城市空间拓展对湖泊水质影响及对策研究——以武汉市为例

IMPACT OF URBAN EXPANSION ON LAKE WATER QUALITY AND COUNTERMEASURES: A CASE STUDY OF WUHAN

探讨武汉市湖泊水质的变化特征与趋势,从理论与实际两个方面,研究了湖泊水质与城市用地拓展的响应关系,分析武汉市水质变化实际与理论计算存在差异的原因,提出了基于湖泊水质的单位水面建设用地承载度概念,并通过归纳,研究武汉市不同湖泊面积下,单位水面建设用地承载度的限值,在此基础上提出城市空间拓展背景下湖泊水质的保护策略。

This paper discusses the changing characteristics and trend of lake water quality in Wuhan, explores the relationship between lake water quality and urban land development from both theoretical and practical aspects, and analyzes the reasons for differences between actual and theoretical calculation of water quality changes. Based on that, the paper proposes the construction land-bearing capacity per unit water surface based on lake water quality. Finally, it puts forward protection strategies for lake water quality in the background of urban expansion.
