摘要
森林自然度是描述森林状态的指标,是指森林生态系统保持原生状态或受人类干扰的程度大小,对其进行评价和等级划分是森林近自然经营研究中的关键环节。研究基于空间尺度,构建白云山森林自然度评价体系,通过格网形式对研究区域进行细化,并对白云山森林自然度进行评价。结果表明：白云山森林自然度指标值大部分处于0.31～0.60和0.61～0.80之间,就其等级而言,属于第三、第四等级,即较低等级;而整个研究区范围内自然度最高的是荷依岭景区、明珠楼景区与摩星岭景区相交的天然次生林群落,自然度最低的是白云山群落的外围度假区。
Forest naturalness is the index for the description of a forest＇s ecological function in maintaining its native state or human disturbance degree. In the study,a forest naturalness evaluation system for Baiyun mountain based on spatial scale is built. The results showed that for the most part,forest naturalness value in Baiyun Mountain is between 0. 31 and 0. 60,or between 0. 61 and 0. 80,belonging to the third and the fourth grades,respectively. The highest naturalness is found in its natural secondary forest communities,which is in the intersection of its Ridge Scenic Area,Pearl Tower Scenic Area and Star Ridge Scenic Area. And the lowest naturalness is found in its holiday resort area,locating in the periphery of the mountain.
