项目摘要

This research conducted six subjects :1) Verification of efficiency of GIS in hydro-environmental analysis (Takara and Hirata). Using an advanced GIS,Takara investigated the effect of spatial resolution of remote sensing images on land cover classification. Hirata varified the effectiveness of GIS in forest environment analysis.2) Development of a fuzzy pattern classification technique and its application to hydro-environmental analysis (Shimizu). Shimizu compared applicabilities of neural network and GMDH to fuzzy classification of remote sensing images.3) Application of GIS to forest environmental analysis (Y.Fukushima and Honda). Using GIS and renote sensing, Honda investigated the influence of deforestation and sabo works in the Ashio copper mine. Fukushima developed a personal computer system for delineating river channel networks based on 50-m DEM.4) Development of image processing system (Fujita). Fujita constructed an image processing system for surface flow velocity distribution using aerial photographs and video images.5) Development of runoff analysis medels (Kojiri, Loo, Tachikawa, and Takara). Loo developed an algorithm for producing DEMs and a distributed runoff model based on DEMs. Tachikawa introduced triangular iregular network (TIN) for precise description of river basin. Kojiri and Takara constructed a runoff model for the Yata River basin based on Detailed Digital Lund Use Data.6) Application of GIS to basin managemant (T.Fukushima and Hori). Hori developed a data base system for geographic, hydrologic, and meteorologic data in the Yodo River basin. Fukushima constructed a system for long-term prediction of water environment in Tokyo metropolitan area.

本研究进行了六个主题：1)验证GIS在水文环境分析中的效率（Takara和Hirata）。利用先进的地理信息系统，Takara研究了遥感图像空间分辨率对土地覆盖分类的影响。Hirata对GIS在森林环境分析中的有效性进行了验证。2)模糊模式分类技术的发展及其在水环境分析中的应用（Shimizu）。Shimizu比较了神经网络和GMDH在遥感图像模糊分类中的适用性。3) GIS在森林环境分析中的应用（Y.Fukushima and Honda）。本田利用地理信息系统和遥感技术，调查了石尾铜矿森林砍伐和毁林作业的影响。福岛开发了一个基于50米dem的个人计算机系统，用于划定河道网络。4)图像处理系统的开发（藤田）。Fujita利用航拍照片和视频图像构建了地表流速分布的图像处理系统。5)径流分析模型的发展（Kojiri, Loo, Tachikawa, Takara）。Loo开发了一种生成dem的算法和基于dem的分布式径流模型。立川提出了三角不规则网（TIN）来精确描述流域。Kojiri和Takara基于Detailed Digital Lund Use data构建了Yata河流域的径流模型。6)GIS在流域管理中的应用（T.Fukushima and Hori）。Hori开发了一个数据库系统，用于收集Yodo河流域的地理、水文和气象数据。福岛建设了东京都市圈水环境长期预测系统。
