Abstract: In order to better conduct the land reclamation plan of ionic rare-earth mine in Southern China，characteristics of land destruction was introduced based on the land reclamation plan on compiling regulation.Taking an ionic rare-earth mine as a case，the land destruction of this type of mine was introduced，and the design characteristics in reclamation time sequence，overburden stripping and stockpiling，in-situ leaching mining stope drainage engineering，risk fee，etc were summarized，comparison between different reclamation method was conducted.It can be concluded that ionic rare-earth reclamation includes two areas:land that will be destroyed and that have already been destroyed.For land that will be destroyed，influence of leaching solution leaking on plant roots and groundwater was considered combined with in-situ leaching characteristics，and water collecting and drainage system and extracting risk fund should be emphasized; For land that have already been destroyed，investigation on characteristics，degree，size and site condition of land being damaged should be made，combining with the current situation of abandoned mining area.

Key words: Ionic rare-earth mine, In-situ leaching mining method, Land reclamation
