Study On Ecological Entironment Impact Of The Highwayconstruction Related To Nature Reserve

With the rapid development of China’s transportation industry, more and more highway construction projects relates to nature reserve, due to the sensitivity of ecological environment of nature reserve, road construction will have a significant adverse impact, making the contradiction between the social and economic development and resource protection have become increasingly prominent. At the present stage, most researches which related to the eco-environmental impact of highway construction projects in nature reserve only give a qualitative elaboration of ecological impact, but the conclusion of ecological impact is not sufficiently clear. And ecological preventive measures are lack of pertinence, so these researches cannot well provide a reliable and reasonable scientific basis for the management departments of nature reserve.The highway construction projects related to nature reserve, both in the construction or operation, will generate direct or indirect adverse impact on the ecological environment of nature reserve. Depending on the types of nature reserves involved in the project, the extent of impact and characteristics will be different, the main impact on ecological environment should be species, ecosystems, soil erosion in these three areas to consider. Major impact on ecological environment should be considered from three aspects, which are species, ecosystems, soil erosion. The analysis of the ecological environmental impact of nature reserve should grasp the following several points:to identify the relevant circumstances of nature reserves, such as functional division, property, protection targets, the characteristics of ecological system, etc; to focus on the impact assessment of the vital ecosystems of nature reserve; to grasp the root of the nature reserve protection strategy and evaluate the impact scientifically; to propose targeted protection measures and emphasis on environmental protection measures during the construction.In the instance of the XU08line of Tangmai highway construction project, through the collection of large amounts of data and site survey, the ecological status of the project area was got a more detailed investigation. And the article has a comprehensive evaluation of the ecological status and ecological impacts under the application of analogy method, the quality index method, productivity evaluation method and the synthetic evaluation index method. And based on the ecological sensitivity of project area, the article proposes targeted ecological measures. In addition, the article has a study on the eco-environmental impact of highway construction projects related to nature reserve in detail, and puts forward some suggestions for the evaluation of ecological impact of highway construction projects related to nature reserve.
