市是我国水资源缺乏、人均占有淡水资源最少的城市之一,也是我国地面沉降最为严重的地区之一。地面沉降现已成为天津市的主要地质灾害,并在一定程度上制约着天津城镇的可持续发展。天津市平原区洼地众多,这些洼地大部分是天津市的湿地分布区。在洼地内建设应急地下水水源地,既可以起到为城区供水,缓解城区的地面沉降,又可以改善洼地生态环境的作用。
Tianjin,as one of the least per-capita share of freshwater resources in China,is a city with severe water shortage,and is also one of the most serious land subsidence areas in China.Land subsidence in Tianjin has become the major geological hazard and is restricting the sustainable development of Tianjin.There are many depressed areas in Tianjin plain,most of which are wetlands.Building emergency groundwater well fields in depressed areas can supply water for the urban,relieve the land subsidence in urban areas and improve the environment of the depressed areas.
