Abstract

The invention provides an analysis method and an analysis system for the evolution process of wetland landscape. The method comprises the following steps: acquiring wetland landscape remote sensing image data of a study area; interpreting the wetland landscape remote sensing image data to get different types of wetland landscape distribution maps in different periods and under different hydrological characteristics; and making an overlay analysis of the different types of wetland landscape distribution maps in different periods and under different hydrological characteristics, extracting flow information of wetland landscape type change, and drawing a wetland landscape type change transfer map. Through a remote sensing RS image technology, a geographic information system GIS technology and other technologies, the evolution of wetland landscape is analyzed, the spatial and temporal development and evolution laws of wetland landscape are explored, and wetland landscape is visually displayed using a map. The method and the system are conductive to scientifically cognizing the wetland landscape pattern evolution mechanism in the study area and providing a scientific theoretical basis for reasonable planning and utilization of wetland resources.

Description

technical field [0001] The invention relates to the field of remote sensing analysis of wetland landscape, and more specifically, relates to an analysis method and analysis system of wetland landscape evolution process. Background technique [0002] The wetland ecosystem is one of the three major ecosystems in the world. It belongs to the transition zone between water and land, and is known as the "kidney" and "gene pool" of the earth. Wetlands are rich in biodiversity and are one of the living environments for human beings. Wetlands have irreplaceable functions of ecological conservation and application potential of social resources. At the same time, they are also an important guarantee and foundation for the healthy and rapid development of social economy and ecological security. [0003] With the increase of population and the scarcity of resources, human beings have made intensive and irrational use of wetland landscape, which has severely damaged the ecological enviro...
