摘要
以大兴安岭地区森林资源为研究对象，建立了一个包含19个指标的综合评价指标体系。以2008年森林资源调查数据为基础，计算得到各评价指标的实测值，并对其进行无量纲化处理，基于层次分析法对大兴安岭地区的森林可持续经营进行综合评价。结果表明：大兴安岭林区森林可持续经营的综合评价指数为0．848；大兴安岭林区森林资源总体上处于可持续发展状态。森林生物多样性保护指数为0．791，森林生产力指数为0．874，森林健康指数为0．871，其中森林生态系统多样性、人工林中混交林的比例、有林地单位面积生长量和龄级结构是制约大兴安岭林区森林可持续经营的主要因素。
Abstract
With the forestry resources in Daxing ’an Mountains area, we set up a composite evaluation system with 19 indicators. With the survey data of forest resource in 2008, we calculated the actual value of each evaluation object and made it non-dimensional .At last, we comprehensively evaluated the sustainable forestry management in Daxing ’ an Mountains by AHP . The comprehensive evaluation index of Sustainable Forest Management in Daxing ’an Mountains is 0.848.The forestry re-sources of Daxing ’ an Mountains area is in sustainable development on the whole .The index of the forestry biodiversity pro-tection is 0.791, and the forestry productive index is 0.874.The forestry healthy index is 0.871.The main factors restricting the forestry sustainable management of Daxing ’ an Mountains area are forestry ecosystem diversity , the proportion of man-made forest in mixed forest , the growth of unit area in forest and aging structure .
