In 2000, The Yangtze River Delta Urban Agglomeration Of Natural Capital Utilization Time And Space Pattern Research

At present, with the rapid expansion of population and the highly growth of economy, the process of industrialization and urbanization continuously promote human civilization and the city to develop rapidly. At the same time, human society has made great achievements, the relationship between the space of human and natural and material relations also change a lot. The economic behavior of human society had led to the outbreak and deepening of the conflict between the health of ecosystem and human social welfare, and the realization of regional sustainable development is imminent.By combing the literature, most of the research had been focused on the measurement of natural capital, and took the constant of natural capital stock as the basis for judging regional sustainable development. In fact, unless improve the efficiency of investment you can ensure the stability of sustainable capacity, the improvement of natural capital utilization efficiency is the the fundamental way to change a country or region from natural capital consumption-based unsustainable development to the fundamental way of sustainable development.Another way, only the improvement of natural capital utilization efficiency can meet people's demand for higher quality of life continuely .In this context, from the basic theory of economics and ecology, this paper analysis the existing natural capital research problems, and try to establish a natural capital utilization and utilization of sustainable development capacity framework, use the model three-dimensional ecological footprint divides the natural capital into stock capital and flow capital, and further uses the DEA model to evaluate its utilization efficiency and the relationship between the two. On the basis of the analysis of the evolution of natural capital utilization and natural capital utilization, it is found that Shanghai is the best developmental city in the Yangtze River Delta. With the passage of time, its natural capital utilization intensity is gradually decreasing and natural Capital utilization rate also has a downward trend,however, most of the urban capital utilization in southern Jiangsu increased gradually,showing a vigorous development trend. From the spatial pattern, the regional central cities tend to show the trend of low capital efficiency and efficiency in the use of natural capital. The natural capital utilization of the cities adjacent to the central cities is generally affected by the trickle-down effect, the city far from the central and lie in the large economic regional link zone has low quality of urban natural capital, mostly belong to "high-ineffective."In order to clarify the main driving factors influencing this spatial pattern, this paper uses the spatial linear regression model to analyze the results. The results show that the main reason for the decline of natural capital is social and economic factors.The development of the tertiary industry, the increase of green area and the life Sewage, garbage treatment rate is conducive to the improvement of natural capital use.In order to improve the regional sustainable development ability and alleviate pressure of the ecology, the Yangtze River Delta region must strengthen the policy supervision and guide the healthy development of the region and ensure the fairness of the development. The establishment of a resource-saving production system,development of characteristic agriculture, ecological agriculture, adjustment of industrial structure; strengthen the comprehensive investment in natural capital,increase investment in education,improve the construction of social security system and other reasonable recommendations.
