城市历史水系是具有文化意义的历史地段,是城市功能空间和城市生态的重要组成部分。在城市化进程中,城市历史水系的过度开发和错误利用,造成水生态严重失衡,北京历史水系作为一种自然环境资产,其在遏制生态系统恶化方面的作用却被人们忽视。论文以北京市历史水系为研究对象,结合当地水文水貌特征及历史文化背景提出历史水系的四大生态服务功能,深入发掘城市历史水系的生态系统服务功能和价值。以北京历史水系滨水开放空间为研究单元,利用生境绘图以及问卷调查的方式,了解滨水绿色开放空间的生态状况和景观生态问题,提出北京历史水系生态系统服务功能改善提升策略,为历史水系的生态可持续开发利用提供新的思路与方法。
Urban Historical Water System is a historical site of cultural significance and an important part of urban functional space and urban ecology. In the process of urbanization, excessive development and misuse of historical urban water systems have caused serious imbalances in aquatic ecosystems. As a natural environmental asset, historical water systems in Beijing are neglected in their role in deteriorating the ecosystem. Taking the historical water system of Beijing as the research object, this paper proposes four major ecological service functions of historical water system according to the local hydrological and water features and historical and cultural backgrounds, and deeply explores the ecosystem service functions and values of urban historical water systems. Taking the waterfront open space of historical water system in Beijing as the research unit, this paper used the habitat drawing and questionnaire survey to understand the ecological status and landscape ecology of the open waterfront green space, and proposed the strategy of improving and upgrading the service functions of historical water ecosystem in Beijing. Ecological sustainable development and utilization of new ideas and methods.
