内蒙古大青山森林健康评价指标体系的构建与初步应用研究

ESTABLISHMENT AND APPLICATION OF THE ASSESSMENT SYSTEM OF FOREST EVALUATION HEALTH IN INNER MONGOLIA DAQINGSHAN

本文通过对内蒙古大青山森林资源的踏查,选取了5个具有代表性的林场作为野外实地调查区域,在科学性、可行性、代表性及独立性原则指导下,以单位面积蓄积量、林龄结构、土层厚度、群落结构、乔木郁闭度、灌木盖度、草本盖度、腐殖质厚度、天然更新状况及病虫害危害程度为评价指标,建立了评价内蒙古大青山森林健康的指标体系,采用层次分析法确定各指标权重,运用评价指标分值法和森林健康综合指数对内蒙古大青山森林的健康状况进行了综合评价。结果表明:内蒙古大青山天然白桦林的健康指数处于0.6-0.79,而油松林、落叶松林及樟子松林处于0.4-0.59,这说明内蒙古大青山天然白桦林的健康状况要好于油松林、落叶松林及樟子松林的健康状况,天然林大部分处于良好健康状态,而相反油松林、落叶松林及樟子松林处于一般健康状态。

Based on preliminary investigation of forest resources in Inner Mongolia daqingshan,five typical forest area,a field survey in scientific and feasible,under the guidance of the principle of independence and representative on unit area,volume,age structure,the soil layer,community structure,trees,shrubs,herb crown density,thickness,natural humus update status and pest damage degree evaluation indexes for evaluating Inner Mongolia,established the index system of daqingshan forest health,using analytic hierarchy process to determine the index weight,using the method of evaluation index scores and forest health index of Inner Mongolia daqingshan forest health was evaluated.Results show that： the health of white birch forest natural Inner Mongolia daqingshan index at 0.6-and in the leaves,lingnan pine and pinus sylvestris var.Mongolica forest at 0.4-0.59,suggesting the Inner Mongolia daqingshan of white birch forest natural health is better than in the leaves and pine and pinus sylvestris var.Mongolica forest health,most natural in good health status,and instead in the pines and pinus sylvestris var.Mongolica and leaves in a general part Linda healthy state.
