摘要
运用北京市"十五"森林资源二类清查数据,以北京市西山林场为例,从森林生态系统的完整性、稳定性、可持续性建立森林生态系统健康快速评价指标体系。使用层次分析法确定指标权重,运用综合评价模型对森林小斑尺度上北京市西山林场森林生态系统健康状况进行了评价。结果表明,(1)北京西山林场367个小斑中,70.3%的小斑处于亚健康状态。(2)确定的3类8个指标,能比较客观地反映北京市西山林场森林生态系统的健康状况,且简便易用,具有一定的科学性和可操作性。
According to forest resources inventory of the Tenth Five-year Plan in and by taking Xishan Forest Farm of Beijing City as an example,a rapid assessment indicator system of forest ecosystem health is established based on the integrality indicator,stability indicator,and sustainability indicator.Indicator weight is determined by applying the method of AHP.By using forest health assessment model,the health assessment in Xishan Forest Farm at subplot scale is studied.Results show that there are 367 subplots in Xishan Forest Farm and 70.3% of them are in sub-health condition.The eight indexes determined can reflect the forest ecosystem health statement of Xishan Forest Farm and they are easy to use,with a certain degree of science and operation.
