Design And Evaluation Of The Forest Belt Of Highway Ecological Landscape

With the rapid growth of China's economy,the highway has become an indispensable transportation infrastructure in modern life.The expressway ecological landscape is an important part of modern highway construction,which can protect and transform the weak ecological environment caused by the engineering construction.Under the premise of meeting the traffic functional requirements,combining the theoretical knowledge of ecology and landscape aesthetics,the highway environment with ecological value,landscape value and social value can be provided for the highway according to local conditions.This paper focuses on the design of Expressway ecological landscape forest belt and the evaluation of landscape benefit.First of all,starting from the current situation of domestic and foreign highway research,analysis of relevant theoretical knowledge,establish the theoretical framework of this paper.Secondly,this paper expounds the related concepts and characteristics of expressway,analyzes the design direction and design content of ecological landscape forest,and establishes the framework of this study.Finally,taking the design of the ecological landscape forest belt in Zengcheng section of Guangzhou expressway as an example,according to the design principle of the ecological landscape forest belt,the design of the expressway ecological landscape forest belt with south of the Five Ridges characteristics is discussed.The description method for the factor evaluation method,according to the particularity of the formation of highway landscape and its requirements to increase from the high ecological landscape forest as the research object,with some influence on the choice of landscape effect of indicators,the establishment of landscape evaluation system,evaluation of ecological landscape forest landscape from the high speed increasing effect.The research results are summarized as follows:(1)the ecological benefit,social benefit and economic benefit of the ecological landscape forest belt were analyzed,and the design principle was put forward.(2)systematically analyze the design content,design principle,design key points of the ecological landscape forest belt of Expressway and the ecological landscape forest soil plants in Guangdong.(3)through the landscape design and plant configuration to command the overall situation,guide the design,restore the ecological landscape broken by the construction of the highway.(4)establish the highway landscape evaluation method of descriptive factor method,establish evaluation system,evaluate and analyze the landscape effect of high speed ecological landscape forest,and put forward suggestions for improvement.
