| 摘 要： | 柳杉Cryptomeria fortunei是浙江天目山国家级自然保护区主要的景观树种。目前，瘿瘤病成为引起柳杉衰退一种非常严重的病害。在调查了天目山不同海拔高度柳杉瘿瘤病害的基础上，测定了对照柳杉和有瘤柳杉的各项生理生态指标。结果显示，随着海拔的升高，天目山柳杉的树龄逐渐增大，瘿瘤病对柳杉相对叶绿素含量（SPAD值）和叶片相对含水率的影响度逐渐增大，对光合参数以及蒸腾速率的影响则呈减小的趋势；随着海拔的升高，对照柳杉的各项生理参数逐渐减小。这在一定程度上说明了柳杉自身的老龄化也是影响天目山柳杉健康进而导致种群衰退的一个重要原因。图2表3参18

| Abstract: | In the recent years, the gall disease has become a kind of very serious plant diseases causing the decline of Cryptomeria fortunei population on Mount Tianmu of Zhejiang Province. This article separately investigated the situation of gall disease and determined degree of relative chlorophyll content （SPAD value）, photosynthetic and water characteristic parameters of both C. fortunei with galls and the ones without galls at 640, 960 and 1 050 meters’s altitudes of Mount Tianmu. The results showed that with elevation of altitudes, the tree ages of C. fortunei on Mount Tianmu increase gradually, the effect degrees of SPAD value and relative water content in leaves of C. fortunei increased gradually as well, but the effect degrees of photosynthesis parameter and transpiration rate reduced, and that each physiological parameter of C. fortunei without galls reduced gradually, which indicated own aging of C. fortunei on Mount Tianmu is also a substantial cause of affecting its health and leading its population decline to a certain extent. |
