Contributions of Natural Carbon Sink Capacity and Carbon Neutrality in the Context of Net-Zero Carbon Cities: A Case Study of Hangzhou

摘要

本研究旨在解决现有城市自然碳汇测量系统存在的不足，该系统常常忽视土壤和小型绿地，阻碍了零碳城市有效空间规划的实施。通过纳入这些要素并采用高分辨率遥感数据，我们构建了一个全面的系统来测量杭州在固碳和储碳方面的自然碳汇能力。研究结果表明，土壤和小型绿地显著影响测量结果和空间格局。杭州的自然碳汇固碳量约占其年碳排放量的 9.87%，表明其在实现碳中和目标中作用重要但有限。因此，减少碳排放的策略对于实现零碳目标至关重要。本研究提出了侧重于巩固现有碳汇和增强固碳能力的গুলির空间规划策略，为更好地建设零碳城市提供更精确的理解。

Abstract

This study aims to address the shortcomings in existing urban natural carbon sink measurement systems, which often overlook soil and small green spaces, hindering effective spatial planning for net-zero carbon cities. By incorporating these elements and employing high-resolution remote sensing data, we developed a comprehensive system to measure Hangzhou’s natural carbon sink capacity in terms of sequestration and storage. Our findings reveal that soil and small green spaces significantly influence measurement results and spatial patterns. Hangzhou’s natural carbon sequestration offsets approximately 9.87% of its annual carbon emissions, indicating its necessary but limited role in achieving carbon neutrality. Therefore, strategies to reduce carbon emissions are integral to the net-zero goal. The study proposes spatial planning strategies focused on consolidating existing carbon sinks and enhancing sequestration, providing a more precise understanding for better net-zero city construction.
