The Spatial-time Changes Of Benchmark Land Price And Driving Force Analysis In Mining City

As a special sort of city, mining cities are important components of Chinese town system. Due to impact of resource extraction and mining economy, the evolution of mining cities' urban development and socio-economic composition have some particularity, of which scale and speed of economic development are inseparable with the cities' properties of mining. What's more, urban land price is one of the key indicators in reflecting the size and development of a city. Benchmark land price is one of the statutory land prices in our government and the basis of our country's land price assessment. As the guide in the country land price system, the benchmark land price provides a positive promotion in the coordination of the national economy and sustainable development process.This paper taking the mining city of Wu'an as an example collects the statistical data of Wu'an on the national economy, urban planning, real estate market and such information. By comparing the results of benchmark land prices of Wu'an(1993, 1997, 2002, 2007), and using MapGIS software to analyze the historical evolution of land quality, spatial variations, revealing the temporal evolution of the land Wu'an pattern; in the quality of the land, revealing Wu'an temporal pattern and evolution of land law in the base of the history of the standard land price changes and analysis of spatial variation; Finally, according to the former research, comprehensively analyzing the driving force of socio-economic factors and policy factors on the land price, and the promotion of benchmark land price on rational land using of the city.The results show that Wu'an benchmark land price is rising as time goes on, decreases in space from the central city to the edge region. By analyzing factors affecting land correlation, the main driving forces are regional economic conditions, urbanization, land scarcity and so on. By all these factors, the reasonable land price can guide the optimal allocation of land resources, optimizing the layout of urban land, improving land use degree, helping alleviating the contradiction between supply and demand of our land to promote the healthy development of the land market.
