The invention provides a karst area reservoir full-reservoir-basin anti-seepage treatment construction method. According to the difference of reservoir area terrains and different seepage characteristics, seepage preventing is conducted through a full-reservoir-basin full-laying anti-seepage method adopting reservoir bottom anti-seepage layer laying, reservoir bank sprayed concrete anti-seepage plate laying and concrete blocking. By selecting partition anti-seepage measures, local materials and excavated materials are sufficiently utilized to serve as protective layers for anti-seepage film laying at the reservoir bottom area, the construction method is simple, practicable, feasible and effective, and the good economical benefits are achieved. According to the difference of the reservoir area terrains and the different seepage characteristics, seepage is controlled to the largest extent through the combined anti-seepage method adopting reservoir bottom anti-seepage film and reservoir bank sprayed concrete ant
