Research on Ecological Function Regionalization Based on the Ecological Service Function - Take Shenzhen River and Xinzhou River Estuarine Wetland for Example

Abstract

The fundamental principles and methods of ecological function regionalization were defined in this paper based on field investigation in the estuarine wetland of Shenzhen River and Xinzhou River. The regionalization scope of the two rivers estuary wetland was delineated, and the main ecological service functions, such as climate regulation, water purification, material production, biodiversity conservation, wildlife habitats, education, recreation and tourism etc., were analyzed and summarized in accordance with the integrity of the eco-system and the administrative divisions status quo. According to the proposed regionalization principles and methods, the two rivers estuary wetland was divided into 6 ecological function units combined with its service functions and distribution characteristics, which were urban construction control area, terrestrial forest ecological belt, futian national mangrove reserves, mangrove restoration area, off-shore tidal flat reservation and estuary waters comprehensive treatment area. For each ecological function units, the leading service functions, Status quo and existing problems were elaborated, the ecological protection, repairation and restoration directions were pointed out, and the strengthening measures of ecological service function were put forward.
