The Study On The Pre-evaluation Method For Highway Landscape Design

With the notion of sustainable development has gone deep into the people's mind,the people have already been aware of the road not only would has the transportation function,but also the esthetics function of road would be consider from many point of view,such as landscape,environment,etc.Nowadays,the designs and pre-evaluations of the highway landscape have already become a new question;therefore,it has significant theoretic and practical value to research on the indicator set of the road landscape.The thesis take attention on the highway landscape evaluation in medium, studies on some theories of the landscape.The thesis is based on full investigation national and international methods of the highway landscape and studies the main pre-evaluation method and the landscape evaluation index system with the foundation of existing data.The principle is comprehensive,science,independent, combining with quantitative method and qualitative method,perspicuity and maneuverability.The thesis uses the AHP method to make sure the important degree of each index.The thesis according to the evaluation method of the national and international related field and choose the fuzzy-synthesis evaluation method to evaluate the highway landscape.This method is combined qualitative and quantitative method together,being applicable to the synthesis problem such as the highway landscape evaluation.The step include:confirm purpose;certain index system of evaluation; build up step-up layers;constitute.judgment matrix;arrange layers and consistency examinations;arrange chief layers and consistency examinations.The index system could completely and directly reflect the problem of the highway landscape.While carrying on a special research should combine the different cities,different districts to choose the index and ensure the important degree of the index.The thesis chooses on highways that have the representative highway to carry on the example pre-evaluation,difference for grow the Suiyue middle highway.Make sure the concrete index system and pre-evaluate with the faint-synthesis method.The index system the thesis set up could reflect the actual circumstance and have the good reference value to the research work of the aftertime. Appling the faint--synthesis evaluation method,its result can accurately and objectively reflect the actual circumstance of the highway,the method,which is brief and easy,have the practicability and can reflect the weak aspects.It could provide the basis to set up the road segment for improving the measure and to construct the road segment for the design,construction,management,maintain etc.The works all have the profound meaning.
