A Study On The Spatio-temporal Difference Of The Influencing Factors Of The Constuction Land Expansion In Large And Medium-sized Cities In Hubei Province

Urbanization in the central conference pointed out that the urbanization is the only way for towards modernization in our country. As an important support of urbanization, the construction land once again be the focus of attention. Increasing urbanization rate, will inevitably drive the construction land expansion. Many studies have shown that construction land expansion is bound to take up the cultivated land around, leading to loss of high quality cultivated land, thus affecting the national food security. However, our country is a much less, a severe lack of arable land resources, to maintain economic development, must be reasonable and effective use of land, strictly control the blind expansion of construction land. Hubei as the fulcrum of the rise of central China, facing the same problem, under the background of new era, large and medium-sized cities in hubei managers will how to choice, this article will be to do a full analysis the influence factors of construction land expansion, thought beneficial reference for the government to make decision.This article use16large and medium-sized cities in hubei province as an example, each city proper as the research object. Through the urban area with impact factor do spatial econometric analysis, The following conclusions:(1) Thanks to the fast development of economy and society in recent years, the urban construction land expansion fast in hubei province, but has obvious differences between all the cities;(2) from the global point of view,The urban construction land in hubei province showed no significant correlation. But look from the local, the urban construction land in hubei province showed obvious accumulation, mainly to the low-low area.(3) GWR model running results show that although industry ratio, urbanization rate, greenbelt area per capita, per capita road area of urban construction land expansion effect is remarkable. And shows significant difference in time and space. Urbanization rate, the per capita green area is significantly positive influence to each city, road area per capita of each city construction land expansion is a significant negative correlation. And although three two industry ratio have significant volatility in different cities and years, it may show the positive correlation, may also show the negative correlation.(4) Main factors influencing showed obvious space-time difference, From the time perspective, industrial structure adjustment, the urbanization process has significant influence to the development of urban construction land in2007, The greenbelt area per capita effect on construction land expansion is remarkable in2002. The Different is that road area per capita in2011to around the city construction land expansion effect is remarkable. From the space perspective, Industry structure effect on construction land expansion of northwest region of hubei is significant。 Such as shiyan, enshiand so on. The urbanization rate, the greenbelt area per capita, per capita road area of hubei province city circle effect is not significant;(4) Per capita green area biggest influence on urban construction land expansion. Eventually change trend of the construction land expansion in the city in hubei province is made up by the positive role of urbanization rate and the per capita green area、 and negative role of road per area. and the land expand is a result of the combined action of various driving forces. According to the related research conclusion, put forward the research countermeasures are as follows:(1)According to the new requirement of urbanization, and guide cities regional coordinated development;(2) Lead the economic development, optimizing industrial structure;(3) ncrease the infrastructure construction and improve the level of traffic;(3) Expand the green area, set up the sustainable development.
