分析了1998年松嫩流域特大洪水发生与湿地丧失和退化的关系,根据湿地所具有的多种功能和效益,提出了松嫩流域水资源管理和防洪体系建设对策。近半个世纪以来,由于人口增长,人水争地,松嫩流域内湿地丧失达70%,湿地质量也发生明显的退化,使本区湿地具有的抵御洪水、调节径流、蓄洪防旱、控制污染、生物多样性保护等方面功能逐渐降低,生态环境趋于恶化。必须从全流域、大系统的角度出发,全面分析上、中、下游的自然、社会、经济条件与湿地的地位,统筹规划,分步实施,封山育林,保持水土,圈地分洪,保护湿地,加固堤防,疏浚河道,整治环境,合理开发,将区域的社会、经济发展建立在可持续的环境基础上。
Based on the various functions and benefits of wetlands, this paper analyzes the relationship between the occurrence of floods and the loss and degradation of wetlands in Songnen Basin in 1998 and puts forward the countermeasures of water resources management and flood control system construction in Songnen River Basin. Nearly half a century, due to population growth and water dispute, the loss of wetlands in the Songnen River reaches 70%, and the quality of wetlands also degenerates obviously, making the wetlands in the region to resist floods, regulate runoff, flood control and drought mitigation and control Pollution, conservation of biodiversity and other aspects of the gradual reduction of ecological environment tends to deteriorate. We must comprehensively analyze the natural, social and economic conditions of the upper, middle and lower reaches and the status of wetlands from the perspective of the whole river basin and the large-scale systems, make overall plans and implement them step by step, close up forests for afforestation, maintain water and soil resources, Dikes, river dredging, remediation of the environment, rational development, and social and economic development in the region on a sustainable basis.
