| Land is the most important physical basis of existence and development of human being. At present, under the theme of global sustainable development, the study on land use has become a significant study task with epoch-making significance. All over of the world, the great achievement has already been made at land use type, investigation on land resources, land evaluation and land use plan etc. The optimal disposition and pattern of land use are paid close attention, and mainly in land use patterns and types there have been very heavy break-through. Its recent development was summarized and reviewed.Based on this and considering: land use has contacts with soil nutrient; the development of ecology and agrology has already formed the inter-dynamic relation in the last few years, the author sprouted a new idea that the study on land use is carried out in another way. That is to say, land use patterns are designed combining land use modes, soil nutrient with other respects and according as landscape ecology in order to land sustainable use.This research is a preliminary try. Firstly select the adjacent areas of Miyun Reservoir as research object, and carry on a field investigation and sample test. Then analyze the distribution of soil nutrient under different land use, different hill slopes and different structure of land use with SPSS; Quantitatively describe the soil deterioration degree of several land use types on the middle slope with the soil deterioration index; Finally put forward the optimal patterns of land use on the foundation studied of the front result, according to the principle of optimizing land use and by land ecologic design.This paper probed the new thought and method to study land use by the mix of macroscopic way and microcosmic way, combining the qualitative analysis with quantitative analysis. This has important value not only at this district, but also in the other similar area of the North China. |
