This paper is mainly focused on this problem, demonstrating the feasibility and efficiency of environmental study by integrating GIS and environmetal zoning method. Two neighbourhoods of the old city of Wenzhou were chosen as the study area. With the aid of GIS software PC Arc/info as dBate IV, an urhan environmental impact assessment study was carried out based on the data available such as land use map and detailed attribute data of each land planning unit. The main factors taken into consideration include: the type of activity causing environmental stress, the type and strength of environmental impact and the type of receptive area that could be affected.展开更多

However, along with the dramatically economic growth, there constantly emerges environmental and social constraints which may be great challenges of China＇s future sustainable development. In order to optimize the developmental mode, the latest national plan, ＂The 12th National Economic and Social Development Plan （2011-2015）＂, is establishing the ＂Main Function Zoning Strategy＂, which could be considered as a new prototype of national spatial plan and may cover all Chinese territories. Based on the latest ＂Main Function Zoning Strategy＂ stipulated in ＂The 12th National Economic and Social Development Plan （2011-2015）＂, the article builds main interlinks between the spatial development strategy and urban regulatory planning. Secondly, regulation factors in Chinese regulatory planning, which may implement the task of main function zoning, have been clarified and categorized. For each regulation factor, its regulation capability is defined by applying a coding method developed by the author. Finally, according to the output of the study, the spatial regulation approaches to implementing the ＂Main Function Zoning Strategy＂ in Chinese regulatory planning are analyzed.展开更多

Hiroshima City had prospered as a castle town, but severely suffered from A bomb damage at the end of World War II. Since then, Hiroshima City performed greenery activities with restoration and planted trees in public facilities. At present, Hiroshima City is promoting a 3rd tree planting campaign. As part of this campaign, the master plan of greenery of Hiroshima City is being laid. This plan aims not only at beautification in city area but also at ecosystem and biodiversity conservation in expanded city areas. In this paper, we report on the development of the situation in Hiroshima City since the end of World War II and the conservation planning of greenery which, for the most part, concerns zoning.展开更多
