摘　　要：为促进喀斯特山区生态环境保护和生态系统服务价值的提高。根据贵阳市2009—2018年不同土地利用生态系统的统计数据,采用计量分析方法对贵阳市不同土地利用生态系统服务价值进行研究。结果表明:2009—2018年间,贵阳市生态系统各项服务功能价值表现出下降的趋势,9项生态服务功能中,土壤保育在总生态服务功能价值中变化量最大,娱乐文化变化量最小;不同生态系统服务功能价值占比从大到小的顺序依次表现为林地>耕地>水域>草地>建设用地的变化趋势,林地产生的生态系统服务价值最大,为总价值的70.18%~70.76%,其次是耕地和水域,这3种生态系统产生的服务价值超过了总价值的96.00%,且表现出上升的变化趋势。研究时段生态系统服务功能价值动态变化呈缓慢下降趋势,但下降幅度较小(在6.5%的范围内);2009—2018年间贵阳市人均生态系统服务功能价值占有量总体上呈下降趋势,10年间下降了494.38元,下降幅度为20.87%。In order to promote the protection of ecological environment and the improvement of ecosystem service value in karst mountainous areas,according to the statistical data of different land use ecosystems in Guiyang from 2009 to 2018,the ecosystem service values of different land use was studied by econometric analysis method.The results showed that the value of ecosystem services showed a downward trend from 2009 to 2018 in Guiyang.Among the nine ecological service functions,soil conservation accounted for the maximum variation of the total ecological service function values and entertainment culture accounted for the minimum variation;The order of the proportion of different ecosystem service function value from large to small was forest land>cultivated land>water area>grassland>construction land.The ecosystem service value generated by forest land was the largest,accounting for 70.18%~70.76%of the total value,followed by cultivated land and water area.The service value generated by these three ecosystems exceeds 96.00%of the total value,and showed an upward trend.During the study period,the dynamic change of ecosystem service function value showed a slow downward trend,but the decline range was small(in the range of 6.5%);From 2009 to 2018,the share of ecosystem service function value per capita in Guiyang generally showed a downward trend,with a decrease of 494.38 yuan or 20.87%in 10 years.
