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

The various and competing conflicts between different users and different sectors in the use of marine resources will cause the disorderly development of marine resources, and even destroy the marine ecosystem. Marine functional zoning is an effective tool to solve the conflicts. However, there are some shortcomings in the current understanding on marine functional zoning and its practice. In this paper, a case study on the resource-oriented marine functional zoning of Xiangshan Port is introduced. By the principles of resource-oriented and public participation, Xiangshan Port is divided into seven zones, and the main function of the whole port and seven zones are determined by the environmental economics analysis. A case study of Xiamen is also introduced for how to integrate marine functional zoning into a coastal city conceptual planning. Under the conservation principle, resources-oriented principle and so on, the advantages and disadvantages of natural ecosystem, social ecosystem and economic ecosystem are holistically analyzed, the urban orientation of Xiamen is determined as a regional international tourism city, and the whole city is divided into five function zones according to its leading industry -tourism. Resource-oriented marine functional zoning has a long-term guidance for sustainable use of marine resources and development strategy of a coastal city. And environmental economics analysis is an effective tool for resource-orientation.展开更多

It comes to the following conclusions: as the ecological and environmental problems in the BTH area are mainly the air pollution and so on, we should seek to build a mechanism of environmental management for sustainable development from the different aspects of industrial distribution, energy utilization, institution construction and market participation. We should capitalize on the chance to construct the ecological civilization, promote to change the regional economic growth pattern, improve the quality and effi ciency of development, and fi nally promote the synergetic development of ecological environment in the BTH area.展开更多
