【摘要】：论文借助经验渗透系数法和价值评估方法,通过对吉林省湿地补给地下水服务价值的科学评估,得出吉林省湿地渗漏补给地下水量和价值量,其中每年补给地下水量约99.71亿m~3。不同湿地类每年渗漏补给地下水量大小排序是沼泽湿地(46.40亿m~3)湖泊湿地(26.64亿m~3)人工湿地(21.48亿m~3)河流湿地(5.19亿m~3)。而不同湿地类中,以内陆盐沼每年渗漏补给地下水量最大,达到每年18.60亿m~3,其次是季节性咸水沼泽,每年为14.93亿m~3,而水产养殖场最小,每年仅为0.05亿m~3。对于吉林省具有不同渗透系数的湿地,其每年渗漏补给地下水量也不同。总体合计吉林省湿地补给地下水价值为401.83亿元。不同湿地类补给地下水价值排序是沼泽湿地(186.99亿元)湖泊湿地(107.36亿元)人工湿地(86.56亿元)河流湿地(20.92亿元),而不同湿地型补给地下水价值最大为内陆盐沼湿地(74.96亿元),最小为水产养殖场(0.20亿元)。吉林省湿地补给地下水价值在空间分布上主要集中于3个区域,即以白城市和松原市为核心区域的"沼泽湿地-湖泊湿地-河流湿地"为主的补给地下水区域,以四平市、长春市和辽源市为核心区域的人工湿地补给地下水区域和以吉林市为核心区域的"沼泽湿地-河流湿地"为主的补给地下水区域。论文研究结果能够为吉林省湿地保护、湿地恢复、合理利用以及湿地科学管理提供依据。
[Abstract]:By means of empirical permeation coefficient method and value evaluation method, through scientific evaluation of service value of wetland recharge groundwater in Jilin Province, the quantity and value of groundwater recharge by wetland leakage in Jilin Province are obtained, in which the amount of groundwater recharge is about 9.971 billion mm3 per year. The order of groundwater quantity per year for different wetland types is swamp wetland (4.64 billion mm2), lake wetland (2.664 billion mm3), constructed wetland (2.148 billion mm3) and river wetland (519 million mm3). Among the different wetland species, the inland salt marsh has the largest annual leakage recharge of groundwater, reaching 1.86 billion mt3 per year, followed by seasonal saltwater marsh (1.493 billion mm3 per year), while the aquaculture farm is the smallest (5 million mm3 per year). For the wetland with different permeability coefficient, the amount of groundwater leakage and recharge is different every year. The total groundwater value of wetland recharge in Jilin Province is 40.183 billion yuan. The order of recharge groundwater value of different wetland types is swamp wetland (18.699 billion yuan) lake wetland (10.736 billion yuan) constructed wetland (8.656 billion yuan) river wetland (2.092 billion yuan) and different wetland type recharge groundwater value is the inland salt marsh wetland 74.96. 100 million yuan, the smallest aquaculture farm (20 million yuan). The groundwater value of wetland recharge in Jilin Province is mainly concentrated in three regions, namely, the recharge area of "swamp wetland, lake wetland and river wetland" with Baicheng city and Songyuan city as the core area, and Siping city as the main recharge area. The artificial wetland recharge groundwater area in Changchun and Liaoyuan city and recharge groundwater area in Jilin city as the core area of "marsh wetland and river wetland". The results can provide basis for wetland protection, wetland restoration, rational utilization and wetland scientific management in Jilin Province.
