A Study On The Evaluation Of Construction Land Intensive Utilization In Hanzhong City

Land is the basic substance sustaining for existence and development of human, and the important non-renewable resources.In recent decades, With the rapid development of the socio-economy, along with the growing industrialization and urbanization, the demand of construction land has been increasing year by year, but at the same time, the land use ways are relatively extensive in our country, the use benefit is low, and the contradictions between supply and demand of land are sharp, which limites the development of future socio-economy, so we need to find a practical way of economical and intensive land use.Currently, the economical and intensive land use has became the inherent demand of implementing the concept of scientific development and promoting a conservation-minded society construction, the basic approaches of further strengthen macro-control and accelerate economic restructuring and change of the pattern of economic growth. And what's more, the economical and intensive land use can alleviate the contradictions between supply and demand of land, improve the effectiveness and scientific of overall planing of land uses.This text is based on a new round of land use planning, and the absorption of advanced theories, research methods and practical investigation in the domestic and international. Take Han zhong city for example, establish a conservation-minded society and promote the fundamental changes to the way of land use, ensure the smooth operation of socio-economy and sustainable development, according to the principle" combined with the connotation and extension, mainly by tapping connotation, and make good use of the level of intensive land use",to research the economical and intensive land use of Han zhong city, the text is divided into six parts as follows.The first part of this paper introduces the connotation, background and meanings of the economical and intensive land use, analyze the theoretical basis of economical and intensive land use, and summarize the relevant research and achievements of intensive land use, on this basis, the paper expounds the main research contents and research methods and ideas.In the second part, the basic situation of construction land use of Han zhong city is deeply analyzed. Firstly the analysis of the development change rule of construction land, the interrelationship of socio-economy development and the change of land use,the consumption trend of the important resource such as agricultural especially the cultivated land because of construction land expansion.the proportional relations of the appropriation of land for construction and the internal factors of the influence of the relationship.Summarize the basic law of under the trend of current social economic development, construction land scale expansion, and analyze the land resources pressure.Then research the social economic indicators reflected the level of land intensive use, define the relationship of indexes of intensive use level, and put forward the reasonable evaluation index system, evaluate the construction land intensive use level of Han zhong city each area county from the macro and micro levels.In the third part of the paper mainly analyze the potential of source types of intensive construction land use and potential influence factors, according to the standard of economical and intensive land use and idle land survey, based on economic growth, technical progress, and safeguard measures, calculates the potential of the intensive inventory construction use.In the fourth part, according to the development of the social and economic and the improve of the intensive land use level, In the situation of standard of intensive use, based on the length of time of the planning, forecasting the scale of construction land of Han zhong city. According to the principle of utilizing stock land, the release speed of potential of capital construction land intensive use, compared with the need of construction land, Overall arrangement of stock and new construction land, and new construction land, and puts forward the scale and control of all kinds of new construction land.The fifth part is proposed to promote the policy measures of the economical and intensive land use based on the basis of the first four parts.The sixth part summarizes the main research results, clarifies the characteristics and innovations in the research, and points out the problems and the further perfecting.
