Marginal Cost - Benefit Analysis Of Land Resource Use Conversion

The land resource is one of the human social and economic development of the most basic means of production, development and utilization of land resources, the development of human society provides the most basic, necessary for the production and living material, the production of these materials not only promotes the progress and development of human society, but also on the survival of human land left a deep imprint, produced by the human production, life and labor mark changed the original appearance of the land, the land ecological environment, by the impact of human activities.Human according to the needs of their own development using land resources and land resources are divided into different uses, including agricultural land, construction land, reserves and other, people according to their intentions, arbitrary expand various uses of land resources, land original appearance gradual y disappeared, but more and more adapt to the to the needs of the development of human society.With the rapid development of human society and economy, the development of land resources utilization degree gradually increased, some economical y developed areas of land resources continuously being exploited, land resources ecological environment conservation function is damaged, even driven by the economic interests of the region, some areas of ecological protection area and cultivated land resources were also converted into a higher economic benefit of construction land resources, land resources ecological damage to the environment is higher, the protection ability of the basic means of production and livelihood of land resources reduced. These are the land resources developed by some regions of our country, and the protection of arable land resources is the result of insufficient attention.Such a model of economic development, although in certain period will lead to the rapid development of the regional economy, but due to the serious destruction of the environmental resources exploitation and ecological environment, agricultural production development basic guarantee function is weak, resulting in regional economic development overall sustainability is weak, and the high cost of resources and environment, severe damage to the environment. Therefore, the orderly planning and regulation of land resources uses is the effective method and way of the economic development and resource environment utilization.This study will use the land resources management transformation as the research target, the environmental cost of development and utilization of land resources in consideration, analyze the marginal cost and benefit the use of land resources conversion to produce, that the main driving force of land resources use change, not only lies in the high economic benefit of land use conversion, the relative value of shadow price changes, but also in the conversion of land use, land resource utilization cost is relatively low, resulting in land use transition the opportunity cost is too high, the land resource development enterprises not fully bear land resources development costs, the cost is narrow, the relative lack of protection of land resources. Cost, regional ecological environment has been seriously damaged.And the right to the use of the land market management system is still urban-rural dual land management, implementation of different modes of transfer of land in the land of different ownership, different ways of land transference have different economic benefits, resulting in land use control system and decision policy means the relative lack of, can not be comprehensive and effective protection of individual use of land resources, especially of arable land resources and ecological environment protection is relatively insufficient.On the basis of this, the Beijing City as the study area, analysis of a large area of the cultivated land resources in Beijing in recent years to the conversion for use in building the resources of the main driving factors, that Beijing land and resources development and utilization of intensive level is getting higher and higher, the output of the land can upgrade the force, but it also leads to the in recent years, the Beijing Municipal Land Resources and agriculture with large surface is converted into construction land, cultivated land resources per capita ownership continued to decrease the main reason, so the construction land will also get rapid development and utilization, and this is leading to the cultivated land resources rapidly reduce the reason.Final y, on the basis of research, it puts forward relevant policy suggestions that land use planning is to protect the land rational utilization, one of the effective supply, is to protect and promote the coordinated development of the regional economy, to realize the transformation of the industrial structure, an important means of protecting the ecological environment. Therefore, we should pay attention to the planning and control of land resources use in the region, plan the regional land resources use, and ensure the regional economic development, and coordinate all aspects of land needs.
