以浙江天目山国家级自然保护区内的近自然毛竹林为对象,基于DEM在群落尺度上分析不同地形条件对毛竹株数和竹壁材积的影响,对单一地形因子分析结果表明:在近自然毛竹林中,毛竹株数随坡度增加有增加的趋势;毛竹株数相对于竹壁材积,对坡向较为敏感;毛竹株数和竹壁材积受地表起伏变化的影响不明显。对组合地形因子分析结果表明:坡向、坡度和粗糙度的不同组合,均会对毛竹的生长和发育产生不同的影响。
Based on DEM, the effects of different topography conditions on bamboo number and bamboo wall volume were studied based on DEM. The results of single topographic analysis showed that in the natural bamboo forest near Tianmushan National Nature Reserve in Zhejiang Province, , The number of the bamboo tends to increase with the slope; the number of bamboo relative to the bamboo wall volume is more sensitive to the slope; bamboo number and bamboo wall volume affected by undulating surface changes. The result of the combined terrain analysis shows that different combinations of slope, slope and roughness all have different effects on the growth and development of Phyllostachys pubescens.
