摘　　要：利用地热资源养殖甲鱼，水体温度控制在３０℃±０５～１℃的基础上，采用由调节阀、水空气引射器和中间调节池组成水质改良装置，可使养殖水体中的有害物质明显减少，溶氧经常保持３ｍｇ／Ｌ以上，稚鳖的平均增重和成活率大幅度提高。In culturing the turtle(Amyda sinensis) by using geothermal energy resource, the temperature of the breeding water was controlled at 30℃±0 5～1℃; By using the water quality improving equipment which was consisted of regulating valve, water air injector and aerate pool, the dissolved oxygen in the breeding water was controlled above 3mg/L at most time, the endangering substance was also dilimited apparentlg, and the average weight improving and the survival rate of young turtle were improved greatly.
