Construction of low impact rainwater managerial urban ecosystem

With rapid urbanization process, the resulting runoff pollution, floods and rainwater recycling had attracted attention. The methods of construction and design of low impact rainwater managerial urban ecosystem were introduced. The theory, integrated management practices of Low Impact Development and principle and design procedure of Low Impact Development site planning and design were analyzed respectively. Natural water cycle could be protected by low impact rainwater managerial urban ecosystem, and it would promote the resource and environment sustainable development.
