The Influence of Highway on the Roadside Landscape Pattern Change of Land Use

摘要: Based on the theory of landscape ecology, method integration remote sensing and geographical information system technology, example Beijing-Kaifeng Highway (Daxing section), dynamic change characteristics land use type along highway was discussed. The following content mainly analyzed: structure pattern buffer zone 1kilometers distance. results were as follows. Firstly, during 12 years from 1995 to 2007, there rather intense types in study area. number patches increased degree fragmentation strengthened, which demonstrated that road construction had brought convenient traffic, easier human activities, but also deeper advantageous has changed farmland land. Secondly, area occupied most From calculation, decreased with increase distance Highway. tended be stable 5kilometers. There more decrease when it closer highway. When between 0 5kilometers, However, just contrary over It showed influence range covered 5kilometers east west trend. Thirdly, calculation evenness index (SIEI) , diversity (SIDI), contagion (CONTAG) shape (LSI) stable. That is say, little ecological environment, heterogeneity diversity. 4 5 kilometers west, analyzed patch index, average index.
