上海市碳储量时空演变特征及驱动机制
Spatiotemporal evolution characteristics and driving mechanisms of carbon storage in Shanghai
摘要
Abstract
In the context of rapid urbanization,the dynamic evolution of carbon storage in Shanghai is essential for achieving carbon peaking and carbon neutrality goals.This study examined the spatiotemporal evolution characteristics of carbon stor-age by applying the integrated valuation of ecosystem services and trade-offs(InVEST)model to land use data from 2000,2010,and 2020.Through the integration of static and dynamic driving factors,the driving mechanisms behind carbon stor-age changes were analyzed,employing a geographical detector with optimized parameters.The results reveal a declining trend in Shanghai's carbon storage from 2000 to 2020.Areas with reduced carbon storage are concentrated within the outer ring and some coastal areas,while areas with increased carbon storage are mainly found in Chongming Island and parts of the Lingang area.The annually averaged normalized difference vegetation index(NDVI)and the annually averaged population density are the main factors influencing variations in carbon storage.Moreover,the interaction between these two factors exhibits the strongest explanatory power for changes in carbon storage.This study conducts a multi-dimensional exploration of the characteristics and driving mechanisms of carbon storage changes,providing certain scientific reference value for urban low-carbon development and similar research.关键词
