摘要
基于巫山县解析木、测树样地及规划设计调查小班资料,以优势木平均高作为衡量林地生产力的指标,采用等级系数法建立林地生产力指数与土壤质地、土壤厚度、坡度和坡位的回归关系,以小班为评价单元对全县林地质量进行评价,并提出相关经营建议。
Based on tree stems analysis data, tree measuring sample spots data and forest surveying plots data for planning and designing, using average height of dominant tree species as the index of forestland productivi- ty, the regression models of the forestland productive index and soil texture,thickness of soil,slope and slope- position was established with the grade coefficient method. The evaluation of forestland quality were made for all forest surveying plots in Wushan county, as well as management suggestions were put forward.
