摘要: 在科学性、整体性、代表性和可操作性原则的指导下,从二类调查等数据中选取13个评价指标,构建了杉木速生丰产林健康评价指标体系,并确定了其健康等级划分标准;评价了湖南黄丰桥林场817个杉木小班的健康状况。结果表明: 该林场处于不健康、亚健康和健康状态的杉木小班数分别占总体小班数的24.7%、57.3%和18.0%;幼龄林健康状态较差,中龄林稍好,过熟林普遍处在亚健康状态下,而近成熟林和成熟林健康状况相对较好。该评价结果可为该林场展开相关的健康经营措施提供参考。

Abstract: Based on the principles of scientificity, holism, representativeness, and operability, thirteen evaluation indices were selected from the secondclass forest resources inventory data, and a health assessment index system of fastgrowing and highyielding Cunninghamia lanceolata plantations was constructed. In the meantime, the standard for classifying the C. lanceolata plantations health grade was ascertained, and the health status of the C. lanceolata plantations in 817 subcompartments of Huangfengqiao Forest Farm in Hunan Province was evaluated. Among the subcompartments, those in unhealthy, subhealthy, and healthy occupied 24.7%, 57.3%, and 18.0% of total, respectively. Young plantations had a poorer health condition, middleaged plantations were better, overmature plantations were generally in subhealthy, while nearmature and matured plantations were comparatively healthy. These results could provide reference for the health management of the C. lanceolata plantations in the Farm.
