Standardization of regional landscape information for Strategic Environmental Assessment

在不同生态系统类型、不同空间尺度下，对区域景观进行了研究，并对区域集合种群间的基因流进行了分析。在生态学研究方面，选择自然环境特别是河流景观、乡村、城市地区作为集中研究点，从卫星图像的大尺度到DNA的化学尺度对这些地区进行景观生态学研究。在此基础上，探讨了区域景观信息在战略环境评价中的应用。从自然景观的物质流、流域尺度景观的水量平衡、区域内鱼类集合种群等方面讨论了生态系统功能，并对这些景观的保护策略进行了探讨。特别是，我们试图努力寻找景观功能的指标。因此，在农村杂草群落的指标，和Ciconia boyciana：在区域食物网中的高lank物种，城市绿地的生物指标进行了验证，在每个模型的研究地点。另一方面，为了评价战略环境评价的景观功能，开发了ArcGIS的扩展工具EcoGIS（中央电力工业研究院的产品，2004）。利用该工具，可以方便地建立基于GIS系统的可用于战略环境评价的生态环境图。

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.
