Abstract

Taking Yaoxian County as an example, applying with the Indices of landscape pattern and DEM, this paper studied the relation of vegetation Spatial characteristics and terrain factors, the difference of the landscape pattern under various degree of human disturbance in alp-clough, Plateau, plain and land between ravines, ravine slope land and ravine bottom land .The results showed that: in ravine slope land, ravine bottom land and alp-clough, the natural landscapes were in the absolute dominant position. However, from northwest to southeast, with human disturbance intensity increasing, anthropogenic features of landscapes became more and more outstanding In Plateau, plain and land between ravines, the landscape structure appeared to be simpler with coarse grains and a less rich diversity. Conversely, in alp-cloug, ravine slope land and ravine bottom land, the landscape showed a complicated shape with a relatively richer diversity. This reflected that the impact of human activities to natural landscape behaved a gradually-growing trend from northwest to southeast, in addition ,the paper also shows that vegetation characteristics in different elevation, slope and aspect of slope, are very different and manifest some rules In addition, the paper also shows that in different topography areas, various vegetation appears different hobby to water and With the distance increasing from towns, various vegetation appear different rules.
