摘　　要：【目的】动态评估吉林省的湿地调蓄洪水功能价值,为吉林省的湿地安全及湿地环境管理提供理论支撑。【方法】通过机会成本法对吉林省2013、2017年的湿地调蓄洪水功能价值进行对比和评估,分析不同类型湿地及各市的湿地调蓄洪水功能价值变化。【结果】2013和2017年吉林省湿地调蓄洪水功能的总价值分别为2910.10亿元和2685.49亿元,受湿地面积降低的影响,2017年比2013年减少了224.61亿元,对应减少比例为7.72%。在吉林省各市中,湿地调蓄洪水功能价值增加最大的为吉林市(157.47亿元),降低最大的为松原市(−218.77亿元)。虽有部分城市的洪水调蓄功能价值上涨,但吉林省湿地调蓄洪水功能价值整体呈下降状态,而且各市的湿地调蓄洪水功能价值的单位面积(每公顷湿地面积)和人均拥有量均有所变化。在各湿地类型的调蓄洪水功能价值中,沼泽湿地由2013年的510.97亿元增加至2017年的777.60亿元,是唯一增加的湿地类型,而人工湿地、河流湿地和湖泊湿地这3种湿地类型均有所下降。【结论】相比2013年,2017年吉林省的湿地调蓄洪水功能价值整体呈下降趋势,各市和各类湿地的单位面积和人均的湿地调蓄洪水功能价值有明显的地域差异。【Objective】This article dynamically evaluates the floodwater storage function value of wetlands in Jilin Province,providing theoretical support for wetland safety and environmental management in Jilin Province.【Method】The opportunity cost method was used to compare and evaluate the floodwater storage function value of wetlands in Jilin Province in 2013 and 2017,and to analyze the changes in floodwater storage function value of different types of wetlands and various cities.【Result】The total value of floodwater storage function of wetlands in Jilin Province was 291.010 billion yuan in 2013 and 268.549 billion yuan in 2017.Due to the reduction in wetland area,the value in 2017 decreased by 22.461 billion yuan compared to 2013,with a decrease rate of 7.72%.Among the cities in Jilin Province,Jilin City had the largest increase in floodwater storage function value(15.747 billion yuan),while Songyuan City had the largest decrease(21.877 billion yuan).Although some cities have increased the floodwater storage function value,the overall value of wetland floodwater storage function in Jilin Province is decreasing,and the per unit area(per hectare of wetland area)and per capita ownership of wetland floodwater storage function value of each city have also changed.Among the floodwater storage function values of different types of wetlands,swamp wetlands increased from 51.097 billion yuan in 2013 to 77.760 billion yuan in 2017,which is the only type of wetland that increased,while artificial wetlands,river wetlands,and lake wetlands all decreased.【Conclusion】Compared with 2013,the overall trend of floodwater storage function value of wetlands in Jilin Province in 2017 was decreasing,and there were significant regional differences in per unit area and per capita floodwater storage function value of wetlands in each city and wetland type.
