Abstract: To approach the spatial heterogeneity of human disturbance is of significance in researching the dynamics of land cover change,especially the characteristics of its directional structure.Jinjiang City is a “hot” region of land use change in Fujian Province,and the land has experienced intense human disturbance.This paper studied the spatial heterogeneity of land use intensity and human disturbance in this city in 1989～2001,with systematic grid sampling method and geostatistics in application.The results revealed that there was an obvious spatial heterogeneity of human disturbance in the study area,especially the directional structure of NE-SW caused by the traffic line from QingyangAnhai.Human disturbance was grown in the whole area,and the administrative centers served as the growth poles.Because of the associated influence of traffic lines and administrative centers,human disturbance was of a pole-axis structure.
