摘要
城市绿地作为陆地区域范围内主要的碳汇用地,对实现国家碳中和目标具有重要意义。本文从宏观的区域绿地层面研究了绿地空间格局与碳汇能力的时空耦合关系,并分析了各类绿地的景观格局对整体碳汇的影响,从而优化碳汇用地空间布局,构建高碳汇导向的城市绿色空间规划方法。研究以娄底市为实例,通过遥感解译获取2015、2017、2019、2021年份的碳汇量空间分布以及土地覆盖类型分布,得到区域内碳汇量的时空变化情况。此外,研究运用景观指数量化林地、耕地和草地的空间布局结构和形态特征,对其进行时空变化分析,为未来城市的优化布局模式提供参考。
As the main carbon sink land in the terrestrial area,urban green space is important to achieve the national carbon neutrality target.This paper studies the spatial-temporal coupling relationship between the spatial pattern of green space and carbon sink capacity from the macroscopic level of regional green space,and analyzes the impact of the landscape pattern of various green spaces on the overall carbon sink,in order to optimize the spatial layout of carbon sink land and construct a high carbon sink-oriented urban green space planning method.Taking Loudi City as an example,the study obtained the spatial distribution of carbon sinks and the distribution of land cover types in 2015.2017,2019,and 2021 through remote sensing interpretation,and obtained the temporal and spatial changes of carbon sinks in the region.In addition,the study uses the landscape index to quantify the spatial distribution structure and morphological characteristics of forest,crop and grassland,and analyzes their temporal and spatial changes to provide a reference for the optimal layout mode of future cities.
