北方寒冷地区景观水体水质保障技术及对策研究

我国北方地区冬季漫长而寒冷,夏季短暂而温暖,年平均气温低,气温年较差大,开展北方寒冷地区景观水体研究对完善生态系统保护体系及可持续发展具有重要意义。针对北方寒冷地区景观水体环境特征,以牡丹江市南湖水系为例,开展水体水质及水环境特征研究,进行北方寒冷地区景观水体的生态重建与景观修复技术、水资源管理技术、越冬策略研究,并根据工程实践结果,提出北方景观水体水质保障的对策和建议,对北方地区景观水体保护、流域可持续发展具有借鉴意义。

It is characterized by winter long while cold, summer brief but warm, the low annual average temperature, the big annual range temperature in Northern areas. It is important for improving the ecosystem protection and sustainable development to research on landscape of cold regions. For the characteristics of the cold regions to South Lake water system example, water quality and water environment character were studied.Landscape ecological reconstruction of the water body in the cold northern regions and landscape restoration,water management technology, wintering strategy research was also researched. Based on the engineering practice results, the water quality protection countermeasures and suggestions were proposed. It is of significance to landscape water protection of the northern areas, watershed sustainable development.
