Covering soil is crucial procedure for the coal gangue mountain repairing,which influences the soil nutrition element of gangue mountain.Besides,the environmental factors such as moisture content and temperature vary from different slope of gangue mountain,which lead the difference of nutrient element content and influences plant growing.In this paper,the effect of different proportion of covering soil on nutrient elements in coal gangue was studied.5 slopes surface of sunny,semi-sunny,shady,semi-shady and platforms on 280 gangue mountains in the Yangquan City of Shanxi Province were selected the nutrient elements in different soil condition studied.Results showed that the content of organic matter,total nitrogen,total phosphorus and total potash were reduced by adding of loess,and there was a linear correlation.In addition,among the five kinds of slop,total nitrogen content and organic matter content were for this order: semi-sunny ＞ shady ＞ sunny ＞ semi-shady ＞ platforms,and the content of rapidly-available phosphorus and available potash were for this order: semi-sunny ＞ platforms ＞ shady ＞ sunny ＞ semi-shady.The research lays a theoretical base for the future vegetation restoration.
