Abstract:
Rational arrangement of the land use layout of the open pit slope is the key in the reclamation of open pit mine.Taking Shanxi Lu xin open pit as an example,according to the principle of "suitable for the species",this paper analyzes the original landscape environment of farmland,woodland,grassland on the altitude,soil depth,the terrain gradient,terrain slope to the site environment,constructs land use suitability evaluation index system to develop a reasonable land use pattern of the slope of the post platform.Results show that:① the main elevation of the area of cultivated land distribution height in 1240m-1380m,soil thickness in more than 100 cm,slope basic in less than 6 degrees;woodland is evenly distributed in the altitude,at 80cm soil layer thickness gradient below 25 degrees of platform and shady slope distribution is wide;grassland in the elevation height,thickness of soil layer,slope degree and slope to within the scope of the uniform distribution;② after the mine reclamation,cultivated land area is about 594.47hm
2,46.3% of the total mining area,barren land area is about 340.94hm
2,accounting for the total mining area of 26.56%,appropriate grassland area is about 348.45hm
2,accounted for 27.14% of the total mining area
