基于面积系数法的乡村景观碳模型建构及测度研究——以直山村为例

Research on Carbon Model Construction andMeasure of Rural Landscape Based on AreacoefficientMethod: A Case Study of ZhishanVillage

“双碳”视野下的乡村景观研究与实践是当代风景园林高质量发展的重要面向,乡村景观碳源碳汇量化解析与制图分析是其研究基础与技术途径,以面积系数法构建的乡村景观碳模型及其测度技术研究亟待开展。基于“三生空间”景观要素进行乡村碳源碳汇因子聚类,建立碳源碳汇清单并计算景观要素基础碳量,依托GIS平台关联对应面积、获取碳系数,建立乡村景观碳模型。以直山村为例,根据景观要素SHP图形数据库将碳模型进行制图表达,实现乡村景观要素的碳量集成与测度解析。相关研究为乡村景观要素碳源碳汇联立分析提供了一种可借鉴、可发展的技术框架与测度方法,为乡村景观碳模型系统建构与纵深发展提供研究基础。

"The achievement of carbon peaking and carbon neutrality"has been an important field of contemporary research and practice for rural landscape during the period of high-quality development.The measure and mapping of carbon source and sink for rural landscape are deemed an essential foundation and technical approach.It is worthwhile to construct the carbon model as well as measure technology of rural landscape by virtue of area-coefficient method.The paper takes Zhishan Village as an example,clustering carbon source and sink factors into"Production-Living-Ecological Space"landscape elements.An inventory of carbon is established to confirm the basic carbon amount.The carbon model is then established through correlating with the corresponding areas via GIS and assigning carbon coefficients.Moreover,based on the SHP graphic database of landscape elements,the carbon model is mapped to achieve the carbon measurements.The results provide the carbon source and sink measure of rural landscape elements with a digital framework and method that can be further referenced and developed,as well as a research foundation for rural low-carbon construction and development.
