حفظ اکوسیستم رودخانه شهری، نگرانی اصلی برای پروژه های مشتمل بر توسعه شهری جدید و بازسازی شهرهای قدیمی به حساب می آید. LID-BMP به عنوان یک روش یکپارچه ابتکاری برای کاهش تاثیرات منفی شهر سازی بر سیستم های آبی درنظر گرفته شده است. در شهر یک مطالعه موردی برای ایجاد سیستم آبی نمایشی بسته با استفاده از تکنولوژی LID-BMP در پروژه ای برای تجدید حیات منطقه فرهنگی انجام شد. نشان داده شد که سیستم آبی بسته توانایی حفظ کمیت و کیفیت آب را دارد. به علاوه، هرچند سیستم متداول لوله کشی آب طوفان در منطقه تنها استاندارد مورد نیاز برای طوفان هایی با فاصله بازرخداد ۲ سال را رعایت نمود، اما بااستفاده از LID-BMP، هیچ گونه سیلاب محلی در طوفانی با فاصله بازرخداد ۵ ساله رخ نخواهد داد. بنابراین با پیاده کردن LID-BMP، ریسک های سیلاب کاهش می یابد. طرح پیشنهادی اخیراً توسط آژانس های دولتی مربوطه محلی تائید شده وحال، سیستم آبی بسته در دست ساخت است.

The Taihu Lake Basin in Southeastern China has one of the highest degrees of industrialization and urbanization in China. However, along with the rapid urbanization and extreme land use changes over the past 30 years, many cities in the Taihu Lake basin such as Suzhou have faced serious urban water system problems. River corridors have been encroached upon, rivers have been truncated, and the numbers of blocked-off rivers and enclosed water systems have increased, all because of urban expansion and retrofit needs (Zhang et al., 2013). Similar situations have occurred in many other cities in China and other countries that have experienced rapid urbanization. Such hydro-modification activities have often resulted in a reduction of streams’ self-purification capacity and ecosystem degradation (Ballo et al., 2009; Du et al., 2012; Moore et al., 2012), which have seriously affected the quality of life and the sustainable development of cities. Urban river restoration to improve the water quality and ecological functions is becoming a concern for the government and the general public all over the world (Mitsch, 2012; Palmer et al., 2014; Hao, 2005). However, urban river restoration is a complex task for local governments, particularly in old historical cities, as itinvolves interactions among administrative agencies with regard to land use, landscape, aquatic environment protection, flood control, etc. (Sun et al., 2011; Loucks and Jia, 2012). An integrated systematic solution that combines knowledge of urban planning, landscape ecology, environmental science, and hydrology is needed. Low impact development best management practices (LID-BMPs) are an innovative, integrated set of methodologies and engineering systems for urban runoff control (Davis, 2005). In addition to their benefits in flood control, LID-BMPs enhance water quality purification, rainwater harvesting, esthetics, and ecology (Dietz, 2007; Jia et al., 2013b). In this context, incorporating an LID strategy in urban river restoration during new urban development or old urban revitalization has become a focus for urban planners, researchers, and managers (Wong, 2002; USEPA, 2004; Jia et al., 2012). Using the opportunity of performing a revitalization projectin the Taohuawu Cultural District in Suzhou, Jiangsu Province, we conducted a case study of LID-BMP technology for stormwater harvesting, treatment, and water quality maintenance for closed urban scenic river systems. The main goal of the case study, which is the focus of the present paper, was to develop a plan that would maintain a sound habitat for aquatic life by providing the required water quantity and quality. The ecosystem restoration plan of the closed urban river systems will be considered for implementation by the local government in the ultimate development and management of the historic site restoration project. 2. Methods 2.1. The study site Suzhou is an important, highly developed historical city in Jiangsu Province in eastern China. After a decade of fast economic development, the local government has begun to work rigorously on water pollution control and urban river rehabilitation projects. In this context, a revitalization project for the Taohuawu Cultural Districtin the Suzhou historical area was proposed by the local government. The Taohuawu Cultural District is the former residence site of Tang Yin, a very famous Chinese scholar, painter, calligrapher, and poet during the Ming Dynasty period, whose life story has become legendary. The location of the Taohuawu Cultural District is shown in Fig. 1. According to historical records, there were once rivers and lotus ponds inthe TaohuawuCultural District. However,these water bodies were buried along withurbanconstruction over time. Recently, the Suzhou municipal government launched a revitalization project to restore the historical landscape, including restoration of the lost river system. Currently, densely-spread private houses surround the Taohuawu Cultural District. It would be very difficult to remove these old private houses in the near future. Consequently,the Taohuawu Cultural District revitalization project is only the Phase I construction of the overall revitalization effort, which includes the restoration of only the part of urban river and lakes located within the project area. Due to these limitations, the restored water system had to be closed, without any connection to a nearby river or other external water supplies in the near future. The master plan for the revitalization project is shown in Fig. 1. 2.2. Research roadmap The aim of the revitalization project was to create a healthy water system with guaranteed high water quantity and quality before its connection to an outer urban river in the future. It involved how to harvest and treat the local runoff by LID-BMPs to provide a water source for the Taohuawu closed water system and how to give the system the ability to maintain water quality. The research plan is shown in Fig. 2.
