摘要
为了探讨台湾相思群落生长发育与气候特征的关系,选用11个位于大屿靠海一侧不同地点的台湾相思群落研究对象。通过2016年4—12月对台湾相思标记枝条的生长状况进行长期监测。观测结果表明:11个样点受盐害叶片占比为1.16%~51.48%,受虫害叶片占比为30.27%~59.78%。植株大多受到盐害与虫害的干扰,花数量和花蕾数量处于一个较低的水平。由植物生长状况与气候特征的相关性结果可知,风向和风力随月份变化而变化,12月风力最高达5.93m/s。月份和风向与受盐害叶片占比、受虫害叶片占比均呈现极显著相关性。在开展海岛植被生态修复时,需要注重冬季养护、病虫害防治和筛选抗风、耐盐雾的海岛适生物种。
Under the background of island remediation and restoration of Dayu Island,in order to explore the relationship between the growth and development of climatic conditions and the climate characteristics of Acacia confusa ,eleven Acacia confusa communities were selected as study objects in different locations on the sea side of Dayu Island.Through long term monitoring of the growth of Acacia confusa＇s branded branches from April to December in 2016,the results showed that the proportion of salt affected leaves in 11 samples was 1.16%-51.48%,and the percentage of leaves that were damaged by insects was 30.27%-59.78%.Plants were mostly affected by salt damage and insect pests,and the number of flowers and the number of buds were at a lower level. According to the correlation between plant growth and climatic characteristics,the wind direction and wind force varied with the month, and the maximum wind power in December reached 5.93 m/s.The ratios of month and wind direction to the salt affected leaves accounted,and to the leaves that were damaged by insects were both showed significant correlations.When carrying out the ec ological restoration of island vegetation, We need to pay attention to maintaining in winter,diseases and pests controlling,as well as screening out island species with the character of wind resist ance, salt fog tolerant.
