吉林省湿地调蓄洪水功能分析及其价值评估
Flood storage function analysis and value assessment of wetlands in Jilin Province
摘要
Abstract
Wetlands play essential roles in regulating runoff, recharging groundwater, and maintaining the regional water balance, through functions like adjusting the flow rate, slowing the flow velocity, and accumulating water resources. The wetlands in Jilin Province cover a large area and are widely distributed, and have a large impact on flood storage. This paper illustrates the entire feature of the flood storage function of wetlands in Jilin Province by calculating their values and spatial allocations in different regions. The research results show that the flood storage mainly occurs in the central and western regions of Jilin Province, which cover an area of 7000 km2 and an area of 12000 km2 , respectively. The total value of wetland flood storage is 291. 01 billion yuan, The wetlands can be ranked by flood storage value in the following descending order: constructed wetlands ( 121. 872 billion yuan ) , lake wetlands (81. 528 billion yuan) , marsh wetlands (51. 097 billion yuan) , and river wetlands (36. 513 billion yuan) . The cities of Jilin Province can be ranked by flood storage value in the following descending order:Baicheng City ( 79. 852 billion yuan ) , Songyuan City ( 76. 819 billion yuan ) , Changchun City ( 41. 346 billion yuan), Jilin City (30. 208 billion yuan), Yanbian City (21. 494 billion yuan), Tonghua City (17. 506 billion yuan) , Siping City (11. 260 billion yuan) , Liaoyuan City (6. 893 billion yuan) , and Baishan City (5. 632 billion yuan) . In addition, the wetlands in Songyuan City have the largest flood storage value per unit area while those in Biashan City have the smallest value. Baicheng City has the largest flood storage value per capita while Siping City has the smallest value. The spatial allocations of flood storage values per unit area and per capita of different wetland types show significant differences in these cities.关键词
