摘　　要：研究生态系统服务权衡与协同关系的时空分布特征及其驱动机制,对生态系统管理和资源配置优化具有重要意义。本文应用InVEST模型量化了2000-2020年江西省生境质量、碳储量、产水量、氮磷输出和土壤保持等生态系统服务,采用Spearman相关分析及地理回归加权方法来确定生态系统服务权衡与协同关系,并运用随机森林探究生态系统服务及其权衡/协同效应的主要影响因素。结果表明:2000-2020年江西省生境质量相对稳定,TP和TN输出量呈上升趋势,碳储量呈微弱下降趋势,产水量和土壤保持量则呈先增后减趋势;在空间上,全省生境质量、碳储量和土壤保持量均呈“中间低四周高”的地理格局,TP和TN输出量则相反;生境质量与碳储量、生境质量与土壤保持量以及碳储量与土壤保持量间呈显著性协同关系,而TN输出量与生境质量、碳储量及土壤保持量则呈显著权衡关系;GDP、降水量和坡度分别为生境质量、产水量和土壤保持量的最主要影响因素,而到河流的距离是TP和TN输出量的主要影响因素;生态系统服务间的权衡(协同)强度受降水、到河流距离、到居民点距离、海拔、温度和人口数量共同作用。Understanding the spatiotemporal variations and driving factors of trade-offs and synergies among ecosystem services is of great significance for ecosystem management and resource allocation optimization. In this study, the InVEST models were used to quantify ecosystem services in Jiangxi Province from 2000 to 2020, including habitat quality, carbon storage, water yield, total nitrogen(TN) and total phosphorus(TP) outputs, and soil conservation. The trade-offs and synergies among ecosystem services were determined by Spearman correlation analysis and geographically weighted regression, and their determinants were further identified by random forests. The results showed that habitat quality of Jiangxi Province remained relatively stable during the study period. The TP and TN outputs showed an increasing trend. Carbon storage showed a slight decreasing trend, and water yield and soil conservation increased but followed by decreasing trends. Habitat quality, carbon storage and soil conservation exhibited spatial patterns of “low in middle and high in the periphery”, while TP and TN outputs were opposite. There were significant synergies between habitat quality and carbon storage, between habitat quality and soil conservation, and between carbon storage and soil conservation. There were trade-offs between the outputs of TN and habitat quality, carbon storage and soil conservation. Gross domestic product, precipitation and slope were the determinants on habitat quality, water yield and soil conservation, respectively. The distance to river was the driving factor for the TP and TN outputs. The intensities of trade-offs/synergies between ecosystem services were jointly regulated by precipitation, the distance to rivers and settlements, elevation, temperature and population.
