| "The history of human civilization development is the history of relations between human beings and nature." In recent years, the frequent occurrence of environmental pollution problems, resource scarcity and ecosystem degradation are becoming more and more serious, which makes people be aware of the importance and urgency of ecological environmental protection more profoundly. So the construction of ecological civilization has been put forward. In the face of the specific environmental problems, ecological restoration has become a very important approach for preventing natural or man-made ecological destruction, improving the ecological environment and protecting the earth. Ecological restoration is based on the relationship between the ecosystem and the environment, including a series of measures from macro to micro, and having characteristics of multidisciplinary cross in both theory research and practical application. It not only embodies the idea of the harmony between human beings and nature but also expresses correct understanding of the nature that we need to advocate. As to improving the effect of ecological restoration and achieving the goal of ecological restoration, it needs technological strategies not only aiming at actual environmental problems but also considering the comprehensive benefit of society, economy, culture and environment. It highlights the increasingly important role of innovating precaution ideas and management approaches synchronously. Moreover, it is a combination of effective measures that can solve ecological problems, improve the quality of environment, and finally achieve the sustainable development of resource and economic.This study briefly introduced the historical evolution of Xiamen Yundang Lagoon and also briefly showed the effect of comprehensive improvement there, then point out the existing ecological environment problems which remain serious. So this study takes ecological restoration in Yundang Lagoon as the object of study and it is conducted basing on collecting available material related to the causes of existing problems and improvement approaches with the combination of the results for experimentation in the lab. Furthermore, this study put forward the basic thoughts and technological strategies for ecological restoration in Yundang Lagoon. The basic thoughts emphasizes the fundamental role of the comprehensive improvement, especially attach importance to dredging and pollution control. As water quality and sediment conditions in Yundang Lagoon has preliminarily improved, the bioremediation measures of technological strategies for ecological restoration in Yundang Lagoon can be carried out. These technological strategies include four main technological measures:the mangrove wetland construction, the ecological floating bed technology, the macroalgae restoration technology, and food chains reconstruction. In addition, each process of technological strategies needs to be ecologically monitored and modified if necessary in a regular basis.This thesis consists of6chapters and the main contents include the related concepts of ecological restoration, research progress in related field, historical evolution of Yundang Lagoon and its present situation of the pollution, basic thoughts of ecological restoration and the technological strategies for ecological restoration in Yundang Lagoon, as well as the implementing and guarantee of ecological restoration technological strategies in Yundang Lagoon. The thesis not only demonstrates the feasibility and rationality of the technological strategies, but also illustrates the advantage of these strategies, discusses the relationship among the steps of the technology strategies and gives suggestions on how to implement the technological strategies with both technology and management methods. Hope this study can make contributions to improving the benefit of society, economy, culture and environment, then provide the reference of solving analogous problems as well. |
