Establishment of environmental evaluation system using regional environment database

本研究的目的是利用区域环境相关网格型数据库（称为区域环境数据库）建立合理的环境规划评价体系。在1992财政年度，区域环境数据库储存在大东京、东京都和足市。这些数据包括现成的数据库，如国家数字数据存储和零售数字数据存储大东京与额外的原始数据集。为促进数据库的使用，开发了数据库管理系统。在此基础上，对大东京地区地价与环境质量关系、东京都城市环境改善效果评价、宿市住宅开发保护指南等进行了数据库整理。此外，通过对已有模型的改进和对居民的问卷调查开发新模型，建立了对物理、生物和宜人环境进行评价的广义评价模型。在1993财政年度，将1992年开发的系统应用于区域环境规划。在讨论了如何将上述三方面的环境评价综合起来的基础上，提出了用雷达图描述综合结果的方法。在1992年建立的评价模型的基础上，提出了对未来环境的预测和评价方法，预测了环境恶化的进程，并提出了防止环境恶化的对策。使用情景写作法对策略选择的有效性进行了评估。最后，在本研究结果的基础上，结合前人的研究成果，将报告编辑出版为《环境资源与信息系统》一书。

The purpose of this study is to develop the evaluation system for establishing rational environmental planning using regional environment-related grid-type database (called regional environment database).In the fiscal year 1992, regional environment database were stored in Greater Tokyo, Tokyo Metropolis and the City of Zushi. These data include ready-made database such as national numeric datastore and retailed numeric datastore for Greater Tokyo with additional original dataset. Database management system was developed for promoting database usage. As a result, database arrangement was performed for analyzing such as relationship between land price and environment quality in Greater tokyo, evaluation of the effect of improving urban environment in Tokyo Metropolis, and conservation guideline for residential development in the City of Zushi.In addition, generalized evaluation model for assessing the physical, biological and amenity environment was established by improving ready-made model and developing new model through questionnaire survey to the residents.In the fiscal year 1993, application of system developed in, 1992 to regional environment al planning. As a result of the discussion how to integrate the above-mentioned three aspects of environmental assessment, rader-chart was applied for describing integrated results. Further, method for forecasting and evaluating future environment was developed based on the evaluation model developed in 1992, which forecasts the progress of environmental deterioration and propose the countermeasures to prevent, such deterioration. The estimation of effectiveness of policy option using scenario writing method was also successful.Finally, based on the results obtained in this study and the results already obtained in the previous studies, report was edited and published as a book entitled "Environmental Resources and Information System".
