基于Chapman-Richards生长模型的城市人工林碳积累特点和影响因素研究——以上海外环绿带为例
Monoculture exhibit early advantage in carbon sequestration,but broadleaf mixed forests provide greater long-term carbon sink potential:20 years'evidence from Shanghai Green Belt
在碳中和以及城市化的背景下,准确量化城市森林的碳汇效益以及确定合适的树种和管理方法以实现可持续的碳汇潜力,是亟待解决的科学问题。本研究探讨了中国城市化程度最高的城市之一——上海的城市森林碳汇的动态和驱动因素。基于上海外环绿带 5821 个林地小班数据,通过空间替代时间的方法,构建非线性混合效应模型,对 8 个典型林分类型(包括混交林和纯林)的碳积累总量和生长速率进行了量化和比较。在此基础上,通过单变量条件因子分析,定量化区分了自然和人为因素对碳积…查看全部>>
In the context of carbon neutrality and urbanization,there remains a notable research gap concerning the carbon sequestration benefits of urban forests and the identification of suitable tree species and management approaches to achieve sustainable carbon sequestration potential.This study examines the dynamics and drivers of urban forest carbon sequestration in Shanghai,one of the most urbanized cities in China.A comprehensive field inventory dataset spanni…查看全部>>
