Analysis of Spatial-temporal Differentiation of Land Use Degree Using Factor Analysis on County Regional Scale--The Case of Quzhou County of Hebei Province
基于因子分析法的县域土地利用 程度时空变异分析 ——以河北省曲周县为例

It is very significant of land use degree evaluation to instruct land resource use. In this paper, integrated evaluation on land use degree in county regional scale was made by using factor analysis. By taking Quzhou County as an example, the authors studied the spatial-temporal variance on land use degree in 1985, 1995 and 2000. The result of research indicated: in the period of fifteen years from 1985 to 2000, the degree of land use of ten towns in Quzhou County was greatly increased. Among them, Huaiqiao Town was the most distinct, then Liyue Town, while Henatuan Town was the least. In addition, the degree of land use during this period had distinct spatial character. For example, the degree of land use in the east-middle and west was greater than that in the south and south-east of Quzhou County. At last, considering the trait of corresponding region, the authors analyzed the driving force of degree of land use from five aspects of nature, society, economy, location and technology. It indicated that nature factor was the basic driving forces, and the society, economy and technical factors were the important external driving forces. They offered important instructions to regulate land use in Quzhou County.
