摘要
结合样地调查和他人对阔叶红松林生态系统相关指标的研究资料数据,利用健康距离(HD)评估法和上文建立的阔叶红松林生态系统健康评估指标体系框架,对不同人为干扰影响的长白山阔叶红松林生态系统进行系统健康的评估实践.结果按顺序依次为20%强度择伐林021<50%强度择伐林044<白桦中成林067<白桦中幼林072<红松人工林074<人工落叶松林077.
On the bases of samples investment and related data collected by others,and with the method of health distance assessment and the ecosystem health index system of Korean pine and broad-leaved mixed forest established in prior paper,this paper attempted to assess the ecosystem health of Korean pine and broad-leaved mixed forest under various human disturbances.The results showed that the health degree was in the order of 20% intensity selective cutting stand (0.21) <50% intensity selective cutting stand (0.44) <middle and mature birch stand (0.67) <youth birch stand (0.72) <Korean pine plantation (0.74) <larch plantation (0.77).
