摘要:
水生态功能的合理分区充分体现了“分级、分类、分区、分期”的水环境管理思想,是开展水环境和水生态系统管理工作的重要基础.本文在综合调查分析松花江流域自然环境特征、水生态因子和社会经济活动影响的基础上,结合松花江流域水生态功能三级分区结果,以ArcGIS软件为平台,运用数据融合技术,对松花江流域的生境维持、水源涵养、生物多样性维持、农业生产维持和城市支撑维持五种水生态服务功能进行重要性等级评价,根据评价结果将松花江流域分为65个水生态功能四级分区.与以往方法相比,本研究运用了数据融合技术,评价因子在考虑自然生态因素的基础上,兼顾社会经济因素对功能区重要性等级的影响,并将多源数据融合,综合考察其对分区结果的协同影响作用,因此,评价过程更加直观,评价结果更加合理和有效.针对分区结果的分析,给出松花江流域水生态系统管理的合理建议.分区结果有助于识别水生态系统的特征与功能状况,为河流健康评价奠定基础,同时,为松花江流域实施水生态系统的科学管理提供了重要依据.

Abstract:
The rational zoning of aquatic ecological function fully reflects the water environment management idea of “grading, classification, zoning, and staging,” which is an important basis for the management of aquatic environment and water ecosystem. In this paper, the characteristics of natural environment, water ecological factors, and socio-economic activities of the Songhua River basin are analyzed by data fusion technology on ArcGIS software. Based on the three levels of aquatic ecological function in Songhua River Basin, the ecological function importance level of five kinds of aquatic ecological function was evaluated, including habitat maintenance, water conservation, biodiversity maintenance, agricultural production maintenance, and urban support. According to the evaluation results, the Songhua River Basin was divided into 65 water ecological functions of level 4 zoning. Compared with previous methods, this study utilized the data fusion technology, which considered the natural ecology and the impact of social economic factors on the function importance level. The process of the evaluation is more intuitive, and the results are more reasonable and effective. Based on the analysis of the zoning results, this paper provides some reasonable suggestions for the management of the aquatic environment of Songhua River Basin. The results can help identify the characteristics and functional status of the water ecosystem, lay a foundation for the river health evaluation, and provide an important basis for the scientific management of the aquatic ecosystem in the Songhua River Basin.
Key words:  data fusion  Songhua River Basin  aquatic ecological function  level 4 zoning  ArcGIS
