摘要
以湛江市高桥红树林国家级自然保护区红树林植物红海榄为研究对象,选择叶面积指数(LAI)、树高、地径、冠径、枝下高等指标开展调查,运用半方差函数分析,选择球状模型拟合检验红海榄叶面积指数的空间结构性,并进行叶面积指数与树冠体积的相关分析。结果表明:红海榄的叶面积指数在空间上存在中等空间自相关性;叶面积指数与树冠体积存在显著的正相关性;迎潮面的叶面积指数高于背潮面。
Mangrove plant of Rhizophora stylosa in the Gaoqiao National Mangrove Nature Reserve on Zhanjiang Municipality,Guangdong Province was studied.The correlations between the leaf area index（LAI） and the plant crown volume were analyzed by surveying the LAI,the plant height,the basal diameter,the crown diameter,the height of the lowest branches,then by conducting the semi-variance function analyses,and testifying the LAI spatial structure of R.stylosa plants by simulating the spherical mode1.The results showed that the LAI of R.stylosa plants was spatially auto-correlated at medium level in space structure.There was significant positive correlation between LAI value and the crown volume,and the R.stylosa LAI values of the wind ward side of the tide were higher than those of the lee ward side of the tide.
