随着社会经济的快速发展,道路网络已经成为当今社会和经济发展的中枢,其分布范围之广和发展速度之快,是其它建设工程都不可比拟的。道路的建设和扩展为社会发展提供保障、为人民生活提供方便的同时,也直接或间接影响生态系统的结构和功能。此外,道路的生态学影响具有扩散的特征,其影响面积超过道路本身面积的数十倍并且道路建设所带来的干扰是长期和不可逆的。本文利用Arcgis软件及遥感图像,通过对表示道路网络干扰强度的RV (Roadless Volume)指数的分析计算,以东营市为例,对不同道路影响等级下研究区内各土地利用类型的影响进行对比分析。分析研究的内容包括研究区内水域、滩涂、盐碱地、湿地、草地等生态用地以及耕地和建设用地七大土地利用类型。结果表明:不同道路影响等级下滩涂、湿地的面积随等级的增加而减少,其中从一级到二级下降的幅度最大;草地、水域和盐碱地的面积随影响等级的升高总体呈下降趋势且降幅十分明显;耕地的面积从总体来看也呈减少趋势但幅度相比以上生态用地而言并不十分强烈;建设用地的面积随道路影响等级的增加有上升趋势。通过以上分析结果说明道路网络的不断扩展对区域土地利用的影响显著,其中对生态用地的干扰尤为明显。

With the rapid development of social economy, the road network has become the most social and economic development of the central and the distribution broad scope and developing fast, is other construction project is incomparable. Building of roads and expanded to provide security, social development for people's life, but also provide convenient directly or indirectly affect the structure and function of ecological system. 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.
