为了明晰徐州侧柏人工林的健康状况，选取群落垂直结构、郁闭度、单位面积蓄积量、林分更新、森林病虫害等级、森林火险指数等10个评价指标，建立评价指标体系。根据该评价体系，采用层次分析法和模糊数学方法，将森林健康分为优质、健康、亚健康、不健康和疾病5个等级，通过样地调查并结合现有相关数据，对60块典型样地进行评价。结果表明：在总评样地中，优质样地占5.00％，健康样地占15.00％，亚健康样地占43.33％，不健康样地占30.00％，疾病样地占6．67％。徐州侧柏人工林的整体健康等级为亚健康，建议通过增加林下木本植物种类和数量、对密度过大的样地进行间伐及开设林窗等途径提高徐州侧柏人工林的健康程度。

In order to evaluate the health status of Platycladus orientalis plantations in Xuzhou Municipality,a forest health assessment index system was formulated by integrating 10 indexes such as the vertical structure of the community,canopy density,standing stock per unit area,forest regeneration,damage grade of forest pests,hazard index of forest fire,etc.According to the health assessment index system,and by means of the analytical hierarchy process (AHP)and fuzzy mathematics method,the forest health status was divided into five classes,i.e.,superior healthy,healthy,sub-healthy,unhealthy and ill.60 typical sample polts chosen from Xuzhou were evaluated by combining the sample plot survey with existing relative data.The results showed that the superior healthy sample plots accounted for 5%,health sample plots accounted for 15%,sub-healthy sample plots accounted for 43.33%, unhealthy sample plots accounted for 30%,and the ill sample plots accounted for 6.67% of the total 60 sample plots.It illustrated that the overall health grade of P.orientalis plantation in Xuzhou was sub-healthy.It was pro-posed to increase the quantity and species of understory woody plants,conduct thinning in the over-densed sample plots,and open forest gaps to improve the health status of the P.orientalis plantations in Xuzhou.
