Other Abstract

Abstract:Soil erosion in mining area is a major problem for the ecological security,especially in Loess Plateau.
Non-conservation managing practices have further aggravated the situation,especially in new dump
slope,which are affected by the highest rates of soil erosion among mining area.Therefore,it is necessary
to find a right managing model for the environment restoration of mining area.The one-year dump slopes
were selected to evaluate rill erosion.Two managing models were applied to these one-year slopes of opencast
coal mine in Inner Mongolia Erdos Yongli.Type A was Salix Psammophila Checkerboard mixed Astragalus
adsurgens and type B was Salix Psammophila Checkerboard.In order to easily test the effect of
A and B,a bare lope was regarded as a contrast(CK).The experiment included five sample sites:two A,
two B,and a CK.Results showed that:rill density,degree of rill dissection,and rill width-depth ratio
showed the trend of declining-rising-declining with increasing slope length on CK,but steadily rising on A,
rising-declining on B;The rill erosion amount of CK increased rapidly 8minterval,and reached 283.73
kg;the total rill erosion amount of A and B decreased 46.36%and 35.09%compared to CK.Therefore,
A type decreased rill erosion due to the function of Astragalus adsurgens;The accumulation of rill erosion
changed with the increase of slope length,and the relationships among them was exponential function ofCK,and power function of A and B;the effect of control rill erosion was not different between 75%coverage
and 45%coverage before 14m.The 75%coverage was more effective than 45% between 14~20m,
and the rill erosion amount decreased 53.32%~61.49%.However,the effective control on erosion was
within 20m.This study may provide some scientific basis for the management of dump slope and the ecological
security of mining area.
