Abstract:

This paper proposed the method of ecological environmental remote sensing complex series mapping based on GPS, RS, GIS, and field integrated investigation and remote sensing images comprehensive interpretation. According to different types of ecological environment in mapping area and different characteristics of Landsat image and its tone, field integrated investigation was conducted to analyse the characteristics of ecological environment types and geomorphology, vegetation, soil and land use of the observation point and its surrounding areas, to interpret the satellite image tones and characteristics, and to find out the direct and indirect marks of interpretation. The first step of mapping is composition of the boundaries of ecological environmental unit in the seeable area, and record the ecological environmental types and coding of various elements. After field integrated investigation, based on reorganization and comprehension of the mapping area, the satellite image interpretative marks were controlled and established. The geographic methods of interpolation and extension were adopted to interpret satellite image. Finally, the ecological environmental unit boundary map was compiled for the whole mapping area. The second step concerning GIS process date and derivation with the aid of computer will automatically compose thematic map of various elements of geomorphology, vegetation, soil, land use and ecological environmental types. This method can not only improve the quality of complex series maps, but can also quicken the map making procedure, which is also convenience for comprehensive analysis and evaluation, especially for setting up unit and data base of geographic information system and ecological environmental information system.
