湿地数据库建立及应用研究

Construction and Application of Wetland Database

湿地是喜水生物及过湿环境构成的特殊自然综合体。湿地数据库是数字化的湿地信息,包括中国湿地数据集与中国典型湿地数据集,它的建设需要探索并构建湿地遥感认知、分类、量化与信息提取的理论与方法,即湿地遥感空间数据挖掘技术;湿地数据库不仅推动了湿地科研的定量化研究,同时也可直接服务于湿地的保护管理与科学决策。本丈就湿地数据库中湿地遥感信息提取方法、湿地格局认知、湿地信息系统与湿地信息共享方面进行了阐述。

Wetlands are a special natural syntheses composed of hydrophilous biology and wet environment.Wetland database is digitized information about wetlands,including Wetland Datasets of China and Chinese Typical wetland Datasets.In the process of wetland database's establishment,theories and techniques about wetland recognition,classification,quantification and information extraction through remote sensing,i.e.wetland spatial data mining,should be investigated and explored.Not only does wetland database promote the further quantitative study of wetland sciences,but can it be served for the wetland protection management and related scientific decision-making.This paper briefly describes wetland database in different aspects including wetland remote sensing information extraction,wetland landscape pattern recognition,wetland information system and wetland information sharing.
