摘要: 高速公路水土流失损失是一个带状区域人为加速土壤侵蚀所产生的生态环境负效益。在综合考虑重庆绕城 高速公路建设项目基础上,系统讨论了高速公路的侵蚀地貌单元和沿线敏感区域,重点筛选出水土流失评价指标, 建立了指标与经济之间的关系,提出了计算水土流失经济损失的公式,及山区公路建设产生的土壤侵蚀治理和预 防的量化依据。
关键词: 高速公路, 水土流失, 经济损失, 侵蚀单元, 敏感区
Abstract: Economic loss of soil and water loss in highway has negative benefit by man - made accelerated erosion in zonal region. Making a comprehensive survey on outer round of Chongqing,the eroded units and the environmental sensitive area along the line are discussed. The paper choices the evaluation index of soil and water loss. The relation of the evaluation index and economic loss is set up. The result provides a quantificational reference to soil eroded treat and protection of highway construction in mountain.
Key words: highway, soil and water erosion, economic loss, the eroded units, sensitive area
