沿海防护林主要造林树种木麻黄适生立地条件的研究

Study on suitable site conditions of main afforestation tree species Casuarina equisetifolia in coastal shelterbelt forest

结合3S技术,利用数量化理论Ⅰ,从土壤类型、土层厚度、海拔、坡向和坡度5个因子,对沿海防护林主要造林树种木麻黄在漳浦县的适生立地条件进行测定和分析,并把立地条件划分为5个等级。结果表明:立地适宜等级以Ⅱ级为主,Ⅰ级次之,二者占总面积的91.30%,漳浦立地条件对木麻黄生长较适宜,为沿海防护林适地适树经营提供科学依据。

Integrating with the technology of geomatics, 5 factors such as soil types, soil layer thickness, altitude, aspect and gradient of slope were utilized to assess and analyze the suitable site conditions of the main afforestation tree species Casuarina equisetifolia in coastal shelterbelt forest in Zhangpu based on the first theory of quantification, and the site conditions were divided into 5 grades. The results showed that grade II was the most important suitable site grade, followed by grade I, and the area of those 2 grades accounted for 91.30% of the total. It has been proved that the site conditions in Zhangpu are suitable for the growth of C. equisetifolia, which has offered scientific basis for the operation of suiting C. equisetifolia to site conditions in the coastal shelterbelt forest.
