With a doctorate in eco-environmental engineering, I entered in IWHR in 2010 and now I have been working in the strategic planning department of the hydropower center for 8 years. My main research areas include watershed ecosystem services, sustainable hydropower development, ecological environmental impact of hydropower development, etc.

Research on key technologies and applications of alternative habitats protection in tributary

In China, the Jinsha River basin is significant in future hydropower development with its rich water resources. These years, more and more scholars have increasingly focused on the research of alternative habitats protection in tributary in order to mitigate the adverse effects on ecological environment caused by hydropower development. Guided by multidisciplinary theories and methods such as ecology, environmental science, hydraulics, economics, and similar systems theory, we created a set of evaluation systems and technical methods to quantitatively research the feasibility and suitability for the Chishui River as an alternative habitat in tributary of the Jinsha River, targeting on the protection of economical suitability for Chishui River. In the feasibility analysis stage, several alternative habitats protection tributaries were initially selected, based on the habitat requirements of the target fish. Then during the suitability stage, the optimum from all the schemes was selected. The results shows that the Chishui River is feasible and suitable as an alternative habitat for downstream of the Jinsha River. The ecological value of Chishui River habitat protection is 1.63 times the value of direct hydropower generation of the Jinsha River. We will learn more about the detail on the key technologies of river habitat protection and the evaluation of river habitat conservation effects in the future research. Through the feedback information of evaluation, the key technologies of river habitat protection are further improved, and the sustainable protection of alternative habitats in tributary are well realized.
