description The invention discloses a method for optimally extracting available heavy metals in soil by a response surface method. The method comprises the following steps of drying, smashing and sieving soil, and obtaining a soil sample; adding a soil sample into an extracting agent, carrying out ultrasonic extraction, setting extracted variable parameters by using a response surface method, and carrying outsuction filtration after the ultrasonic extraction is finished, thereby obtaining an extracting solution containing available heavy metals. According to the method, the optimized effective-state heavy metal extraction conditions are obtained through the response surface method, so that the operation of extracting the effective-state heavy metal in the soil is simple and convenient, the extractiontime is shortened, the extraction rate of the effective-state metal is increased, the time is saved, and prevention and treatment of soil heavy metal pollution are facilitated. 本公开公开了一种响应面法优化提取土壤中有效态重金属的方法，包括以下：将土壤干燥、粉碎、过筛，得到
