Analysis on Economic Loss of Soil and Water Eroded during Highway Construction in Mountain Area |
| |
| 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. |
