摘要
针对我国海岸带典型生境识别和空间分布缺乏定量研究的现状,以温州海岸带为例,提出基于遥感影像、现场调查和资料收集等海岸带典型生境的识别方法,精准识别河口、海岸带防护林、盐沼、砂质岸滩、淤泥质岸滩、基岩岸滩、红树林、特别保护海岛、重要渔业资源产卵场、珍稀濒危物种集中分布区、沙源保护海域的面积、空间位置和边界,统计描述各典型生境在不同区县的现况.根据典型生境的分布特征,制定相应的生态保护与修复的目标和措施.研究结果可为海岸带综合保护与利用规划提供技术支撑.
Abstract
In light of the lack of quantitative research on the identification and spatial distribution of typical habitats in China's coast-al zones,this study takes the Wenzhou coastal zone as an example and proposes a method for identifying typical habitats based on re-mote sensing images,field investigations,and data collection.This method accurately identifies the areas,spatial locations,and boundaries of estuaries,coastal protective forests,salt marshes,sandy beaches,muddy beaches,rocky beaches,mangroves,special protected islands,important fishery spawning grounds,concentrated distribution areas of rare and endangered species,and sand source protection areas.The study also provided a statistical description of the conditions of each typical habitat in different districts and counties.Based on the distribution characteristics of these typical habitats,corresponding ecological conservation and restoration goals and measures are formulated,providing technical support for the comprehensive protection and utilization planning of coastal zones.
