3S与模型方法在湿地景观格局研究中的应用述评

湿地景观格局研究是景观生态学和全球变化研究领域中的热点问题。3S技术与模型方法相结合,已成为湿地景观格局研究重要的途径与手段。论文首先介绍了景观格局研究的3S与模型方法的基本进展,在此基础上综述和评价了3S技术与模型方法支持下的湿地景观格局的研究方法及其应用。重点探讨了遥感数据源的选择与分类、基于GIS的湿地基础参数的获取与使用、景观指数模型与动态模型在定量表征和解释湿地景观格局与时空变化方面的应用等几个方面的问题,最后分别就提高遥感分类与制图精度、构建指数模型筛选体系以及增强景观模型特别是动态模型的应用与解释能力等方面提出了建议与研究展望。

Review on application of 3S and modeling methods in wetland landscape pattern researches

The wetland landscape pattern research has been one of the key research fields of landscape ecology and Global Changes. 3S technology and modeling methods have been applied widely and proved to be important approaches in wetland landscape researches, Based on researches of 3S and model methods in wetland landscape pattern, this paper reviews the following research methods such as the RS imagery data selection and classification, the measurement of wetlands' basic data and parameters, the landscape index and dynamic models' application in quantitative analysis of wetland landscape patterns and changes. Several key problems including the increase of classification and cartography precision, application and improvement of dynamic models are also emphasized in this paper.
