摘要
人工替代栖息地是一种用于滨海河口区重建丧失的滩涂等栖息地的替代方法。按照长江口自然栖息地的分布特点以及不同栖息地的服务功能,基于人工替代栖息的生态修复和保护可以分为"两圈两带"。"两圈"是指崇明-长兴-横沙"三岛联动"保护圈,以及九段沙新生栖息地为核心的保护圈;"两带"分为城市生态安全带和城市生态调控带。长江口栖息地保护建设规划涉及具有特殊科学研究价值的栖息地和水源地、退化栖息地的生态修复和重建、景观水系整治等多个环节的建设内容,它们与人工替代栖息地的构建相辅相成。
Artificial alternative habitat is a type of habitat reconstruction or habitat alternative method for dealing with habitat loss in coastal estuary such as the loss of tidal flats. According to the geographical distribution and service functions of typical wetland habitats in the Yangtze estuary, we divided wetland of Yangtze estuary into two types based on the theories of ecological conservation and artificial alternative reconstruction. The classification were termed as ＂two circles, two strips ＂. One circle of the＂Two circles＂is the circle which enclose Chongming—Changxing—Hengsha three islands,the other circle is the protected circle whose core is the newly growing wetland Jiuduansha island; ＂two strips＂include city ecological safety strip and city ecological modulative strip. The habitat protection and construction planning in Yangtze estuary involve the measures of reconstructing habitats and water sources with special scientific value,restoring and reconstructing of degraded habitats,improving landscape water system,etc. These multiple measures and the construction of artificial alternative habitat are complement to each other.
