Two Lakes Plain Wetland System Stability Assessment And Ecological Restoration Design

The study of the theory of degeneration ecosystem restoration and practice is the chief focus of ecology, geography and regional sciences. The typical region and type of degeneration ecosystem were probed to approach theoretic relevant research practice implications. Ecosystem of wetland had the richest bio-diversity of nature and had the highest ecological function, which had the important environmental function and benefit. At present, ecosystems of wetland were regarded as one of the most fragile ecosystems on the earth. It degenerated in different degree, which influenced the protection and the use of wetland resources under the natural disturbance and artificial disturbance. Resuming good structure and function of degeneration ecosystem and rebuilding degeneration ecosystem were important to wetland protection and regional sustainable development.This paper combines with the project of national ecology protection-ecosystem restoration of protection region in Honghu Lake wetland and South Dongting Lake Wetland, and selects the wetland ecosystem of Jiang-nan and Dongting Plain as research objection. The research achievement of forefathers summarized, 3S technology used, the method of linking selected spots with the entire area used, the theory of ecology resume, the ecological stability of wetland, the situation that the ecology degeneration and countermeasure of restoration, had been discussed. And ecology resume was designed on typical wetland, in order to guide the practice, which was carried of ecology resumes of wetland of the plain of Jiang-han and Dongting Plain.There are three parts in the paper:The content in the first part is theoretical research, which includes the preface, chapter one and chapter two. Firstly, the meaning of the title, research method, technological route and the range of studying area had been recommended and defined briefly. Secondly, the research of ecology restoration was summarized in this article, and the concepts of ecology resume and ecology were put up. The newest progress of domestic and international research of ecology resume was summed up. The development and research tendency of the ecology resume in future were proposed. And the study of the progress of ecology resumes of wetland was expanded. Then, theoretical foundation of ecology resume was discussed. Theory of evolvement of the ecosystem is the foundation of epistemology, and sustainable development theory is the foundation of direction theory, and management theory of ecological system is the foundation of Methodology. The ecology resume was a kind of research and practice of ecology of the above-mentioned three major theories. In this paper, the goal of the ecology resume, technology of the ecology resume and theory of the ecology resume were given a preliminary discussed. And the characteristic of ecosystem of wetland had been described at the same time. This part had established the theoretical foundation and methodology guidance for research and practice of the ecology resumeof Jiang-han and Dongting Plain.The content of the second part is the analysis of survey and the study of the ecology degradation in Jiang-han and Dongting Plain using RS technology, which includes chapter three and chapter four. History of evolution and development of the wetland of Jiang-han and Dongting Plain was introduced at first. The wetland, since 1980s, was monitored there, using TM image of the three periods of 1986, 1996, and 2000. It was thought that there were various of wetlands in the plain of Jiang-han and Dongting Plain, the distribution is centralized, the reduce speed of the area of natural wetland in the plain become low, but the area was still reducing. Secondly, in the article, the ecology the character of ecology degradation of wetland in Jiang-han and Dongting Plain is discussed. Situation that the ecology of Honghu and South DongTing Lake wetland degenerated is given a special analysis. The degradation of wetland in plain of Jiang-han and Dongting Plain, displayed mainly in wither of the wetland, water...
