Integrating Climate Change Factors into Environmental Planning Innovation of the National 12th Five Year Development Plan towards Climate Change in China

Abstract Effects on sustainable development of climate change have been going further nowadays. National Five Year Development Plan in China should have specific policies on how to take climate change impacts into account through the environmental planning. Key fields distribute in three levels of natural bearing capacity, production system and human settlements, and include seven aspects: ecosystems, water resources, disasters and risks, low-carbon economy, vulnerable departments, urbanization, and coastland.

Parallel programming patterns with granular computing

Parallel programming contributes many methods and techniques to solve problems that require great computational speed and large memory than a single computer. In this paper, we proposed the notion of the parallel programming granulation. We construct a parallel programming pattern with granular computing, and we illustrate how to perform parallel programming and computing with granules. A sample of parallel programming granulation is also given to interpret this notion.

Study on Management and Control of Nonpoint Source Pollution from Urban Surface Runoff

Abstract Urbanization is the dominant form of land-use change in terms of impacts on water quality, hydrology, physical properties of watersheds and their nonpoint source (NPS) pollution potential at present. Urbanization has changed the source, process and sink of urban NPS pollution, especially raised the pollution load of urban runoff NPS in receiving water. Urban runoff pollution is a hot spot of research on NPS. This paper analyzed type, source and harm of the NPS pollutants of urban runoff and its influence on the receiving water. Through estimating NPS pollution load of urban runoff and summarizing the law and characteristics of urban runoff NPS systemically, study on management and control of urban runoff NPS pollution was focused on the application of BMPs (best management practices). It is a fresh methodology that management and control on NPS pollution from urban surface runoff was analyzed by methods of landscape ecology, environmental economics and environmental management. The paper provided a scientific reference for mitigating urban water environment pressure and an effective method for management and control of NPS pollution from urban surface runoff.
