In addition, the ecological influence has spread road the characteristics, its influence over the road itself area of dozens of times and road construction is the interference caused by the long-term and irreversible. Using the Arcgis software and remote sensing image, based on road network interference intensity said Roadless Volume (RV) index calculation and analysis, for example, in dongying city of different road influence rank the area under the influence of various land use types were analyzed. Analysis the research contents of research in this area, including the saline-alkali flats, wetlands,, meadow ecosystem land and farmland and construction land seven types of land use. The results indicate that the different road influence rank flats, the area of wetland under decreased with level, including from level 1 to level 2 the magnitude of the drop is greatest; Grassland, water and saline-alkali land area with influence rank increases the overall decline in and fell very apparent; The area of cultivated land from overall also have slowed but range for ecological land than above is not very strong; Use the land for construction area increased influence rank with the road had a tendency to rise. Through the above analysis results show that the expansion of road network of regional land use, including the significant influence on ecological land of interference is especially remarkable.
