摘要
全球气候变暖是国际社会广泛关注的全球性难题。随着中国城市化水平越来越高,城市中的碳排放也随之增加。如何通过增强城市绿地碳汇功能使城市达到碳氧平衡或缓解城市外林地的碳汇压力成为了迫切需要解决的问题。城市绿地系统作为城市中重要的组成部分,既是调节城市碳氧平衡的关键,又是城市可持续发展的基础。文章概述了城市绿地碳汇功能及相关概念;介绍了现场测定法、样地清查法、生物量模型法和遥感估算法四种城市绿地碳汇功能研究方法;综述了基于碳氧平衡的低碳森林城市构建理论和“三源绿地”城市绿地空间布局理论两种基于碳汇理念的城市绿地理论。分析了当前城市绿地碳汇研究的不足;展望了城市绿地碳汇研究的发展趋势。
Global warming is a global problem of wide concern to the international community.As China becomes more and more urbanized,carbon emissions in cities are increasing.How to make the city reach carbon and oxygen balance or relieve the pressure of forest outside the city by enhancing the function of urban green space carbon sink has become an urgent problem to be solved.As an important part of the city,urban green space system is not only the key to regulate urban carbon and oxygen balance,but also the foundation of urban sustainable development.This paper summarizes the function and related concept of urban green space carbon sink.Four methods to study the function of urban green space carbon sink are introduced,including field measurement,sample land inventory,biomass model and remote sensing estimation.Two urban green space theories based on the concept of carbon sink are summarized,which are the low carbon forest city construction theory based on carbon and oxygen balance and the"three source green space"urban green space layout theory.The deficiency of current research on urban green space carbon sink is analyzed.The development trend of urban green space carbon sink function is prospected.
