| Because our country is a developing country, the number of population in city is more and more big, the ecological environment is relatively fragile, coupled with a relative lack of funds and technology, urban problem is particularly prominent. The urbanization process in China is facing a pressure are: the lack of an increasing population, the resources is more and more serious, and the mounting of environmental load. Therefore, the protection and construction of urban ecological environment, to create more good urban survival and development conditions become the top priority today. Landscape functional comprehensive assessment of city and community building model were studied with ecological, economic, social, cultural, aesthetic value and practical significance, and due to the existing research, it is likely for study on ecological significance, we could enter, ecological urban landscape construction, community building pattern, the condition of economic development together four aspects to carry on the comprehensive evaluation, the existing research has the certain breakthrough. At the same time, the existing research there is no specific points out that the influence factors of city landscape architecture in the degree of influence on urban landscape, and the analytic hierarchy process can be based on the evaluation index calculation to determine the impact on the overall goal of the most important factor, this method is more objective comprehensive consideration of all the indicators, to avoid the only rule of thumb to determine the index weight of error and makes the evaluation more scientific and reasonable. Based on this, we select in Baotou and Hohhot city as the research object, using the analytic hierarchy process (AHP) to study the influence of two factors to evaluate urban landscape features, find out the most important influence factors, analysis and evaluation on the two cities respectively. Research results show that we should attach great importance to the study of landscape system comprehensive function, improve the urban landscape construction as soon as possible, is one of the important guarantee for the sustainable development of city, and aims at the problems existing in the modern city landscape is put forward the following policy recommendations:scientific understanding the features and functions of greening plants, the disadvantages, made in the application of species diversity; Adhere to the local characteristics, reflect the historical context; Optimize the structure of urban landscape layout; People-oriented, scientific planning and design; Strengthen the propaganda, raise awareness of greening. |
