摘　　要：通过对二环林带各标段调查分析,取点采样测量树种生物量,分别在各标段点内选一株平均优势木做解析木进行了分析;针对各标段主要树种的胸径和树高随着年龄的变化,并利用统计分析其生长变化曲线,探索了其生长状况和生长规律。Through investigating on each section of second-ring road forest belt and collecting sample points to measure plant species biomass, an average dominate tree was selected as analyzed tree in each section. According to the changes of DBH （diameter at breast height） and plant height along with the ages in each section, the growth status and rules were studied using statistical analysis and growth curves.
