| 摘 要： | 利用1986年和2001年两期TM影像，在GIS支持下，采用人为影响程度的比重和景观指数等多指标比重分析法以及人为影响类型极性分析法，对泰山景观的人为影响程度和景观结构变化作用方向进行定量描述。结果表明，人为影响类型极性分析法可以较理想地定量描述景观结构变化作用的方向和程度。在泰山风观区，景观人为综合极性影响可以划分为5个大类，影响程度可以划分为3个级别。15a来人为综合影响为正极性作用方向，其中Ⅱ级中度影响区影响系数最小，是泰山生态安全决策必须首先重视的区域。

| Abstract: | In this paper, the influence of human activities on the landscape structure at Taishan of Shandong province has been studied.Based on the landscape map compiled with satellite remotely sensed data (TM data in the year 1986 and 2001), the methods of multi-indices analysis and polar analysis were used to quantitatively de- scribe the anthropogenic disturbance intensity and the direction of landscape structural change at Taishan, Chi- na.The results indicated that the method of polar analysis could be used precisely to analyze the effect on land- scape change and detect the direction of anthropogenic disturbance reasonably.At Taishan, the polar anthro- pogenic disturbance on landscape can be divided five types, while the intensity of anthropogenic disturbance can be divided into three grades.The general effect of human impacted during the past fifteen years was positive po- larity.The value of polar anthropogenic disturbance index at the region with medium intensity of anthropogenic disturbance was minimum. |
