摘　　要：针对北京西山地区黄栌人工林的现状,提出了内容包括林分密度调整、补植更新苗木与草本植物、林内卫生清理、土壤改良等的黄栌人工林健康经营方案。方案实施后,通过对实施健康经营方案的样地及对照样地的平均胸径、郁闭度、乔木层密度、幼苗更新密度、物种多样性、群落层次结构、病虫危害比率、火险等级、土壤有机质含量9个评价指标的对比监测,从生产力、群落结构、抵抗力(干扰)、土壤状况4个方面评价了林分健康水平的变化。同时对林内小气候和空气负氧离子浓度进行了对比监测,作为健康评价的辅助指标。监测结果显示,实施森林健康经营技术措施的黄栌人工林的健康水平得到了明显改善。To aim at situation of Cotinus coggygria plantation of Beijing Xishan Area, a set of the C. coggygria plantation＇ s forest health management measures were put forward, which including density restructuring, recruiting update seedlings, stand sanitary clearing, soil improving, and so on. After the implement of the project, the nine indexes including the average diameter at breast height, canopy density, tree-density, density of seedlings update, species diversity, phytocenosium structure, worms harm ratio, fire insurance rating, and soil organic matter content, were monitored and compared in the treated plantations and the control plantations. With the assistant of small forest climate and air concentration of negative oxygen ions, the health levels of forest ecosystem treated with the project were evaluated from the four aspects of productivi- ty, community structure, resistance （interference）, soil conditions.. The results showed that the healthy level of C. coggygria plantations implemented the forest health management measures was obviously improved.
