江苏省12大湖泊水环境现状与污染控制建议

江苏面积大于50km^2的12个湖泊的水质恶化、面积减少、富营养化、湖泊生态系统退化与湖泊受TP、TN的污染和围湖造田等有关。经济快速发展，第二产业结构偏重，排放污染的总量超过湖泊承载力，湖泊底泥释放N、P及入糊河流携带污染物为造成湖泊环境问题的根本原因。建议调整产业结构，执行严格的排放标准，围绕重点区域、重点行业、重点企业和重点污染源治理，由控制COD为主转为控制COD和N、P并重，引水调控水质，建立湖泊资源数据库和生态系统信息网络，开展湖泊污染物来源分析和富营养化机理研究，开展跨界区域统筹对湖泊综合治理。

Intelligent comprehensive evaluation system using artificial intelligence for environmental evaluation

Environmental evaluation plays a significant role in the development of the culture and economy in modern times. When the environmental condition becomes degraded, the complete evaluation of ecological analysis is highly necessary to evaluate the environment. Hence, the development of a scientific assessment system of environmental assessment is highly significant in the development of the culture and economy. In this research, the present state of environmental evaluation is discussed, and the evaluation system is integrated through a computational process. Secondly, an environmental evaluation system is presented to establish the model in the evaluation process. Further, in this research, Advanced Artificial Intelligence Framework (AIF) for environmental development and protection has been proposed to improve the culture and economy in modern times. Studies reports indicate clear connections between the criteria of environmental assessment, the protection and development of the environment. The practical application of study findings involves establishing specific proposals for reducing pollution and improving the protection of the environment in China.

Simulation and evaluation on the eco-industrial system of Changchun economic and technological development zone, China

Reasonable structure, adaptive patterns and effective regulation of society, economy and environment subsystems should be taken into account in order to obtain harmonious development of urban eco-industrial system. We simulated and evaluated a redesigned eco-industrial system in Changchun Economic and Technological Development Zone (CCETDZ) in the present work using system dynamics and grey cluster methods. Four typical development strategies were simulated during 2005–2020 via standard system dynamic models. Furthermore, analytic hierarchy process and grey cluster allowed for the eco-industrial system evaluation and scenarios optimizing. Our dynamic simulation and statistical analysis revealed that: (1) CCETDZ would have different development scenarios under different strategies. The total population in scenario 2 grew most rapidly and reached 3.28 × 10⁵ in 2020, exceeding its long-term planning expected population. And the GDP differences among these four scenarios would amount to 6.41 × 10¹⁰ RMB. On the other hand, environmental pollution would become serious along with economy increasing. As a restriction factor, positive or negative increment of water resource will occur according to the selected strategy. (2) The fourth strategy would have the best efficiency, which means that the most efficiently development of CCETDZ required to take science, technology, environment progress and economy increase into account at the same time. (3) Positive environment protection measures, such as cleaner production, green manufacture, production life cycle management and environment friendly industries, should be attached great importance the same as economy development during 2005–2020 in CCETDZ.

Circular economy development in China-current situation,evaluation and policy implications

Circular economy (CE), distinguishing from the traditional linear developmental model, is a new mode which stresses recycling resources to save resources, protect environment and achieve economic development. Thus, many countries have made the development of circular economy as a strategy, since it has played an important role in adjusting the industrial structure, changing the way of economic growth, constructing ecological civilization and finally promoting sustainable development. However, to evaluate the level of CE development is rarely seen. China has experienced “11th Five Year” and “12th Five Year” to promote the development of circular economy through the whole country, and have made remarkable achievements. We assessed the circular economy development levels of 31 Chinese provincial regions in 2017 using data envelopment analysis (DEA) in this study. This analysis applied indicators which can well reflect the characteristics of circular economy. Results show that large differences still exist in the development level of circular economy in different regions. 23% of the provinces (e.g. Beijing, Shanghai, Tianjin) are relatively efficient. 70% of the regions being inefficient in scale efficiency show decreasing returns to scale. The overall efficiency of Inner Mongolia ranks last. In addition, this study finds the inhibitors of circular economy development according to the DEA results and proposed suggestions for establishing an effective mechanism to promote CE development. Overall, our research methods and findings may help China and other regions abroad measure the level of circular economy development and promote the development of circular economy
