摘　　要：为给南宁市及南方相似区域营造景观林提供参考,以广西壮族自治区国有高峰林场景观林为研究对象,运用美景度评价(SBE)法对林分结构因子和群落特征因子进行评价,并对群落特征因子评判值进行标准化处理,构建景观评价模型,分析林分结构因子和群落特征因子对森林景观美景度的影响。结果表明,28块标准地的SBE最大值为1.45,最小值为-1.90,美景度处于中等水平。各影响因子对美景度的影响表现为生活型(30.450%)>色彩差异(26.125%)>轮廓清晰度(21.187%)>混交度(7.340%)>生长状况(7.077%)>株数密度(2.272%)>针阔比(1.617%)>角尺度(1.529%)>林层比(1.223%)>树干形态(1.180%)。群落特征因子和林分结构因子在森林景观美景度评价中发挥重要作用。In order to provide reference for construction of landscape forests in Nanning and similar areas in the south,taking landscape forests of Guangxi state-owned Gaofeng forest farm as research objects,scenic beauty estimation(SBE)method was used to evaluate stand structure factors and community characteristic factors,evaluation values of community characteristic factors were standardized,landscape evaluation model was constructed,and influences of stand structure factors and community characteristic factors on forest landscape scenic beauty were analyzed.Results showed that maximum SBE value of 28 plots was 1.45 and minimum SBE value was-1.90 and scenic beauty was at medium level.Order of influences of different impact factors on scenic beauty was life form(30.450%)>color difference(26.125%)>contour clarity(21.187%)>mixed degree(7.340%)>growth status(7.077%)>plant number density(2.272%)>conifer-broadleaf ratio(1.617%)>angular scale(1.529%)>stand level rate(1.223%)>trunk shape(1.180%).Community characteristic factors and stand structure factors played important roles in evaluation of forest landscape scenic beauty.
