Water Environmental Regulations Pertaining to Urban Moats: An Example from the Qinhuai River, Nanjing

Abstract

Moats are an important element of the historical development and management of urban environments in China. As a result of the rapid development of cities and long-term over-exploitation and pollution, problems have arisen in relation to urban moats, particularly with regard to the blockage of river channels, the reduction of river areas, and the deterioration of water quality. Treatment and upgrading of urban moats, in relation to the surrounding city and its rivers, is thus important for the harmonious development of modern cities. This is an important aspect of current urban planning and water conservation that affects the quality of life in cities. In this article we have conducted a case study on the Qinhuai River in Nanjing. Specific measures and achievements in relation to water treatment of the Qinhuai River have been analyzed in the context of enhancing water conservation while taking economic factors into account. We have also undertaken an analysis of management deficiencies in terms of environmental degradation of the Qinhuai River and have made recommendations on future management so as to promote harmonious environment-friendly economic development and the coordination of urban development and public health. The Qinhuai River can be regarded as a case study in which the need to maintain historical Chinese moats must be part of the management of the aquatic environment in modern cities. The aim of this study is therefore to provide a reference for water management in other cities.
