摘要景观生态学作为生态学和环境科学领域的一门综合交叉学科,近年来发展迅速,其为湿地科学研究带来新的思想与方法。遥感技术具有大范围、多时相的动态检测功能,能够获取客观可靠的数据,GIS 技术强大的空间信息处理功能可以精确的对湿地资源进行评价和动态变化分析,结合遥感和GIS技术,从自然和人文角度探寻湿地演变规律,愈来愈多地被运用至湿地研究中。本文基于国内外湿地遥感提取方法与景观格局模型研究,应用目视解译的遥感图像提取方法,选取斑块类型面积、斑块个数、香农度多样性指数、蔓延度指数等景观多样性指数,采用单一类型变化率模型、区域动态度模型和动态转移矩阵,从而对西溪湿地的景观格局演变和时空变化进行探究,为西溪湿地的进一步保护研究提供基础。70073

As a comprehensive cross subject in the field of ecology and environmental science, landscape ecology is booming in recent years, it brought new research thoughts and method in the wetland science research.Remote sensing technology has wide range, long phase of dynamic detection function, can obtain objective and reliable data, while GIS has strong spatial information processing functions, which can be accurately evaluate the wetland resources and the analysis of dynamic change. It is more and more applied to wetland research that based on remote sensing and GIS technology, exploring the wetland evolution law in the perspective of nature and the humanities. In this paper, based on the research of the method to extract wetland remote sensing at home and abroad and the landscape pattern model, applied visual interpretation of remote sensing image extraction method, selected landscape persity index, such as patch type area, patch number, Shannon persity index, contagion index, and so on, Used single type of change rate model, regional dynamic degree model and dynamic transfer matrix, thus explored the landscape pattern and the change of time and space of Xixi wetland, to provide the basis for the further protection of Xixi wetland.
