摘要

Plant diversity evaluation of highway construction of nature reserve is one important task in a construction project. I analyze and appraisal the plant diversity problems caused by the rebuilding and extension project of No.209 national highway Duchuan to Chunshuya section from plant species diversity, plant composition characteristics, vegetation type's diversity and national rare and endangered plants in the construction region. The highway reconstruction through the Savage Valley Nature Reserve basically causes no destructive effects on plant diversity, but there are still somernnegative effects. In this paper , I put forward scientific, reasonable and feasiblernmeasures and methods to the plant diversity protection by combining with the natural environment characteristics of the highway construction region.
