Human activities, which is an important driving force of landscape heterogeneity, can change the landscape pattern diversity.The spatial-temporal change of landscape pattern has been distinctly defined by many researches recently.A case study of Mountain Tai in Shandong province, eastern China, was performed to develop the appropriate analysis and assessment techniques to quantify the nature and magnitude of landscape structural changes within the upland.Based on the Landsat TM images and field survey data, the changing of landscape diversity with altitude, landscape heterogeneity and landscape dynamics from 1986 to 2001 were analyzed by aids of 3S techniques in eight regions of Taishan.Landscape pattern indices were calculated with geographic information system (GIS) and Patch Analyst program FRAGSTATS software.Results indicated that the relationships between the landscape change and human activities were positively related.The corridors of forest vegetation have been fragmentized, and the patches were isolated and become smaller.The areas of landscape patches were negatively significant related to the intensity of human activity.The areas of patches were small under the high intensity, and large under the low intensity.Human activities were greatly affected on the regional landscape diversity.It revealed that any unconsidered disturbance to the landscape system could be a factor of regional landscape diversity changing.So human disturbance could reach to the area where human did not directly act on.Some effects, due to failing managements or other misplaying, could become an important minatory potential to landscape system.
