城市建设用地扩张对碳排放影响的机制探究

A Study on the Mechanism of the Impact of Urban Construction Land Expansion on Carbon Emission

文章聚焦城市建设用地扩张对碳排放影响这一热点问题,探讨二者之间的影响机制。研究发现:城市建设用地可以通过三条路径影响碳排放,即“产、地、人”三路径,且各路径对碳排放的影响方向及程度大小不一。但并不是说这三条路径是相互独立、互不影响的,相反,这三条路径是协调统一、相互影响的,土地非农化对碳排放的影响包含了产业非农化对碳排放影响的一部分,而产业非农化和土地非农化对碳排放的影响最终可以落脚到人口非农化对碳排放的影响。

The impact of urban construction land expansion on carbon emission is focused on to explore the mechanism of the impact between the two.It is found that urban construction land can affect carbon emission through three paths,namely the“production-land-people”path,and each path varies in direction and degree of influence on carbon emission.However,it is not that these three paths are independent and do not affect each other,on the contrary,they are coordinated,unified and interactional with each other.The impact of agricultural land conversion on carbon emission is part of the impact of agricultural industry conversion on carbon emission,and the impact of agricultural industry and land conversion on carbon emission can ultimately be traced to the impact of agricultural population conversion on carbon emission.
