Research Topic: Sino-Japan comparative study on changes of water environment and water quality
Outline and Results of Research:
China is currently facing many serious environmental problems such as air and water pollution, the negative side effects of its rapid economic growth. Especially, water pollution becames worse and worse in lakes (the Taihu Lake, the Chaohu Lake, the Dianchi Lake), rivers in northeastern and northern China which is short of water resources (the Liaohe River, the Haihe River), and rivers with small gradient (the Huaihe River).
Water quality is particularly poor in the Huaihe River Basin, a rapid economic developing region in China. With a total area of 270,000 square meters, there are 165 million (2000) people living in the basin. The population density is 4.8 times higher than the national average. Based on the results of water quality measured several years ago, it was found that the Huaihe River was the most polluted one among China’s seven largest rivers.
A total of 11,000 dams and other flood control facilities like diversion weirs and floodgates have been built by 2000 to protect flat, low lands along the river from flood disaster and make social and economic development possible in the region. These facilities do perform functions of flood control and water resources development properly. However, the wrong operations also raised serious effects on the region’s water environment in the last decades.
For example, when a heavy flood struck the region in July 1994, discharge of water from dams brought pollutants in sediment of river channel downstream. It became one of notorious incidents of water pollution in China, which not only impacted water quality and the eco-system in the region, but also caused serious health problems for many local residents.
Japan has had the similar environmental problems caused by local industries in a fast-growing economy. Such problems are likely to occur in regions along many rivers in China such as the Huaihe River and in other developing countries of Asia. However, lessons from Japan’s experiences cannot be applied automatically to other Asian countries with the acceleration of economic globalization. Since pollution due to economic development began from decades ago in Japan which was more earlier than other Asian nations when these countries started experiencing the same problem. As a result Japanese and Chinese researchers are working together to study the problem of deteriorating water quality in the Huaihe Basin.
This joint study between Japanese and Chinese researchers tried to figure out ways to solve the problems of deteriorating water quality in the Huaihe Basin and the following issues are focused.
a) What kind of measures should be taken to identify the causes of water pollution in the region?
b) What kind of effects of water utilization structures have on the local eco-system and environment?
c) How the water-utilization structures should be operated to ensure the repair of the damaged eco-system and improvement in water quality?
At first, the study listed the problems of the Huaihe Basin and the pollution reasons were found out. Then issues related to necessary technologies and environmental restoration were discussed and the recommendations measurement for sustainable water management were made.
Main Achievements:
1) Management of effluences with an environmental impact of water utilization structures was designed to protect the eco-system and water environment in the Huaihe Basin.
2) Development of a GIS-based water environment management model was built to research the water quality and eco-systems at the typical sites in the Huaihe Basin.
3) Demonstration of the possibility of effective water resources management and eco-system preservation was made in the special part of the river of the Huaihe Basin.
Impression of this program:
This program enabled me to take part in the joint research when I studied the Japan’s state-of-the-art technologies related to water environment under the guidance of Professor Tang Changyuan who are in the Faculty of Horticulture, Chiba University.
Of these years it is the first time for me to engage in academic research on Japanese culture and environment for an extended period of time. Prof. Tang’s lab which has made many achievements attracts many talented students. It is very popular not only in Chiba University but also in the whole Japanese academic community. I would like to take this opportunity to express my great gratitude to Prof. Tang and other teachers and I also would like to thank administrative staff members of Chiba University who kindly supported my research. My gratitude also goes to JASSO, which is a very good system. I hope it will grow and expand in future.
<Study in Japan>
After graduating from Heibei College of Geology, where I studied with the major of hydrogeology and applied geology, I was employed by Jiaozuo Mining Institute. Soon after, I entered Changchun College of Geology and obtained the master’s degree in hydrogeology field there. Then, I engaged mainly in education and research related to mine flood prevention. At that time I was also thinking about boarding my research field to become a better-qualified researcher. During that time, Prof. Sun, one of my senior colleagues, came back to China after studying in Japan for two and a half years. Thanks to the recommendation of Prof. Sun’s and Prof. Isamu Kayane at the University of Tsukuba, an internationally famous expert in hydrogeology, I was allowed to go to Japan and study in the University of Tsukuba as a Japanese government (Monbukagakusho: MEXT) scholarship student.
Memories and Impression about Japan
Initially, I was a little nervous because it was my first overseas trip and even my first flight. However, there was scarcely trouble when I landed in Narita airport and arrived in Japan. I was picked up at the airport by Maki Tsujimura, a senior researcher at the same lab and currently an associate professor at the University of Tsukuba, and Mr. Liu, currently professor at the China Academy of Meteorological Sciences.
We went to the Tsukuba Science City by taxi and railway. I couldn’t see the landscape since it was night. The two senior researchers made me feel relaxed because of their kindness.
I started my studying life at the university at the following day. I spent most of my time at the experiment room, the lab and my dormitory room while enjoying a good natural environment and good human relationships.
Under the guidance of my supervisor, I chose underground water and water cycle in Sri Lanka as the topic for my research.
While learning about new approaches and technologies of the research, I made overseas trips and attended several academic conferences. During the time of the four years of research at the university, I experienced both frustrating failures and exciting successes before obtaining a Doctor of Science degree. I really enjoyed my life of research in Japan. Here I would like to thank my excellent instructors, great senior researchers and kindly juniors.
Cooperation with Japan after Returning to My Country
When I came back to China I got a job at the Institute of Geographic Sciences and Natural Resources Research of the Chinese Academy of Sciences, the leading institute for water research in China. I have been involved in academic exchanges between Japanese and Chinese universities and research institutions in the areas of water cycle and water environment, including the University of Tsukuba, Chiba University, Aichi University, Kumamoto University, the National Institute for Environmental Studies, and the National Research Institute for Earth Science and Disaster Prevention and Hiroshima University. I visit Japan three times a year on average for international conferences, academic exchanges and other occasions.
