Landscape As The Representation Of Existence And New Tool For Sustainability Management

Nowadays, the ecological and environmental problems have become increasingly prominent in the context of global urbanization, but population is growing inevitably, and urban areas will continue to expand rapidly. The ability of human to influence world has been unprecedented increase, urbanization and modern civilization broke through geographical boundaries and political, culture differences, across the whole world. Unlike a simple function transformed of land in the past, today the process of urbanization is much more complex, purely natural or rural areas no longer exit, what behind them is always human needs and support. So contradictions between development and protection are universal, more than urban areas. Whether it is urban, rural or nature, required to coordinate the relationship between humans and nature, in order to achieve a sustainable future. Sustainable development is essentially a multidimensional, holistic concept. This means that it needs to cross over the gap between human and natural science, to seed a holistic and cooperation approach,it only can be achieved through an integration in truly sense.In this context landscape science re-gained in importance and development because of its inherent comprehensive and holistic characteristic, and a paradigm shift in Europe has been achieved, transformed from abstract theory to specific methods, actions and policies, becoming the core of sustainable development, nature conservation and land management at each scale in various countries. But in china "landscape" concept is extremely vague, the logical link between landscape and sustainability has not been established. The theory and method system of "Landscape science" is still relatively empty. Also in china the contradiction between ecological environment and economic growth increasingly intense and explicit, the demand for a new holistic approach is more urgent. China has its own inherent uniqueness, if there is no theoretical basis and lack of forward-looking, foreign experiences and methods cannot solve the fundamental problem, also difficult to promote the development and change of the entire planning and management system.Thus the purpose of this dissertation is to clarify the concept of landscape and establish the inherent correspondence with sustainability based on the research of history and basic theory, and with the help of phenomenology, classification and linguistics research methods, to analysis the logic chain and overall framework of landscape theories transformed to landscape actions, explore new methods and tools to manage landscape change to achieve sustainable development.The dissertation is mainly divided into three parts:The first part is the history and theory study,focuses on the history and paradigm shift of the concept of landscape.By analyzing the whole evolution process of"landscape/景观",to obtain a clear and unity meaning,to establish a clear relationship between the signifier and signified of"景观"as a scientific symbol.And make an indepth interpretation of the Convention which marks landscape transition from theory to practices.The second part is the theory construction research. Evolution of the concept landscape essentially reflects a new level of relationship between man and nature, environment, space both implies a binary opposition of thought, but landscape as a result of the interaction between human and nature, is intrinsically integrated, holistic, geographic entity and visibility, characteristic of a subjective and objective interaction totality. Based on phenomenology, and systems science, provides a theoretical basis and research methods to cognitive the integrated/holistic landscape world, especially the development of remote sensing images,as a mirror of reality landscape. And proposed that landscape as the representation and new tool for sustainability management. The nature of landscape management is to manage the impact of landscape character change. So based on classification and linguistic approach, can establish an overall theoretical framework and logic chain with the core of landscape character, form the landscape information and knowledge(landscape character assessment) to approaches and actions(landscape governance and decision-making).The third part is empirical research. Summarizes international experiences of LCA approaches, from transnational scale(Europe), national, regional to local scales, make a comparative analysis and summarized the latest technology, methods and characteristics. It also proved universal landscape approach. Finally take the Pearl River Delta as the research object, verify that landscape change as representation of urbanization process. And based on the theories and methods of holistic,analysis the current predicament of planning and management system in PRD or china,and make a preliminary attempt to construct a Landscape Planning and Management System in PRD, including landscape character classification, define landscape objectives and construct landscape governance framework, proposed practical advice for the reform of urban and country planning system.
