New Framework of Sustainable Watershed Regional Development and Urban Agglomeration for the Asia-Pacific Rim

Abstract

ABSTRACT"Coordinated and green development are both ideas and measures." This research discussed practical and feasible analysis tools for environment and resource framework for the Asia-Pacific Rim. A literature review of water environment social economic system was carried out, and included a discussion of a small and medium-sized urban coordinated development theory. IntroductionWith the advent of the era of network information, big data and cloud platform, such digital watersheds and smart urbans have entered rapid development phase, as digital Haihe River, Yellow River, Yangtze River, Qiantang River and Pearl River; and Hohhot, Dalian, Beijing, Nanjing, Wuhan, Taizhou, Hangzhou, Shenzhen. Meanwhile, in the context of extreme weather, digital watersheds, metropolis, smart middle-sized and small cities' green harmonious and sustainable development issues would be put forward.A global water sustainability perspective focused on regional environment social economic system is different from either a management perspective or an institutional perspective.In the New Normal of China, measures against sewage, flood water, drainage water, water supply and water-saving, namely governance of water's five aspects has been taken in Zhejiang for regional provincial water sustainability, in-stead of expression of ecosystem services, water resources management, water services management, and flood defence principle. Both Yiwu city of Jinhua prefecture-level city and Yuhuan county of Taizhou prefecture-level city of Zhejiang province in China have implemented some pilot projects and have already achieved some performance in water-saving society construction (Li et al., 2009;Li and Yang, 2011). However, since reform and opening-up, complexity of regional environment social economic system has been growing in small and medium-sized cities of Yangtze River Delta, where water shortage due to the deterioration of water quality is quite serious (Li, 2005;Li et al., 2006;Li et al., 2008). A drinking water crisis, caused by blue algal bloom in Taihu Lake due to eutrophication in Wuxi city, Jiangsu province in May, 2007, has suffered great losses, such as increased risk of cancer. The mode for an economic and social system with characteristic of resource sharing, realizing industrialization firstly and marketization secondly, has even to be reviewed due to this above drinking water crisis. Furthermore, dead pigs pulled from rivers in Shanghai had become a hot issue of great both domestic and foreign emotional concerns on a river water environment in 2013. Therefore, water governance in Yangtze River Delta in China has become an urgent problem to be solved arising with rapid urbanization of the area ( Literature Review for Water Environment Resource FrameworkRegional environment social economic systems are connected with a local hydro-logical structure; definitions of environmental flow, of total water withdrawal, and of adaptive capacity from the Southern Hemisphere to the Northern Hemisphere. Environmental flow refers to how much w...
