以不同树种林分健康状况比较研究为切入点,以北京西山地区同一时期的油松×侧柏混交林、油松(Pinus tabulaeformis)林、侧柏(Platycladus orientalis)林和栓皮栎(Quercus variabis)林为研究对象.通过构建林分健康评价指标体系,计算林分综合健康指数,分别对不同林分的健康状况进行了分析和比较,探讨不同林分开展森林健康经营的关键环节,同时也从森林健康的角度说明造林树种选择的重要性.研究结果表明:各林分综合健康指数都为正值但数值都不高,这表明目前各林分都处于健康状态,但对外界扰动反应较为敏感,按健康状况排序:油松×侧柏林0.234>栓皮栎林0.186>油松林0.145>侧柏林0.128;从单个指标看,各林分中都有负值指标出现,由此揭示,对负值指标的调整和增加正向指标的指标值是森林健康经营的关键.

Taking Pine × Side Berlin forests, pine forests, oriental arborvitae forests and cork oak forests planted in the same period in the Beijing west-mountainous area as the object, this paper studies forest health conditions of different tree species and different standing forests. Through the construction of the forest health system, and the comprehensive index calculation, the health status of different tree species were analyzed and compared separately. Then we discuss the importance of tree special selection, as well as the key link in forest health management of different tree species. The results showed that the forest health index values are positive but not high, which indicates that the forests are in a good state of health currently, but more sensitive responses to external disturbances are necessary for future improvements in forest health. The health status sorts were, Pine × Side, Berlin 0.234>, Cork oak for-ests0.186,> pine forests 0.145, >side Berlin forests 0.128. Comparatively, some indicators from different forests showed negative values. According to this, it is critical to adjust negative indicator values and increase positive indicator values in forest health man-agement.
