【摘要】 应用SPSS16.0数学统计软件,采用定性与定量相结合的方法确定森林健康评价指标体系,包括结构性指标、功能性指标和适应性指标3大类8个指标,使用层次分析法赋予指标权重,基于ArcGIS9.2对八达岭林场121个小班进行森林健康评价。结果表明,该林场78.24%的林分处于健康和亚健康状态,主要由天然阔叶林、天然灌木林和人工针叶林组成。须采取切实可行的森林经营管理措施,提高经营管理水平,发挥森林更大的综合效益。更多还原

【Abstract】 Based on the methods combining qualitative analysis with quantitative analysis,the forest health assessment indicator system is established by using SPSS16.0 software,which includes structural indicators,functional indicators and adaptive indicators.Applying the method of analytical hierarchy process to confirm the index weight,121 subcompartments are assessed with ArcGIS 9.2 for the forest health in Badaling Forest Farm.The results show that 78.24% of the forest stands are in health or sub-health condition.Most of the forests are natural broad-leaved forests,natural shrubs and artificial coniferous forest.Measures must be taken to improve the level of forest management and to produce comprehensive benefits of forest.更多还原
