Abstract: Strengthening ecological restoration of historical legacy mines is not only an inevitable requirement of ecological civilization construction,but also an important measure to effectively solve people's livelihood issues and protect and restore the green mountains and clear waters.This study selects the relatively concentrated and contiguous historical legacy mines in the southern hilly and mountainous area,the northern slope of the Nanling Mountains in the Hunan section,which are in urgent need of governance,as the research object.It analyzes the main ecological and environmental problems of historical legacy mines in this area,adheres to the systematic governance thinking,and takes the prominent ecological and environmental problems of the basin as the guidance to carry out engineering layout,clarify planning indicators,engineering contents,and annual plans,and analyze the expected effects to ensure the precise implementation of ecological protection and restoration projects,making the project effects quantifiable and assessable.The implementation of the research plan will restore the land resources in the study area,reshape the landform landscape,eliminate the potential threat of geological disasters,restore the water conservation function of forest vegetation,effectively promote the improvement of the stability of the ecosystem in the study area,achieve the continuous health and improvement of the regional ecological environment system.The implementation of the research plan will provide practical basis for the ecological restoration of similar historical legacy mines.

Key words: historical legacy mines, ecological environment, ecological restoration, engineering planning
