摘    要:基于1970、1980、1990、2000和2008年五期的MSS、TM与ETM遥感影像数据,对海河流域1970~2008年土地利用的变化及其驱动因素进行研究,为充分揭示不同土地利用类型转移特征在土地结构整体变化中的地位和作用,利用ARCGIS数据集成分析平台,将不同时段土地利用图叠加,统计不同土地利用类型在1970~1990年与1990~2008年两个比较时段的转移概率矩阵.近30年来海河流域土地利用结构一直是以耕地和林地为主导的土地覆盖格局,园地、工业用地、住宅用地显著增加,耕地和其它用地则明显减少,在定量刻画土地利用变化的基础上,初步探讨了影响流域内土地格局变化的驱动因素,主要为自然因素以及政策导向、产业结构调整、人口增长等社会经济因素.目前海河流域正处于快速城市化阶段,生产性用地快速增长,耕地面积迅速减少,林地面积变化不大,各级土地管理部门应采取切实有效的措施遏制流域内耕地不合理非农化,保证经济效益、社会效益和生态效益协调增长

关 键 词:海河流域  土地利用  土地覆盖  转移概率矩阵

Abstract:Land use/land cover changes of space-time pattern in Yaihe River basin was identified to provide some scientific information for reasonable land use.This paper demonstrated the land use changes and the main driving factors in Haihe river uing the MSS image in 1970,the TM image in 1980 and 1990,the ETM image in 2000 and 2008.In order to fully revealed the position and function of different types of land use transfer characteristics in the whole land structure changes,obtained ARCGIS integrating with data,overlay different time land use map,and counted land use change probability matrix from1970 to 1990 and from1990 to 2008 in the study area.The results showed that from 1970 to 2008 forestland and cultivated land were major elements in the study area,and orchard,industrial land and housing land increased obviously,while cultivated land and unused land decreased largely.At last analysis were used to study the main driving factors of land cover/use.It was represented from preliminary discussion that land use/land cover changes were affected by natural factors and social economic factors including policy orientation,adjustment of industrial structure,and population growth.Haihe river basin is currently in stage of rapid urbanization,productive land increase rapidly,and cultivated land decrease rapidly,forestry area at various levels have not changed nearly.Ugently administration department should take effective measures to rein in the basin,unreasonable non-agriculturalization of farmland to ensure economic benefit and social benefit and ecological benefits coordinated growth.
Keywords:Haihe river basin  land use  land cover  transition probability matrix
