Spatial Coupling of Carbon Sink Capacity with High-Quality Development Based on Exploitation and Protection Pattern.

The optimization of carbon sink capacity patterns is a scientific basis for promoting the strategic goal of "carbon neutrality". The study aims to reveal the spatial heterogeneity of carbon sink capacity and its relationship with high-quality economic development. A new spatial pattern and supporting system framework for carbon sink land-use (CSL) efficiency were developed in Yunnan Province, China. The coordination level and driving factors between carbon sink capacity and high-quality development were measured using a coupling coordination model and geographic detector model. The results show that the constructed index system can effectively identify the spatial distribution pattern of CSL efficiency at the county and district scale. The development stage of the coupling coordination degree shows a trend of "wide at both ends and narrow in the middle" and the characteristics of coupling and coordinated development type present an "inverted triangle" state. The coupling coordination relationship between carbon sink capacity and high-quality development depends mainly on the regional natural background conditions, economic development, and urbanization level. The findings provide a scientific basis for decision making in the development and protection of territorial space and offer a new perspective for government to facilitate ecological carbon sink capacity and promote high-quality development.
