Environmental status and management in Chiba Prefecture

Chiba Prefecture is located in the east of Tokyo Metropolis. A large scale development of industrial and residential areas began in the late 1950s until then the main industries of the prefecture were agriculture and fisheries. During the past 30 years rapid industrialization and urbanization took place resulting in occurrence of various environmental problems.In an attempt to establish a better environment condition towards 21st century Chiba Prefecture has made Environmental Plan which all the municipal governments, enterprises and inhabitants should observe to realize better environment.

Status of China's Geological Survey and Geological Environments in 2013

With the approach of the 45th World Earth Day,China＇s Ministry of Land and Resources issued the status of the Chinese geological survey and environments on 22nd April 2013.Regional geological survey in 2013 achieved new results-（why was oceanic in twice？） polar and oceanic expedition were fully completed,a national census of geography was begun,and the security capacity of mapping geographic information was enhanced.A new idea for integrated geological survey and scientific research was proposed to enhance marine geological surveys and to improve service capabilities.

Environmental Impact Assessment of Constructed Wetland in the Jiaohe River Estuary of the Songhua Lake

Wetland plays an extremely important role in economy and ecological environment,and the construction of constructed wetland also has a certain impact on the environment.Via the evaluation on environmental status of constructed wetland,the main environmental problems are found out,and the impact of construction of constructed wetland project on local water environment and ecological environment is analyzed,and evaluation conclusion is obtained.

The Enlightenment of the Present Situation of Marine Environment in Zhejiang Province to the Relevant Development Requirements in the New Period

In the new era,the development level of marine industry in Zhejiang province has been improved rapidly,and a series of marine development concepts and requirements have been implemented one after another,which plays an important role in improving the current situation of marine environment.With the deepening of marine development,the current situation of marine environment in the new era has become complex and diverse.How to make the relevant concepts and requirements of marine development to cope with and adapt to various new problems in the development process has become the key to promote the continuous improvement of marine development level.

A Scalable Synthesis of Multiple Models of Geo Big Data Interpretation

The paper proposes a scalable fuzzy approach for mapping the status of the environment integrating several distinct models exploiting geo big data. The process is structured into two phases: the first one can exploit products yielded by distinct models of remote sensing image interpretation defined in the scientific literature, and knowledge of domain experts, possibly ill-defined, for computing partial evidence of a phenomenon. The second phase integrates the partial evidence maps through a learning mechanism exploiting ground truth to compute a synthetic Environmental Status Indicator (ESI) map. The proposal resembles an ensemble approach with the difference that the aggregation is not necessarily consensual but can model a distinct decision attitude in between pessimistic and optimistic. It is scalable and can be implemented in a distributed processing framework, so as to make feasible ESI mapping in near real time to support land monitoring. It is exemplified to map the presence of standing water areas, indicator of water resources, agro-practices or natural hazard from remote sensing by considering different models.

Development trends of environmental protection technologies for Chinese steel industry

Chinese steel industry has made significant progress on reducing fresh water consumption and CO_2/SO_2/COD（ chemical oxygen demand） /dust emissions,and improving comprehensive utilization of solid waste. Some steel companies have become topped worldwide. However,due to the large output quantity of crude steel,the whole steel industry is still a huge source of pollutants. At present,environmental protection standards are encountering challenges of lack of technical support,taxation policy and other issues. Steel industry is currently facing enormous environmental pressure. The development trends of environmental protection technologies were studied by summarizing different development stages. To realize the development targets,the industry needs to carry out its research with independent intellectual property rights,develop comprehensive management systems and establish ecological chain with other industries. This can not only raise the level of environmental protection in a broader range,but also improve the energy efficiency of iron and steel plants and increase added value of waste utilization. Finally,23 environmental protection technologies were proposed and 4 new environmental protection practices were studied.
