长株潭城市群生态系统服务权衡与协同关系的空间异质性及其驱动因素
Spatial Heterogeneity and Driving Factors of Ecosystem Service Trade-offs and Synergies in the Changsha-Zhuzhou-Xiangtan Urban Agglomeration
摘要
Abstract
Different types of ESs have intricate trade-offs or synergies,and these relationships exhibit strong spatial heterogeneity.Understanding spatial heterogeneity and its driving factors is important for sustainable ecosystem planning and management.Using the Changsha-Zhuzhou-Xiantan Urban Agglomeration(CZTUA)as the study area,we first quantified six important ESs(water conservation(WC),soil conservation(SC),carbon sequestration(CS),habitat quality(HQ),food production(FP),and landscape aesthetics(LA))in 2020 using the InVEST model and the Intelligent Urban Ecosystem Management System(IUEMS).Then,the correlation coefficients between these ESs were estimated for each 1 km grid to investigate the trade-offs or synergies and their spatial patterns.Finally,logistic regression analysis was used to identify the factors influencing trade-offs or synergies between ESs.The results showed that 1)the spatial patterns of SC,WC,CS,HQ,and LA were high in the southeast and low in the northwest,whereas FP was high in the northwest and low in the southeast in 2020.2)The trade-offs or synergies between ESs are spatially heterogeneous in the CZTUA.More than 60%of the study area showed synergistic relationships between SC and CS,SC and WC,SC and HQ,SC,and LA,which were mainly distributed in northeastern and southern mountainous areas and western farmlands.Trade-offs between ESs were mainly found in built-up areas and their peripheries.Trade-offs between FP and CS,FP and WC,FP-HQ and FP,and LA covered over 65%of the study area,mainly in the northern plain and southern mountainous areas,and were primarily found in urban and surrounding non-forested areas.3)The spatial heterogeneity of trade-offs and synergies between ESs is influenced by natural and socioeconomic factors as well as management policies.Synergies between ESs are hindered by steep areas.Synergies between regulating,supporting,and cultural services were promoted by increases in temperature,precipitation,and NDVI.However,synergies between FP and other ESs showed opposite responses to temperature,precipitation,and NDVI increase.Socioeconomic development leads to few synergies or trade-offs between ESs.Ecological protection measures promote synergy between the CS and LA,SC and HQ,SC and LA,SC and CS,and SC and WC.关键词
