Human survival and development must rely on various resources, and eco-environmentis inevitably contaminated by the discharge of wastes from human production and livingactivities. For the limited capacity of resource supply and environment’s capacity to waste andpollution, we must ensure the human activities within the capacity of resource supply andenvironmental endurance, i.e., within the resource carrying capacity (abbreviated as “RCCâ€)and environmental carrying capacity (abbreviated as “ECC1â€).With RCC and ECC1in thescope of ecological carrying (abbreviated as “ECC2â€) in nature, sustainable development mustbe built on the basis of ECC2.Wuan’s rapid development is accompanied by the heavy drain on resources and seriousenvironmental destruction. The imbalances between the supply and demand of resources andserious ecological overloading in some areas have presented themselves. Wuan is a city ofconcentrated population and abundant resources, it is also the regional urban center and newmedium-sized city, which is being focused on foster in Hebei province, so its developmentinto a microcosm of the resources city.In this paper, we backgrounded the natural, social economic station and eco-environmentof Wuan region. Based on the theories of ECC2and sustainable development, the spatiallayout and spatial differentiation in Wuan region was studied by comprehensive classificationas assessment method. We defined new contents of ECC2based on the traditional ECC2theory with ecosystem resilience, anchorage force of resources and environment and pressureof ecosystem. In this paper, the index system on ECC2in Wuan region was constructedaccording to the new definition, and the sustainable development trend of regional ECC2wasevaluated with the comprehensive assessment model. Finally, this paper provided a series ofrational measurement and proposal from population pressure, economic operation,development and utilization of resources, ecological destruction and pollution and so on.On the basis of the theoretical study of traditional ECC2, this paper revealed the meaningof the ECC2and defined new contents to the ECC2of three sub-levels. Determined by theweight of combining the principal component analysis and hierarchical analysis, to avoid subjectivity is too strong or the evaluation factors be exaggerated, which makes it a perfectcombination of subjective and objective; We made regionalization with objective clusteranalysis to ecosystem resilience, anchorage force of resources and environment and pressureof ecosystem, through that the study of partition about ECC2will be more perfect. |
