Study On The Dynamic Evaluation Of The Development Level Of Urban Landscaping

The evaluation and analysis of the level of urban greening is helpful to understand the development of landscape greening,The measures taken to improve the effectiveness of landscaping construction,to facilitate more targeted adjustment program,can be used as the future development of China's urban landscape development policy to provide a scientific basis.In this paper,a new dynamic evaluation method is established by using entropy weight method and TOPSIS method,to get science in western regions from 2008-2015 years of landscape development status and trends of visually,finally get the greening development dynamic evaluation of the value of the city.The main results are as follows:(1)In 2008-2015 years,the level of development of landscape greening status significantly increased of Inner Mongolia and Chongqing,meanwhile the state of development in Guangxi ranking has declined.As for Shanxi and Gansu,the level of development of landscape has a small amplitude fluctuation,as for Sichuan,Guizhou,Yunnan,Xinjiang,Tibet,Qinghai and Ningxia,the level of development of the landscape level were stable.(2)In 2008-2015 years,The development trend of the landscape level in Guangxi showed a trend of growth,and then decreased.The level of landscape greening in Chongqing showed a slight fluctuation,and the trend of sustainable growth was estimated;the landscape greening level of development trend of increaseand decrease have a bigger fluctuation for Inner Mongolia,Guizhou,Xinjiang,Gansu,Ningxia,Shaanxi,Yunnan,Qinghai,Tibet and Sichuan.(3)The results of the dynamic evaluation of the development level of the urban landscaping in 12 provinces and cities in the western region of 2008-2015 years from strong to weak: Sichuan,Yunnan,Chongqing,Inner Mongolia,Shaanxi,Xinjiang,Gansu,Guizhou,Ningxia,Qinghai,Tibet.Finally through gray correlation and cluster analysis verify the feasibility and scientific of the dynamic comprehensive evaluation method.
