摘要 在我国林业战略目标处于转型的时代背景下,研究森林健康问题,不仅是完善生态化建设的理论内容,对营林工作的开展也起到了重要作用。本研究在永安市选取了20块具有代表性的标准地,以其中一块作为对照标准地,采用健康距离法,对其森林健康进行评价研究。结果表明,健康标准地有3块,亚健康标准地有9块,不健康和病态标准地共7块。树种组成单一和病虫害是造成森林不健康的最主要问题。其中树种组成单一说明森林结构不合理,也是导致病虫害严重的原因之一。对于不健康和病态的森林要优先治理,受害严重的地区可进行彻底的改造;对于亚健康的森林辅以人工更新,合理疏伐和补植;对健康的森林要继续保持其稳定,加强病虫害防治。这一研究在一定程度上弥补了当地对森林健康研究的缺乏,对日后开展更全面的健康评价研究具有一定的参考价值。 Under the time background of the China's strategic goal of forestly in its transformation, researching the forest health prob- lem is not only to perfect the theory content of ecological construction, but also to play- an important role in the forestry work. The study selects 20 representative standard sites in Yong'an city-, using one of them as the compared standard site, adopting the healthy-distance method to evaluate the forest health. The result shows that there are 3 healthy standard stites, 9 sub-health standard sites, and 7 unhealthy and pathological standard sites . The single plant species and pests and diseases are the most important problems in forest health. The sin- gle plant species embody the unreasonableness of forest structure, which is also one of the causes of pests and diseases. The unhealthy and pathological forests should take the priority and be given to treatment; The affected areas can be thoroughly rehabilitated. For sub- healthy forest, it should be supplemented by artificial regeneration, reasonable thinning and replanting; The healthy forests should be kept stable and strengthen pest control. The study makes up for the lack of local forest health research to some extent, and has certain reference value for future research on comprehensive health evaluation.
