Development of simulation and evaluation system for ecology and visual landscape, and its application to optimum model of the amenity environment.

一个生态与视觉景观模拟与评价系统(EL-System)已被开发、测试，并通过计算机网络向生态与风景园林研究人员开放。在该EL系统中，生态和景观的模拟和评价往往是通过计算机图形来实现的，为了进行生态和景观状况的分析，需要提供该地区的数字信息数据。在此基础上，从生态和景观两个角度对区域条件进行了评价，并提出了两种条件的优化方案。我们以东京多摩新城为模型，在那里已经有了一些必要的数据，EL-System工作在一个工作站上，在那里可以进行高速的分析、评估和可视化。该系统已向与UT-Net(东京大学的网络名称)连接的调查人员提供。值得注意的是，结果的可视化有助于不同领域的研究人员之间的理解。因此，该系统已被证明是非常有用的宜人环境规划，特别是在生态和视觉景观之间的平衡问题。另一个EL-系统的应用已经在小川群岛进行了测试。为此目的，收集了全新的信息数据。结果令人满意，证明该系统在实践中也是有用的。

A simulation and evaluation system for ecology and visual landscape (the EL-System) has been developed, tested, and made accessible through computer network to researchers in ecology and landscape architecture. In this EL-system, the simulations and evaluations for ecology and landscape are always made visual with computer graphics.To perform the analysis of ecology and landscape conditions, it is necessary to provide numerical information data of the area. Based on these data, regional conditions are evaluated from ecological point of view as well as from that of landscape, then an optimization of both conditions is suggested. We took Tama new-town (Tokyo) as a model, where some necessary data were already available.The EL-system works on a workstation, where high speed analyzing, evaluating, and visualization are made possible. This system has been made available to investigators connected with UT-net (the network name of the University of Tokyo). It should be noticed that the visualization of the results facilitates understanding among researchers belonging to different fields. So the system has been proved to be very useful in planning of amenity environment, especially where the balance between ecology and visual landscape is at issue.Another application of EL-system has been tested for Ogasawara islands. For this purpose, completely new information data have been collected. The results are satisfying, proving the system to be useful also in practice.
