摘　　要：目的分析影响我国长角涵螺分布的气候和地理因子,探索长角涵螺在我国的潜在适生区。方法检索公开发表的我国长角涵螺地理分布相关中、英文文献,从中提取地理位置信息,运用最大熵模型(MaxEnt)分析气候和地理因子对长角涵螺潜在分布区的影响,并预测长角涵螺在我国的潜在适生区。结果主要气候和地理因子中,海拔(贡献率48.80%)、最干月降水量(贡献率22.70%)和归一化水体指数(贡献率6.70%),对长角涵螺的分布影响较大。我国长角涵螺高、中、低适生区面积分别为30.64、60.60和101.00万km^(2)。其中,高适生区主要位于浙江、江苏、上海、安徽、湖南、湖北省(直辖市)等地。结论长角涵螺主要分布于我国秦岭淮河以南地区,海拔、最干月降水量和归一化水体指数可能是影响其分布的主要因素。Objective To analyze the climate and geographical factors affecting the distribution of Alocinma longicornis in China,and to predict its potential habitat areas in China.Methods English and Chinese articles reporting the geographical distribution of A.longicornis in China were retrieved for extraction of the geographic information.The impact of climate and geographical factors on the distribution of A.longicornis was analyzed and the suitable habitats were predicted using a MaxEnt model.Results Elevation(48.80%),precipitation of driest month(22.70%),and normalized difference water index(6.70%)had great influence on the distribution of A.longicornis in China.The habitats with high,medium,and low suitability were 0.3064,0.6060,and 1.0100 million km^(2),respectively.Areas with high suitability were mainly located in Zhejiang,Jiangsu,Shanghai,Anhui,Hunan,and Hubei provinces(municipality).Conclusion A.longicornis is mainly distributed in China south of the Qinling-Huaihe Line.Elevation,precipitation of driest month,and normalized difference water index are the main factors affecting its distribution.
