China is in a process of rapid urbanization. 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

For the assessment and management of regional to local air quality, an integrated environmental management information system was built within the multi national Eureka project 3266 Webair, http://www.ess.co.at/WEBAIR. The system combines data bases and GIS and a range of coupled models and analytical tools that address a range of typical management problems and cover several levels of nesting from regional to city level and street canyons. The main functions are to support regulatory tasks, compliance monitoring, operational forecasting and reporting, impact assessment EIA (environmental impact assessment), SEA (strategic environmental assessment) and public information within one consistent framework. A major objective is the improvement of air quality through emission control. The integrated model system together with its shared data bases provides a reliable, consistent basis for the non-linear techno-economic and multi-criteria optimization of emission control strategies (including greenhouse gases and energy efficiency). A real-time expert system drives, supports and monitors the autonomous and interactive operations, and provides embedded QA/QC (quality assurance/quality control) functions for reliable operations and ease of use. 展开更多
