title: [Landscape change in Kangbao County of Hebei {rovince].
abstract: Based on RS image TM5 of 1999 and SPOT5 of 2003, this paper studied the landscape change from 1999 to 2003 of Kangbao County, Hebei Province. Logistic regression was adopted to analyze the driving factors, and Kappa index was used to evaluate the accuracy of the landscape classification result, which was 86.72% for 1999, and 89.76% for 2003. The area of cropland in Kangbao County reduced largely, while that of vegetable field, forestland and artificial grassland increased sharply, among which, vegetable field and artificial grassland had the greatest increasing rate. The landscape fragmentation aggravated in the region. The landscape change was mainly caused by the policy of reducing cultivated land, with the main driving factor slope, and the direct driving factor water-heat condition and soil fertility determined by slope aspect.
