The Ecological Damage And Restoration Technology Research Of The Jiangyan Highway Construction

As an important national infrastructure, highway becomes the main chunnel that contacts the city with city, or city with country. The production and development of highway changes the macro-traffic patterns of the world, and effectively promotes the social economic development of all the countries of the world. The rapid developed highway, promotes the economic development in the region while taking the greater pressure on the ecological environment. Highway construction activities make a negative impact on the ecosystem of along the way, and the natural landscape and the ecological environment were seriously damaged.The highway construction of ecological damage analysis and restoration technology study that crosses over the highway engineer, ecology, plant physiology, aesthetics, garden landscape and other aspects of comprehensive scientific knowledge, is a multi-disciplinary intergrated domain, and it is also a new science and technology realm at present. Its meaning lies on that it analyzes the significant impact and destroy intension of ecological environment of along the highway construction project, and predicts the ecological characteristics, in order to adopt what homologous improvement to reduce the negative of highway construction process, to minimize the harm. Therefore, the analysis of ecological damage to the highway construction and restoration technology has a great signigicance on reducing environment damage, protecting the original ecological resources and natural landscape, and improving the highway design concepts. Some countries such as America, Australia, Canada, Sweden, Germany and other countries have studied the ecological damage to highway and restoration techniques for a long time, and have obtained some productions. In our country, the influence appraisal of the highway construction starts late. In the early days people didn't attach importance to the highway construction of ecological damage analysis and restoration technology.Along with the continuously improved life level, people's request for the ecological protection also will becomes more and more higher. At the same time, the strongly comprehensive ecological damage problem is a dynamic state space of interaction zoology genes. The research wants to resolve the inconsistency between the great development of the highway and the slow development of the highway construction of ecological damage, and it is first to build up the ecological damage evaluation system of highway construction, then carry on the in-depth study and research, and advance the corresponding measures for the ecological restoration. This is a guide to the highway ecological protection and ecological restoration work of great important and necessary.The paper takes attention on the highway ecological damage analysis and ecological restoration techniques, and studies on the analysis of the ecological damage and restoration techniques problems. It is based on full investigation on national and international methods for the analysis of highway ecological damage, and studies the main evaluation method and the highway ecological damage index system with the foundation of existing data. The principle is comprehensive, representative, feasible, typical, scientific, perspicuous and maneuverable. Consulting the index systems of highway environment influence evaluation, the ecosystem environment influence evaluation and various ecosystem landscape, it uses the brains storm method, investigation method, target descomposition method, Delphi method etc. to set up a complete highway construction ecological damage analysis index system with complete of many layers and independence, namely the biological factors– environment factors– social factors of the index system, and uses the AHP method to ascertain the important degree of each index.Based on the highway construction ecological damage indexes, the paper consults the relevant investigation on national and international, and studies the theories of these indexes. Under detailed analysis onthe meaning of these indexes, it uses these theories to quantify these factors with right analysis methods and qualitative analysis of which can not be quantifiable factors. Through the actual target, these ecological damage factores of the Jiangyan Highway are analyed the damage factores of the highway construction ecological damage.are educed in the paper.According to the evaluation method of the national and international related field, it chooses the faint-synthesis evaluation method to evaluate the whole Jiangyan Highway ecological damage in the paper. According to the biological factors– environment factors– social factors index analysis system, on the basis of factors, the paper analyzes and evaluates the ecological damage of Jianghuang part and Dunyan part of the Jiangyan Highway, and gets the evaluation data of the ecological damage. The results show that the highway construction ecological damage evaluation index system established in the thesis can reflect the difference of the highway ecological damage in a specific way, and can reflect the difference degree. The index system could reflect the actual circumstance and have the good referenced value to the research work of the aftertime.According to analysis of the extent of ecological damage, the paper consults the ecological restoration technique of the national and international, advances the different measures on ecological restoration to different types ecological damage, and tests the tracking research entities relying on the Jiangyan highway ecological restoration experiments. Then it preliminarily analyzes the effect of ecological restoration experiments, to further test the measures taken to restore the ecological scientific and reasonable.The thesis provides the foundation for the highway construction ecological damage analysis and restoration. The theories of the index system and the method of the evaluation provide the beneficial reference to the highway ecological factors analysis, and also to the highway ecological restoration and its effect analysis.The exittent problems in the thesis need to be developed further and deeply, and will be examined continuously in practice work.
