The Research On The Evaluation Method Of The Urban Landscape Elements

At the same time, High-speed city build is becoming a driving force for urbanization. Rapid urbanization and economic growth, the population agglomeration restricts the development of urban; ecology, environment, the needs of material and cultural, and the problem of sustainable development make the urban develop slower and slower. A lot of urban landscape only stays in the shallow understanding level, which lacks of systematic grasp about urban landscape, and the consciousness of integrity control. So it is very urgent to set up scientific theory about the landscape system which relies on the system evaluation.Urban landscape is a subsystem of city system. Its formation and development has its complexity. The good design of the urban landscape can not be done in practice. So the planning and design is not implemented in practice frequently. The urban landscape system optimization approach which based on the single landscape subject areas could be under restrictions. The research object of the systems engineering is complex system. Therefore, in this paper, we study the urban landscape which combining with the optimization theory and method of system engineering. The evaluation factors of landscape system solve the problem about the direction of urban development and construction planning. It can make the quantitative analysis of the landscape system elements. Further, it can make the reasonable evaluation of landscape system factors.This paper mainly studies on the evaluation method of the urban landscape elements which based on the optimization theory about the system elements. We use the theory such as the system engineering, system optimization to in-depth study the optimization theory about the system elements. And on this basis we use the analytic hierarchy process (ahp), the evaluation method of the fuzzy comprehensive, the evaluation method of questionnaire to research on the evaluation method of the urban landscape system elements. Through relevant theory and method in combination, we take the city of Zhaodong for example which is familiar to the author to make research and analysis. By summing up the results of the survey, we make the evaluation of the representative elements which is related to the protruding problem. Through the theory of optimization, we make the feasibility evaluation of the landscape elements. So we provide the reference for building high quality of systematic urban landscape. And it is the foundation for further research on the landscape.
