本文通过对大连市市内三区选取六个林分因子进行分析,结合森林生态系统服务功能值进行测算,结果表明:研究区内森林生态系统服务功能值与小班优势树种补偿值呈现正相关关系,生态价值与经济价值有相同趋势,而与海拔、坡度等无显著相关关系;研究区内各地类、森林经营措施、林分起源、优势树种的森林生态系统服务均值呈现显著性差异,而不同土壤质地、土壤厚度、坡向、林种和立地类型的森林生态服务均值无显著差异。
Based on the analysis of six factors selected in the three districts of Dalian and the functional value of forest ecosystem services, the results show that there is a positive correlation between the functional value of forest ecosystem services and the compensation value of dominant tree species in small classes There was no significant correlation between ecological value and economic value, and no significant relationship with altitude, slope and so on. Mean values of forest ecosystem services of all kinds, forest management measures, forest origin and dominant species in study area showed significant differences, Soil texture, soil thickness, aspect, forest types and site types of forest ecological services mean no significant difference.
