摘　　要：本文通过对鄱阳湖上、中、下游6块洲滩的钉螺、植被和土壤的调查分析,揭示了湖区洲滩钉螺分布与苔草群丛的总盖度、高度、种盖度呈显著正相关,r为0.7842;与土壤的比重,容重呈显著负相关,r分别为-0.8751、-0.9548。可应用上述3项指标来推断洲滩钉螺分布的现状,及预测改变钉螺孳生坏境的灭螺效果。This paper reported the investigation and analysis on snail distribution,plantation and soil property of 6 districts of marshlands in upper,middle and low reaches of Poyang Lake. The results showed that there was a significant positive correlation (r=0.7842) between snail distribution and Carex Sp. Ass(including total coverage,height and species coverage), significant negative correlation between snail distribution with specific gravity and unit weight of soil,the correlation index was-0.8751 and -0.9548 respectively.It showed that the inference of snail distribution in marshlands,the environment for snail breeding and effec-tiveness of snail control can be predicted by the three indices.
