I would like to take this opportunity to express my gratitude to the following people: First and foremost, I would like to express my sincere gratitude to Prof. Dr. Bernd Hansjürgens for his supervision and guidance. With his kind help, I received the precious chance to do my Ph.D. study in UFZ. Also I have been receiving his continuous support during the entire time of my research stay. He provided lots of thorough and constructive suggestions on my dissertation. Secondly, I would like to thank Prof. Dr. -Ing. Rober Holländer for his willingness to supervise me, and his continuous support so that I can deliver my thesis at the University of Leipzig. Thirdly, I am heartily thankful to Dr. Nele Lienhoop, who helped me a lot in completing the writing of this dissertation. She was always there to meet and talk about my ideas and to ask me good questions to help me. Furthermore, there are lots of other people who I would like to thank: Sara Herkle provided the survey data collected in Leipzig and Halle, Germany. Without these data, my thesis could not have been completed. It is my great honor to thank Prof. John B. Loomis (Department of Agriculture and Resources Economics, Colorado State University), who was always very patient to answer my questions and offered very good suggestions on the CVM study. I would like to thank those who provided valuable information and advice on conservation project of YFPs, including Secretary-General Prof. Nianhua Dai (Jiangxi Academy of Science, Ecological Society of Jiangxi Province, Nanchang, China), Prof. Ding Wang (Institute of Hydrobiology, Chinese Academy of Science, Wuhan, China), Associate Prof. Kexiong Wang (Institute of Hydrobiology, Chinese Academy of Science, Wuhan, China), Dr. Xiujiang Zhao (Institute of Hydrobiology, Chinese Academy of Science, Wuhan, China), Shuyuan Wu (Section chief of Resources and Environmental Protection, Jiangxi Administration of Fishery Bureau, Nanchang, China). I offer my regards and blessings to all of those who supported me in any respect during the completion of the thesis, including Dr. Katharine N. Farrell (who gives me encouragement and con fi dence sustaining me overcome all the dif fi culties, helps me v vi Acknowledgments in proof-reading several chapters and statistics), Alexia Peterson (my International- Cultural Communication teacher, who taught me how to deal with business in a completely different cultural background. Her kind assistance made my life more comfortable and easier), Dr. Paul Lehmann (my of fi ce mate, who never hesitated to offer his kind help) and Aaron Leopold (my of fi ce mate, who helped me a lot with my English). It is also a great opportunity to show my great gratitude to three secretaries, Helga Dietsch, Monika Nussbaum, and Birgit Stumvoll who helped me a great deal with administrative matters and a pleasure to thank all the colleagues in Department ÖKUS and Chinese colleagues at the UFZ, who helped broaden my view and knowledge, and made lots of fun in my life. It is my great honor to meet and get to know you all in Leipzig. Besides, I would like to thank the Helmholtz Center for Environmental Research- UFZ for providing a good environment and facilities to complete this project. The UFZ also fi nanced my fi eld trip to China. Also, I would like to take this opportunity to thank to the Junior Scientist Exchange Program between the China Scholarship Council (CSC) and the Helmholtz Association of German Research Centers for offering the fi nancial support. Finally, I am indebted to my lovely family: my parents, Hongmei Liu and Ruihe Dong, for giving me life in the fi rst place, for educating me with aspects from both arts and sciences, for educating me how to be a useful person, for unconditional support and encouragement to pursue my interests, even when interests went beyond boundaries of language, fi eld, and geography. My brother, Gang Dong and his wife, Yuanyuan Wang, for listening to my complaints and frustrations, and for believing in me, and for kind help in my life and work.
