Abstract


The remote sensing technology is an emerging discipline, which focused on the latest scientific achievements in space, electronics, optics, computer, biology and earth science, and is an important part of modern high-tech fields. A major trend in the development of remote sensing technology, sensor spatial resolution and spectral resolution of a substantial increase in the whole show over five trends that is multi-platform, multi-sensor, multi-temporal and multi-spectral, multi-angle, multi-source remote sensing data is processed quickly and analysis, it has become an indispensable tool for many interdisciplinary research and means. Landscape ecology the research landscape ecosystem structure, function and variation as the basic starting point, and a research discipline of evaluation, planning and management applications based on human interaction with the surface landscape. In recent years, the application of remote sensing technology in landscape ecology is being gradually deepened. Remote sensing techniques in landscape ecology research division of landscape types. Play an important role in the remote sensing data covering a wide range of fast updated features in the landscape pattern study, but the advantages and potential of the combination between far not been fully exploited, mainly as follows: related less applied research, and the use of low-resolution satellite image data. The study in Zhejiang Province Land Surveying and Planning Institute Pingyang land use planning project support, some methodological issues to be solved in order to facilitate the application. Select Zhejiang Province Pingyang region as a study area, the region in December 2002, SPOT-5 panchromatic and multispectral image as the main data and panchromatic images has been geometric correction, consistent with the topographic maps than better. Starting from the the landscape classification actual demand, as a platform to ERDASIMAGINE remote sensing image processing system, SPOT-5 panchromatic and multispectral images match; the IHS transformation method, Brovey transform and PCA ways Panchromatic and multi- spectral image fusion and fusion algorithm of objective and subjective evaluation method, to obtain the following results: 1. ERDAS IMAGINE functionality development, expansion; 2. system depth understanding of remote sensing image fusion technology , and SPOT-5 images in-depth study of the three basic image fusion method, proposed based on the integration of landscape classification algorithm evaluation; given set of methods for the use of remote sensing images in the ERDAS IMAGINE platform landscape classification ; 4.SPOT-5 remote sensing images can be better applied to the landscape classification to meet the county level landscape classification requirements, after the integration of image processing such as extraction landscape features.
