摘　　要：本文研究中国城市化进程中人口集聚与植被恢复的关系,实证结果显示,人口集聚程度与植被总值正相关。机制分析表明,人口集聚表现出人口增加的地区总面积小于人口退出地区总面积的特征,并且人口退出地区存在着“人退林进”的现象,城市化进程提高了全国层面的植被总量。人口集聚更快的地区,政府会增加林业投资,更快推进退耕还林,从而有利于植被恢复,因而政府行为是实现经济发展与生态文明建设的“双赢”目标的有力保障。We study the relationship between population agglomeration and vegetation restoration in the process of urbanization in China.The empirical results show that the degree of population agglomeration is positively correlated with total vegetation.Mechanism analysis shows that during China's urbanization,the total area of population increasing area is smaller than that of population withdrawing area,and there is a phenomenon of“people withdrawing”and“forest entering”in the population withdrawing area.Therefore,the urbanization process improves the total vegetation at the national level.In areas with faster population agglomeration,the government will increase forestry investment and promote the return of farmland to forest faster,which is conducive to the restoration of vegetation.Therefore,government behavior is a powerful guarantee for realizing the“win-win”goal of economic development and ecological civilization construction.
