(January 2010) Indicators System Design of Beijing Mentougou Eco-City
Beijing Mentougou Eco-City planning site has great value of Ecological Conservation for the downtown of Beijing city, and has high biodiversity in the mountainous ecosystem. However, the economic condition is very poor. There used to have lots of mines including coal mines and stone mines, which have made great contribution to the development of Beijing downtown. Before the opening of 2008 Olympic Games, nearly all the mines have been shut down. The central government of Beijing encourages Mentougou to develop in the ecological friendly way. Therefore, the local government would like to develop low-carbon economy, sustainable lifestyle and ecological culture, and finally realize the goal of Eco-city.
But what are the appropriate Eco-city criteria for this area with the special background? This research will develop the indicators system for Beijing Mentougou Eco-City, which could be used as the criteria in the process of planning, construction and assessment. Indicators must be clearly defined, reproducible, unambiguous, understandable and practical, and will reflect the interests and views of different stakeholders (Hartmut Bossel, 1999).
The structure of the indicators system set will be comprehensive and compact, covering all relevant aspects, including the ecological condition, economic development and social culture. Each of the three parts has sub-indicators, which can be viewed as representing a certain type of potential that is vital to the development of the total Eco-City system. A more systematic approach must look at the interaction of the indicators. The crucial part is identifying the essential relationships in a system. This requires a process of aggregation and condensation of available information, and adopts the inter-disciplinary approach.
Based on the indicator system, the flow of material, energy, information and money can be calculated. Hence, the indicators system could handle the complex Eco-City system and assess what their current state means for the health, or viability, of the system in the long run. The results of this research effort are some kind of models-mental models and some more formal mathematical models. These models are then used to identify indicators providing essential information about the system. Therefore, the function and structure of real Eco-City will be illustrated much clearly throw the developed indicators system.
The Eco-City system, and its component systems, the human societal, the resource and environmental system, are complex dynamic systems. If the dynamic haven't been considered, the indicators system will have fundamental deficiency. Therefore, further research is highly needed to solve this dynamic problem.
