Effect of anthropogenic disturbances on the temporal-spatial changes of landscape patterns at Taishan Mountain

Based on the Landsat TM images and field survey data,the changes of altitude variation of landscape diversity,landscape heterogeneity and landscape dynamics from 1986 to 2001 in eight anthropo-disturbed regions of Taishan Mountain were studied with the aids of 3S techniques.The results indicate that the ratio of landscape patches change caused by human disturbance in south region is higher than that in the north region.The change of landscape structure in south region is obvious during the past fifteen years,and little changes happen in the north region.The change of landscape diversity is mainly manifested in the high altitude (＞900m) of north region and the low altitude (＜900m) of south region.The results also indicate that the anthropogenic disturbance is the basic cause leading to the division of landscape patches.Landscape structure in the studied area has an obvious spatial-temporal variation characteristic.The change of landscape pattern characteristics is related to the intensity of anthropogenic disturbances.
