ZHOU Yan et al(Institute of Land Planning and Information of Guizhou University,Guiyang,Guizhou 550025)  
This paper evaluated the dynamic changes in agricultural land and building land in the typical karst area of the Qingzhen of Guizhou province during 2000~2004,and predicted their change tendencies in the future,applying gray dynamics model.Results showed that comprehensive land use dynamic degree in 2nd levels land types was 0.53% in Qingzhen.Returning cultivated land to forestland resulted in the decreasing of cultivated land and the increasing of forestland.But this transformation mainly occurred within agricultural land.Based on the prediction of land use change,this paper found that,2010~2020, the area of cultivated land decreased by average 1.12% per year.This number was slightly high,when compared with average 1.02% per year during 2000~2004.At the same time,the increasing of building land was mean 5.36‰ per year during 2010~2020,keeping an equal pace with 2.66‰ of the average annual rate from 2000~2004.Above-mentioned data proved that the construction speed of urbanization of Qingzhen was relatively slow,and the construction of urbanization of should be strengthened.
