Based on CITY green model,carbon storage per hectare,carbon sequestration and pollution removal of urban forest were analyzed.
城市森林效益是城市森林建设和规划的重要依据,为寻求城市森林效益差别的原因,采用抽样调查方法,对沈阳三环内城市森林213块样地进行实地每木调查,在基于CITYgreen模型基础之上对城市森林所产生的碳密度、固碳率以及污染物净化效益进行对比分析,结果表明:等密度等胸径条件下城市森林效益基本趋于多层林>复层林>单层林;平均树高与碳密度之间以及平均树高与污染物净化量之间基本呈现"S"曲线关系;在平均胸径相等的低密度条件下,城市森林效益随密度的增加而增大;混交林随着年龄的增长随密度的增加效益表现出先增加后降低的趋势;单株树木碳密度和污染物净化量均与单株树木三维绿量之间呈现幂函数关系;不同森林类型碳密度和污染物净化量变化趋势为附属林>风景游憩林>生态公益林>生产经营林>道路林;而固碳率为生态公益林>风景游憩林>生产经营林>附属林>道路林。
