公路对自然资源的破坏和对自然环境的影响范围在路线两侧200 m～300 m左右,但对自然生态的影响要远远大于这一范围,美国哈佛大学地貌生态学家理查德·福曼认为,占地面积1%的公路,可以对20%国土的自然生态造成直接影响。公路的生态学效应公路的廊道与分割效应公路的廊道效应是由其结构特征所决定的。公路工程特别是高等级公路和公路网的建设 The destruction of natural resources by the highway and its impact on the natural environment range from about 200 m to 300 m on both sides of the route, but the impact on the natural ecology is much larger than this range. Richard Fu, a landscape ecologist at Harvard University in the United States, Mann claims that a 1% -owned road could have a direct impact on the natural habitat of 20% of the country. Ecological Effects of Roads Corridors and Segmentation of Roads Corridor effects of roads are determined by their structural characteristics. Highway engineering, especially high-grade highways and road network construction
