摘　　要：探讨生态系统服务之间的权衡与协同关系,对经济与生态的发展具有重要意义。利用中值趋势分析、显著性检验、偏相关系数法等方法,量化贵州乌蒙山区2015—2020年净初级生产力(NPP)、水源涵养(WY)与土壤保持(SC)这三种生态系统服务的权衡与协同关系。结果表明:(1)利用中值分析与显著检验表明,研究区净初级生产力(NPP)以一般增长为主,土壤保持(SC)以一般退化为主,水源涵养(WY)变化趋势和显著变化不明显;(2)从变化趋势面积占比来看,净初级生产力(NPP)以一般增长为主,面积占54%;水源涵养(WY)以一般退化为主,面积占61.17%;土壤保持(SC)以一般退化为主,占67.81%;这表明研究区生态系统服务在2015—2020年间为退化趋势,生态环境改善不明显;(3)利用偏相关系数法可知,净初级生产力(NPP)与水源涵养(WY)以微弱权衡为主;水源涵养(WY)与土壤保持(SC)在空间上呈现北部权衡、南部协同分布态势;净初级生产力(NPP)与土壤保持(SC)在中部与东北部表现协同,而在东北部、西南部和东部的局部地区则是权衡关系;(4)在不同生态系统类型中,只有裸地的净初级生产力(NPP)与水源涵养(WY)呈现较显著协同,而农田、森林、灌木、湿地与城镇生态系统以微弱权衡为主。贵州乌蒙山区的生态系统服务及其相关关系具有空间异质性,需因地制宜地发展生态经济。It is of great significance for the development of economy and ecology to explore the trade-off and synergistic rela⁃tionship between ecosystem services in the study area.This study has used methods such as median trend analysis,significance test,and partial correlation method to quantify the trade-off and synergistic relationship between net primary productivity(NPP),water source conservation(WY),and soil conservation(SC)of three ecosystem services in the Wumeng Mountains of Guizhou Prov⁃ince from 2015 to 2020.The results showed that:(1)median analysis and significance test showed that NPP in the study area was mainly characterized by general growth,while SC was mainly characterized by general degradation.The trend and significance of WY changed were not significant.(2)From the perspective of the proportion of changing trend areas,NPP mainly showed general growth,with an area accounting for 54%;WY is mainly characterized by general degradation,accounting for 61.17%of the area;SC was mainly characterized by general degradation,accounting for 67.81%.This indicated that the ecosystem services in the study area showed a degradation trend from 2015 to 2020,and there was no significant improvement in the ecological environment.(3)Using the partial phase relationship method,it can be inferred that NPP and WY are mainly weakly balanced;WY and SC ex⁃hibited a spatial balance in the north and a synergistic distribution in the south;NPP and SC exhibited synergy in the central and northeastern regions,while in the local areas of the northeast,southwest,and east,there is a trade-off relationship.(4)Among dif⁃ferent ecosystem types,only bare land NPP and WY showed significant synergy,while farmland,forests,shrubs,wetlands,and ur⁃ban ecosystems showed weak trade-offs.The ecosystem services and their related relationships in the Wumeng mountainous area of Guizhou have a spatial heterogeneity,and it is necessary to develop ecological economy according to local conditions.
