从地理学最高层面的科学难点问题一“综合性”出发，本文阐述了土地利用变化是人地关系地域系统研究的核心领域的观点。并从人文地理学的视角，解析了土地利用变化驱动机制的三个重要内容：消费需求拉动、经济效益驱使、以及协调发展理念作用等；提出了规制、对策的经济评价、以及环境伦理等三个人文地理学研究土地利用变化的新命题。 |

It is known that geography have synthetical and regional attributes. The geographic environment, the study object of geography, consisting of hydrosphere, noosphere, atmosphere, geosphere and biosphere, is a complex system composed of all kinds of physical and human phenomena on the earth surface, so geography is synthetical subject having physical science trait and social science trait, in the view of theoretic system or methodology. In the course of geographical development, synthetical study is the most difficult problems in geography all the time. From the point of synthetical study, the land use is the key field of studying relationship between human and geographic environment. The dominant driving factor of land use change can be divided three type:consumption demand, the drive of economic benefit and the effect of harmonized development awareness. Before Industrial Revolution, the dominant drying factor is consumption demand. During the period of Industrial Revolution, the first transform of dominant drying factor, from consumption demand to economic benefit, had taken place. At present, the second transform of dominant drying factor is yet to occur.
As far as consumption demand concerned, the food demand always is the most necessary and important. With the increase of population, reclaiming land to supply more food is the general measure. Thus, the farmland has been increased, but the forest land and pasturehas been decreased. The UNEP predicted that the 1/5 of forest existing now would be the farmland or grassland. As far as the economic benefit concerned, the coral mechanism is purchasing the maximum of economic benefit and it resulted succession of industrial structure and urban and rural settlement transform. Different land use follow to Location Rent Rule. The result of the land use with high location rent substitute the land use with low location rent appear some phenomena:more and more farmland became the rural land use; the percentage of economic crops increased evidently; industrial corporation move to suburb; the central part of city became the advanced service including finance and so on from common service district. Under principle of eeting more demand and purchasing maximum of economic benefit, there have a lot of unreason utilization of land use and this caused land degradation, desertification, the loss of species etc. So human begun to emphasize that the model of land use should accord with need of sustainable development.
On the basis of above analysis, this paper put forward three new propositions of the study of the change of land use from the view of human geography: regulation, economic estimate of bylaw and environment ethic. |
