Abstract: In order to improve the situation of serious loss of ecological environment function in Lengshuijiang antimony coal mining area in Loudi City，Hunan Province，aiming at the problems of soil heavy metal pollution，low vegetation coverage and large amount of soil and water loss in the mining area， the ecological reconstruction of Yangmeiling block in Lengshuijiang antimony mine was studied. By applying a series of key technologies of geological stabilization-soil improvement-biocommunity reconstruction to lo⁃ cal land remediation，organic-inorganic composite soil remediation，arbor-shrub-herb composite communi⁃ ty construction (camphor-oleander-bermudagrass) and constructed wetland purification，the vegetation cov⁃ erage rate increased to 87%，the amount of soil erosion was reduced by 70%，and the Sb concentration in the water body reached the standard (Sb≤0.1 mg/L)，which improved the ecological environment of the min⁃ ing area and enhanced the stability of the ecosystem.

Key words: Lengshuijiang antimony coal mine area, Yangmeiling block, ecological restoration, heavy metal pollution control, tree-shrub-grass community, artificial wetland
