Study On The Land Potential And Use Pattern In Shallow Mountain Area Of Beijing

As natural blocks, mountains located near city are taking the important place of maitaining the whole regional ecological security,while they are resistjing the city from sprawling. Now that we are stepping into a city expansion period, demanding for so much new land to be unbanized. So it becomes a vital task to work out how to proctcet and make use of the shallow mountain area near the central city.Beijing is a tipical example, which located at the foot of the Yan and Taihang-Mountain .As the transition- area between mountain and plain, the shallow mountain area becomes a conflict place whether to be protected or developped. Anyhow, most of the existing study approved to limit this whole area from built-up space, but it ignored the local inner demand of developping and finally has made low-efficiency-protection result.On the base of Beijing none built-up space research, this paper takes the positive view of making use of the area, in order to protect the more important space. From macro-scale view, on the base of the principles of Landscape Ecology theory, it uses GIS space analysis tool to calculate the land potential in this area and select the key lands; From middle scale view, by analyzing the capacity and attractiveness of each micro-terriens, it generalized several land us pattern . Thirdly, it studys the development ecological impact and delimits some restraints for the land use pattern.As McHarg said,"find the inner situablity of each regional landuse, and try to make full use of it by the lowest costs."Finding the usable lands in order to protect the more important ones. Wish this paper could provide some superficial ideas for the protection and development of the shallow mountain area in Beijing.
