摘要:

解析“三生空间”碳代谢有助于实现区域“三生空间”要素整合和结构优化,是寻求城市绿色低碳发展的有效途径之一。以昭通市为例,通过计算垂直方向上碳通量,构建水平方向的碳流模型,系统分析了2010—2018年“三生空间”碳代谢的时空分布,利用生态网络分析方法评价了“三生空间”演化对城市碳代谢的综合影响。结果显示:(1)2010—2018年间昭通市垂直方向上净碳通量和水平方向上净碳流均为负值,“三生空间”演化对昭通市碳代谢平衡产生了消极作用,造成碳排放量的增加。(2)“三生空间”用地在碳代谢系统中的生态关系以限制掠夺关系为主,生态空间被生活空间和生产空间挤占,影响了昭通市的碳代谢平衡。(3)整体生态效用函数J的值为0.85,小于1,说明“三生空间”演化对区域整体碳代谢平衡的综合作用是消极的,这与净碳流显示的结果相同。研究结果可为昭通市国土空间利用优化与低碳发展提供理论依据,这种研究方法可为国土空间优化与“三生空间”优化提供前期支持。

Abstract:

Analyzing the carbon metabolism process of "Production-Living-Ecological" space could contribute to achieving the regional elements integration and structure optimization of "Production-Living-Ecological" space, which could help to strive for green and low carbon development. Taking Zhaotong as an example, this research systematically analyzed the spatial and temporal distribution of carbon metabolism in "Production-Living-Ecological" space from 2010 to 2018 through calculating vertical carbon flux between urban system and atmosphere, and building horizontal carbon flows model between components of the urban system. Besides, ecological network analysis was used to evaluate the comprehensive ecological effects of the "Production-Living-Ecological" space evolution on urban carbon metabolism. The results suggested that: (1) The vertical net carbon flux and the horizontal net carbon flows in Zhaotong from 2010 to 2018 were both negative, which indicated that "Production-Living-Ecological" space evolution had a negative influence on the urban carbon metabolism balance, resulting in an increase in carbon emissions. (2) The main ecological relationship of "Production-Living-Ecological" land in carbon metabolism system was restrictive and predatory relationship. Ecological spaces were occupied by living spaces and production spaces, leading to the imbalance of carbon metabolism. (3) The value of whole ecological utility function J was 0.85 (< 1), showing that the comprehensive effect of "Production-Living-Ecological" space pattern change on urban carbon metabolism was negative. This result was consistent with the inference of net carbon flows calculations. The study results can provide theoretical and data basis for the optimization of land space utilization and low-carbon transition in the study area, as well as decision-making support for the development of "Production-Living-Ecological" space.
