Standardization of regional landscape information for Strategic Environmental Assessment

Several regional landscapes were investigated in different type of ecosystem, in different spatial scale, and gene flow among meta-population in an area. As for ecological studies, natural environments especially river landscapes, country sides, urban areas were selected for intensive study site, these areas were landscape ecologically studied from very wide scale as satellite image to chemical scale as DNA. Then, basing on the information, application of regional landscape information for Strategic Environmental Assessment was discussed among investigators of this project. For example, ecosystem functions were discussed as material flow in natural landscapes, water balance in catchments scale landscape, and fish meta-populations in an area, then conservation strategies of those landscapes were discussed. Especially, we tried to make effort finding out indicators for landscape function. As a result, an indicator of weed communities in countryside, and Ciconia boyciana : high lank species in a regional food web, biological indicators for urban greenery spaces were verified in each model research site. On the other hand, to valuate landscape function for Strategic Environmental Assessment, an extension tool for ArcGIS was developed as EcoGIS (a product from Central Research Institute of Electric Power Industry, 2004). Using the tool, ecotope maps which considered to be applied for Strategic Environmental Assessment were easily established basing on GIS system.
