为了科学、准确地定量评价林地质量等级,以长沙市林地为案例,提出了林地质量指数这一定量指标。基于小班,采用德尔菲法筛选出土层厚度、土壤类型、坡向、坡位、海拔、坡度、年平均降水量、年平均日照时间、年平均气温9个指标构建长沙市林地质量评价体系,运用层次分析法计算得出各个指标的权重值。结果表明,各指标的权重值分别为0.244 5(土层厚度)、0.1410(土壤类型)、0.074 3(坡向)、0.074 3(坡位)、0.074 3(海拔)、0.141 0(坡度)、0.148 5(年降水量)、0.062 3(年平均日照时间)、0.039 3(年平均气温),表明林地质量指数各指标重要性最大的是土层厚度,其次是年降水量,然后是土壤类型、坡度、坡向、...

In order to scientificly , accurately and quantitatively evaluate forestland quality level , forestlands in Changsha City were taken as a case , and forestland quality indexes were proposed to be a quantitative indicator .Meanwhile the Delphi method was applied to select 9 indexes such as soil depth, soil types, aspects, slope positions, altitude, gradient, annual precipitation, annual average sunshine hours , and annual mean temperature to build a forestland quality evaluation system in Changsha City .Analytic hierarchy process （AHP ） was co...
