促进城市化与森林生态安全的协调与共生,对于促进区域绿色可持续发展,实现排放峰值和碳中和目标至关重要。然而,城市化与森林生态安全之间的耦合协调关系及其影响机制尚缺乏深入的分析。根据长江经济带844个县的数据,研究了城市化与森林生态安全耦合协调度的空间差异及其影响因素。结果表明:i)城市化指数存在明显的空间差异,森林生态安全指数,综合指数,长江经济带的耦合度和耦合协调度。其中,耦合协调度的空间格局与城市化指数具有较强的一致性,也就是说,城市化指数较高的地区也具有较高的耦合协调度。ii)基于耦合特征识别,发现249个“问题地区”主要位于云南省,贵州省东南部,安徽省中部,和江苏省中东部。城市化协调发展滞后是其形成的主要因素。iii)在社会经济指标中,人口结构(0.136),人均金融机构年末贷款余额(0.409)和人均固定资产投资(0.202)均对耦合协调度产生正向影响,而位置条件(-0.126)有负面影响。在自然指标中,土壤有机质(-0.212)和温度(-0.094)对耦合协调度有负面影响。iv)在协调发展过程中,有必要增加财政投入和金融支持,积极制定吸引人才的政策,加强生态文明教育和宣传,发展绿色循环经济。上述措施可促进长江经济带城镇化与森林生态安全的协调发展。
Boosting the coordination and symbiosis of urbanization and forest ecological security is notably critical for promoting regional green and sustainable development and achieving emission peak and carbon neutrality goals. However, there was still a lack of in-depth analysis of the coupling coordination relationship between urbanization and forest ecological security and its impact mechanism. On the basis of the data from 844 counties in the Yangtze River Economic Belt, this paper explored the spatial differences and influencing factors of the coupling coordination degree of urbanization and forest ecological security. The results manifested that: i) There were apparent spatial disparities in the urbanization index, forest ecological security index, comprehensive index, coupling degree and coupling coordination degree of the Yangtze River Economic Belt. Among them, the spatial pattern of coupling coordination degree had a strong consistency with urbanization index, that is, areas with higher urbanization index also had higher coupling coordination degree. ii) Based on coupling feature identification, it was found that 249 \'problem areas\' were mainly located in Yunnan Province, southeastern Guizhou Province, central Anhui Province, and central and eastern Jiangsu Province. The main factor for the formation was due to the lag of urbanization in coordinated development. iii) Among the socioeconomic indicators, population structure (0.136), per capita year-end financial institutions loan balance (0.409) and per capita fixed asset investment (0.202) all had a positive impact on coupling coordination degree, while location conditions (-0.126) had a negative impact. Among the natural indicators, soil organic matter (-0.212) and temperature (-0.094) had a negative impact on coupling coordination degree. iv) During the process of coordinated development, it was necessary to increase financial investment and financial support, actively formulate policies to attract talents, enhance the education and publicity of ecological civilization, and develop a green circular economy. The above measures can promote the harmonious development of urbanization and forest ecological security in the Yangtze River Economic Belt.
