摘要
湿地景观格局及其动态变化研究是湿地生态学和景观生态学研究的热点。该文总结和探讨基于3S技术与模型方法的湿地景观格局及其动态变化研究,包括研究尺度与区域选择、景观数据获取与处理、景观分类体系构建及指数模型与动态模型的选取与应用等;结合湿地景观格局与动态变化的研究内容,评价湿地景观格局的分异特征、变化过程及其驱动机制等,指出当前湿地景观格局与动态变化研究中存在的问题及改进建议。
The research of wetland landscape has been one of the key research fields of landscape ecology and wetland ecology. In this paper, researches of the wetland landscape spatial patterns and their dynamic changes based on 3S technology and model methods are summarized and reviewed. As some basic research methods, several important aspects such as the scale and the region choice, the wetland landscape data and parameter disposal, the wetland landscape classification and index and dynamic models selection and theirs application are discussed. The research content including the characters and processes of dynamic changes and the driving factors of changes in wetland landscape patterns are also discussed and reviewed. Finally, several key problems which include the scale conversion, the increase of classification and cartography precision, the improvement of classification, application of the dynamic models in the research of wetland landscape are pointed out and emphasized as important research fields in the future.
