摘要
长三角地区是中国经济最活跃、开放水平最高、人口最为稠密的区域之一,探究区域生态系统服务价值时空演变规律及其驱动因素,对于实现长三角地区生态环境共保联治、增强区域可持续发展能力、推动长三角一体化高质量发展具有重要意义。基于1990—2018年长三角地区4期土地利用数据,在定量分析长三角生态系统服务价值变化趋势及各生态系统服务功能权衡协同关系的基础上,综合采用空间相关、热点分析和地理探测方法探讨长三角生态系统服务价值时空分异特征及其驱动因素。结果表明:(1)长三角生态系统服务价值和各生态系统服务功能价值均呈下降趋势,2010年之后下降趋势放缓;2010年之前区域生态系统服务功能权衡度下降、协同度上升,2010年之后协同关系占据完全主导地位。(2)长三角生态系统服务价值空间分布呈现南高北低的空间格局,且呈显著正向空间自相关关系;冷点数量在2010年达到峰值,之后开始减少;热点数量自2000年之后呈减少趋势,但减幅变小。(3)海拔、日照时长和年降水量为长三角生态系统服务价值空间分异的主要驱动因子;一产占比与海拔的交互作用最为明显,q值达0883,自然地理要素与社会经济要素交互作用主导驱动了长三角生态系统服务价值空间分异。
The Yangtze River Delta(YRD)is a region in China with an active economy,a high level of openness,and a dense population.Given the prominence of this region,it is important to explore the spatial⁃temporal evolution of the re⁃gion′s ecosystem service value(ESV)and its driving factors.This is needed to support the joint protection and manage⁃ment of the ecological environment in the YRD,to enhance regional sustainable development capabilities,and to advance the integrated development of the YRD.Using four⁃stage land use data from the YRD for 1990 to 2018,this study included a quantitative analysis of the trends in ESV changes in the YRD,and the trade⁃off and synergies between multiple services.This included a spatial correlation analysis,hot spot analysis,and geodector models to explore the spatio⁃temporal differ⁃entiation characteristics and driving factors of ESV in the YRD.The results show that:(1)Both ESV and ecosystem serv⁃ice function in the YRD showed a downward trend,and this trend slowed down after 2010.Before 2010,the trade⁃offs be⁃tween regional ecosystem services decreased,and the synergies increased.After 2010,the synergies were dominant;(2)The spatial differentiation of the ESV in the YRD showed a pattern of high values in the south and low values in the north,with a significant positive spatial autocorrelation relationship.The cold spot peaked in 2010,and then began to de⁃crease.The hot spots decreased after 2000,but the rate of the decrease declined gradually;(3)Elevation,sunshine dura⁃tion,and annual precipitation were the main factors leading to the spatial differentiation of ESV in the YRD.The interac⁃tion between the proportion of primary industry and elevation was the strongest,with a q value of 0883.The interaction between natural geographical factors and socio⁃economic factors are the main driving forces to the spatial differentiation of the ESV in the YRD during the study period.
