| Construction of the highway can accelerate economy of clime, but it will result in effect of environment and highway landscape ecology. Because landscape of highway is a complex system, so it is difficulty to analyze them completely. Nowadays, because there aren't many methods which can give us a comprehensive environment evaluation, so we must find new methods, technologies.This paper based on west science and technology project research reconstruction of highway landscape ecology. It is based on the evaluation gene which is according to the investigation and analyzed on the travel highway. Applying 3S technology to manager evaluate gene, it conceives a flat of GIS, applying public-opinion poll analytic hierarchy process and principal component analysis to travel highway landscape. Comparing three results of evaluation, acquire coherence between them, so it explains flexibility, reliability and veracity.The paper discusses 3S technologies in the field of highway landscape environment evaluation and environment data acquiring, data managing and evaluation. It expatiate the analytic hierarchy process and principal component analysis in the landscape evaluation in details. The main work and research results include:(1) Applying 3S technologies to select and manage of gene, based on flat of GIS, applying public-opinion poll to evaluate landscape environment(2) Applying analytic hierarchy process and principal component analysis in the landscape evaluation, it gives the validity of methods.Tourist high way landscape evaluation and visual effects are both new problems. And there aren't fixed modes and mature design methods and theories for them. This paper discusses the evaluation on road sight, which will make the evaluation and design for road sight more intuitionistic and more convenient. These methods may also be applied to the evaluation on road strategic environment and district environment, and every stage of road layout, construction, and management.
