摘要
深圳市湿地类型有近海及海岸湿地、河流湿地、湖泊湿地和人工湿地共4大类,总面积12 188.57 hm2,占深圳市国土面积的6.12%。本研究提出深圳市湿地保护和利用模式。湿地保护模式分重点保护湿地和一般保护湿地两个层次,重点加强湿地自然保护区的保护与管理。湿地利用模式划分为防护型湿地、资源利用型湿地、水质净化型湿地和湿地公园。水质净化人工湿地作为一种新型高效生态水质净化技术,可应用于污水处理厂尾水深度处理、河水水质净化、面源污染控制与水源保护等领域。湿地公园是对城市湿地面积缩减的弥补和平衡,具有综合生态服务功能,对城市湿地保护和可持续发展具有重要意义。
There are four main types of wetlands in Shenzhen ： coastal wetlands, river wetlands, lake wetlands and constructed wetlands. Their areas account for 6. 12% of Shenzhen currently. The research put forward wetland protection and utilization model in Shenzhen. Protection modes of wetland are divided into two levels ： key protection wetland and general protection wetland. Wet- land nature reserve as the key protection wetland should be strengthened, protected and managed. Utilization modes of wetlands are divided into safety protection, resource utilization, constructed wetland for water purification and wetland park. Constructed wetland as a new type of high efficient ecological water purification technology can be used in advanced treatment of tailwater from municipal wastewater treatment plants, purification of polluted river, non -point source pollution control and water source protec- tion. Wetland parks can compensate and balance wetland areas＇ reduction, and have comprehensive ecological service functions, with significance to urban wetland protection and sustainable development.
