本文对浙江省舟山市普陀区基岩海岸的几个主要树种进行了初步的调查研究。结果表明,香樟、湿地松、柏木这3个树种在该地区生长良好,胸径、树高、蓄积的年生长量均大于马尾松及黑松,林分生产力较高。这3个树种的胸径生长呈正态分布,为稳定的群落结构。因此,在基岩海岸发展这3个树种有很大潜力,可作为替代马尾松及黑松在基岩海岸造林的优良树种,为因地制宜地选择树种和营林方法提供了理论依据。
This paper conducted a preliminary investigation of several major tree species along the bedrock coast of Putuo District, Zhoushan City, Zhejiang Province. The results showed that the three species of camphora, slash pine and cedar grow well in this area. The DBH, tree height and accumulated annual growth were higher than those of Pinus massoniana and Pinus thunbergii, and the productivity of the stand was high. The diameter growth of these three species showed a normal distribution, which was a stable community structure. Therefore, the development of these three tree species on the bedrock coast has great potential and can be used as an excellent tree species instead of masson pine and black pine for afforestation on the bedrock coast, providing a theoretical basis for selecting tree species and silviculture methods according to local conditions.
