摘 要：
The relationship among stand shade density,vegetation coverage and Oncomelania hupensis density in Yunnan Plateau fields was studied.The results show that the number of frames with Oncomelania hupensis and Oncomelania hupensis density decreased gradually as the stand shade density increases.The living Oncomelania hupensis density is 0 when the stand shade density is above 0.8.Abundant vegetation and high coverage is favorable to Oncomelania hupensis breeding,which indicated more Oncomelania hupensis inhabited in the area with overgrown weeds and luxuriant plants.
