Theory Analysis And Design Scheme Of The Ecological Restoration Of Slopes

In this paper,we studied the ecological restorations of slopes in two programprojects,one is Wu-Shen High grade road,the other is the gangue dump of Mei fang coal mining area in Wuhai,Inner Mongolia.According to the natural environment,geological conditions and the characteristics of the two projects in the area of the two projects,the appropriate measures for vegetation restoration are carried out respectively.The results showed that the vegetation restoration of the two projects was in good condition,and achieved the expected goal.According to the results of this study,the main conclusions are as follows:(1)According to the results of Vegetation survey and vegetation adaptability evaluation of Wu-Shen high grade road,9 shrub plants,4 herbaceous plants and 3 vines are found to be better slope protection plants,and 4 vine plants are found to be good ecological plants.(2)it was found that the tensile strength and diameter of the plant roots basically met the logarithmic curve through the tensile test of the typical plant root of the Wu-Shen high grade road,and the tensile strength of Joe,irrigation,grass and Fujimoto Uene was close,and the average tensile strength of the root system was the largest,and the average tensile strength of the shrub root system was the smallest.The basic ordination was:herbs(48.7 N/mm~2)>lianas(42.8 N/mm~2)>arbors(42.7 N/mm~2)>shrubs(39.4 N/mm~2).(3)according to the basic situation of the Wu Shengao grade highway slope and the results of the investigation of vegetation adaptability,a targeted slope ecological restoration scheme has been formulated and carried out.(4)through the comparison of the high grade highway project of Wu Shen and the ecological restoration project of the coal gangue dump in the mine area of Wuhai,Inner Mongolia,the understanding of the ecological restoration of the slope is deepened.
