摘要
近年来,由于湿地取用灌溉水量的增加,目前,黑河湿地正面临着面积萎缩、功能退化、用水矛盾突出的问题。2018年7—8月,项目采用分层随机抽样的方法,以黑河流域甘州区西大湖湿地周边的住户为调查对象,有针对性地围绕四类问题进行了实地调查。对有效的286份问卷,采用spss24.0进行统计分析。结果表明:人们对湿地功能的主观认识水平不高;对湿地的保护意识及保护措施不强;对正在进行的通过开挖毛渠过度取用湿地水的行为意识不到是对湿地的破坏;对湿地可持续发展也没有相关的理解及行为支持。项目进而对研究区域湿地供水能力进行了分析,得出结论:该区域湿地作为周边2 226.8 hm^2农田的灌溉水源,存在严重的水资源供需矛盾。针对研究结果,项目提出了该区域湿地乃至黑河流域湿地开发利用和保护的对策及建议,以供管理人员参考。
In recent years,due to the increase of the amount of water used for irrigation,the HeiHe wetland is facing the problems of shrinking area,function degradation and water use contradiction.From July to August 2018,the project adopted stratified random sampling method,taking households around the Xi-Dahu wetland in Ganzhou district of HeiHe river basin as the survey objects,and conducted field investigation on four types of problems.Spss24.0 was used for statistical analysis of 286 valid questionnaires.The results showed that people's subjective understanding of wetland function is not high.The awareness and measures of wetland protection are not strong;To be unaware of the damage to the wetland caused by the excessive use of wetland water through the excavation of the wool canal;There is also no relevant understanding and behavioral support for the sustainable development of wetlands.The project further analyzed the water supply capacity of the wetlands in the study area,and concluded that the wetlands in the region,as the irrigation water source of 2226.8 hm2 of surrounding farmland,have a serious contradiction between the supply and demand of water resources.Based on the research results,countermeasures and Suggestions for the development,utilization and protection of wetlands in the region and even the heihe river basin were put forward for the reference of managers.
