environmental monitoring of the Zhujiang Estuary and its coastal waters

Acta Oceanologica Sinica 2002年第2期21卷 275-304页

The Zhujiang (Pearl River) Estuary is a complex water system whose catchments basincovers a very large part of southern China. The large quantity of fresh water carried by the river system flows into the northern coast of the South China Sea through its eight inlets. The Zhujiang River Delta has experienced the fastest economic growth in China during the past two decades. Rapid population expansion and increased industrial development coupled with insufficient waste management turned the Zhujiang Estuary into waste disposal channels just before entering the coastal waters. The water quality of the estuaries and the coastal oceans has become polluted. During the past two years, an intensive study and monitoring efforts of the pollutions of these waters have been made. A systematic and integrated monitoring task including shore-based measurements, shipboard in-situ measurements, and satellite and radar remote sensing surveys has been completed. Comprehensive collection of physical, chemical and biological parameters has been accomplished and a database has been established. Unlike the previous large scale-monitoring task in which the various pollutant concentrations were the objective, the present study aims to understand the process of the pollution from their initial disposal to their final states. The understanding of the processes makes it possible to evaluate the severity of the pollution with respect to the sustainability. Also the objective is to incorporate these processes into the mathematical models from which a predictive capability of the pollution situation can be realized. The present presentation will describe the planning, methodology and the results of this effort.

High Technology Letters 2012年第4期18卷 394-400页

作者：朱昌平 Huang Yon.gliang Shan Minglei Jiangsu Key Laboratory of Power Transmission and Distribution Equipment Technology Hohai University Changzhou 213022 P. R. China

In this paper, an indoor environmental monitoring solution is proposed for the transformer sub- station system by using the ZigBee technology. It mainly analyzes the principle of sulfur hexafluoride sensor based on the acoustic method and puts forward a difference data processing method of single- channel and temperature compensation point at power consumption issues for sensor detection. The method not only reduces the sensor power consumption, but also ensures the accuracy and extends the lifetime of wireless sensor nodes effectively. This paper also analyzes the design of the base sta- tion mode, and demonstrates the running processes of routers and sensors. The feasibility of the pro- posed approach has been testified and proved.

Journal of Geographical Sciences 2002年第2期12卷 40-47页

作者： Deng Xiang-zheng Liu Ji-yuan Zhuang Da-fang Zhan Jin-yan CAS Institute of Geographic Sciences and Natural Resources Research Beijing China (GRID:grid.9227.e) (ISNI:***)

With the development of Internet technologies, Internet Based Information System (IBIS) arises with more advantages: Firstly, it is convenient for users to use owing to the introduction of Internet technologies. Secondly, it benefits greatly the data dissemination and data sharing based on Internet. The most important but not the last is that we can establish the information service network supported by its technologies and the facilities of information highway. So, it would be significant to design IBIS to realize the data collection, sharing and dissemination on Internet. There are many factors affecting regional environment. So it is not easy to realize the integrated environmental monitoring. Given this, we designed the Internet based environmental monitoring information system. By the virtue of the Internet based environmental monitoring information system, the management and storage of environmental monitoring data would be easier, which lays the foundation to actualize the environmental monitoring efficiently.

2023年中国地球科学联合学术年会

作者： Liang Qianyong Ye Jianliang Qin Xuwen Dong Yifei Xie Wenwei Zhong Chao Guo Binbin Guangzhou Marine Geological Survey China Geological Survey

Natural gas hydrate(NGH) is considered as one of the new clean energy sources of the 21st century with the highest potential. The environmental issues of NGH production have attracted the close attention of scientists in various countries. In 2017 and 2020, China Geological Survey successfully organized two rounds of NGH production test in the South China Sea, which set a number of world records, marking a significant leap from "exploratory test production" to "experimental test production", and also indicating an important breakthrough in environmental safety of NGH production test. China Geological survey attaches great importance to the environmental impact of NGH research work. Since 2011, we have research methane leakage, underwater landslides, subsidence, and marine ecological change may cause by NGH exploration. And the marine environment baseline characteristics before the production test in Shenhu sea area have been clarified. In addition, environmental security has also been effectively guaranteed via a comprehensive environmental monitoring system built during the NGH production test. The monitoring system considered methane leakage, seabed subsidence, marine environment and sea surface atmosphere environment. The whole process was monitored via multiple means, in multiple layers, in all domains, and in real time. After the production test, the marine environment tracking survey have been carried out in time to effectively discuss and verify the environmental impact of NGH production test. The results of the two rounds of NGH production test showed that the content of dissolved methane in seawater and the seabed environment characteristics is consistent with the background values, indicating that the two rounds of production test did not cause seabed landslide, methane leakage and other environmental problems, and make no difference on the marine environment basically.
