Analysis of Land Use Based on Regional Property of Rock in Miyun County of Beijing

The purpose of this paper is to probe into the type,spatial pattern of land use in each region of rock property and to analze the effect and restraint of the rock property on the land use in Miyun county of Beijing.The used geological map(1∶50,000) of Miyun county of Beijing had regional properties of the rocks s,and was vectorized by actual survey and Arcview GIS.Both maps of local land use and rock property region were united.Seven research areas were analyzed.The results showed that forest land occupied absolute superiority in land use structure of Miyun county,which was related to distribution of rocks.Complete degree of land use type was the highest.Superiority degree is very low in the area of Quaternary System sediments.It is concluded that the land use differences on the quantity structure and spatial pattern were affected to a great extent by the rock property.
