The report will assess the different scientific approaches associated with water resource engineering, and compare these approaches with respect to human value. The report will focus on the relationship between ecosystem structure and socio technical structure. Ecosystem deals with plants and living things in specific area and the interaction between them, socio technical system deals with the aspects of people, and society as well as technical aspects of organizational structure with respect to the effect on the environment. Ecosystem directly or indirectly affects the society. At the same time, the socio technical system has an impact on ecosystem services in the perspective of consumption and exploitation of recourses. Finally the two systems are dependent on each other. By the application of scientific tools such as Life Cycle Assessment (LCA), Environmental Impact Assessment (EIA), Environmental Risk Assessment (ERA), Performance Indicator (PI), Drivers Pressure State Impact Response (DPSIR), Mellenium Ecosystem Assessment (MEA), etc., some appropriate indicators can be identified corresponding to each approach. LCA focuses on socio-technical aspects whereas DPSIR is environmentally biased. Environmental impact assessment covers both aspects of the system. A matrix combines these methods with the corresponding keywords, and supports in generating a new general model by considering the most weighted indicators. Since each scientific model focuses on some specific aspects, the newly proposed model will give a general view of water environment status. A final comparison is made to recognize relative bias of the newly proposed model with respect to DPSIR model to assess water environment status of the concerning region.展开更多

Using data, we analyze the "sideline effect" and inherent contradiction of transformational cities, research the policy needs for social security and its trend in the citizenization process of the peri-urban farmers. On this basis, we construct the social security policy system that can adapt to the accelerated process of urbanization. Finally, we put forth the following recommendations for the social security policy in the citizenization process of the peri-urban farmers: distinguishing different groups' policy needs for social security; attaching importance to people's dynamic policy needs for social security in urbanization; focusing on the adaptability of social security policy transformation in urbanization; attaching importance to the social psychosocial environment of social security policy transformation in urbanization; achieving the trinity of non-farm conversion, urbanization and citizenization in the process of urbanization; strengthening the government's dominant position in the building of social security policy system.展开更多

Great efforts have been made to deal with these social problems after the "people-oriented" principle was put forward by the Central Government of China in 2003 as an important part of the Scientif ic View of Development. In the field of urban planning, these efforts include to promote social planning at macro level and to encourage community planning at micro level. In spite of that, social considerations should be further strengthened in urban planning so as to create a better living environment and a harmonious society at the same time.展开更多
