Researches on the Dynamic Changes of Wetland Ecologic Landscape Pattern Based on 3S Techniques

摘要

In this paper, taking Zhalong wetlands reserve, which is the largest habitat of red-crowned crane in China as the research object, based on 3S technologies (Global Positioning System (GPS)), Remote Sensing (RS), and Geographic Information System (GIS)), using the LandsatTM remote sensing images in 2005 and 2008, and a 1 : 50 000 topographic map as basic data resources, by applying theories and method on landscape ecology, it studies the dynamic changes of wetlands ecologic landscape pattern. Moreover, this paper conducted a quantitative and qualitative analysis on the utilization of land, the temporal and spatial evolvement of land coverage, which therefore provide basic data for wetlands protection and the researches on water fowls' inhabitation.
