Abstract: Objective To analyze the distribution of suitable habitats of Parafossarulus striatulus in China based on environmental factors, and to project the impact of climate changes on the distribution of P. striatulus in China. Methods The Chinese and English literatures related to the geographical distribution of P. striatulus in China were searched in the Chinese National Knowledge Infrastructure, VIP, Wanfang Data Knowledge Service Platform, PubMed, and Web of Science, from which, the coordinate information of distribution points of P. striatulus was extracted, and the information of other distribution points of P. striatulus was obtained from the Global Biodiversity Information Facility (GBIF) combined with the required climate and geographical factors. The MaxEnt was used to project the suitable habitats of P. striatulus in China in the future under different scenarios. Results Among the environmental factors affecting the distribution of suitable habitats of P. striatulus in China, the top four contributing factors were elevation (contribution rate, 51.42%), water index (contribution rate, 11.23%), precipitation in the wettest month (contribution rate, 8.71%), and precipitation in the driest month (contribution rate, 6.82%). Under the current climate conditions, P. striatulus was mainly distributed in the southeastern and northern regions of China, and the areas of highly and moderately suitable habitats were 373 700 km2 and 616 000 km2, respectively. Under the shared socioeconomic pathway (SSP) 126 scenario, the highly suitable habitats increased by 910 000 km2 and 938 200 km2 during 2041 to 2060 and 2061 to 2080, respectively. Under the SSP245 scenario, the highly suitable habitats increased by 412 200 km2 and 494 400 km2 during 2041 to 2060 and 2061 to 2080, respectively. Conclusion Elevation is the most important environmental factor affecting the distribution of P. striatulus. Under the SSP126 and SSP245 scenarios, future climate changes are expected to expand the suitable habitats of P. striatulus to varying degrees.

摘要: 目的 结合环境因子分析纹沼螺在我国的适生区分布,并预估气候变化对我国纹沼螺分布情况的影响。方法 在中英文数据库(中国知网、维普、万方数据知识服务平台、PubMed、Web of Science)中检索我国纹沼螺地理分布相关中英文文献,从中提取纹沼螺分布点的坐标信息,同时从世界生物多样性信息交换平台(GBIF)中获取纹沼螺其他分布点信息。结合所需气候和地理因子,建立最大熵模型(MaxEnt)对不同情景模式下未来我国纹沼螺适生区进行预估。结果 影响我国纹沼螺适生区分布的环境因子中,贡献率前4位的因子为海拔(贡献率51.42%)、水体指数(贡献率11.23%)、最湿月降水量(贡献率8.71%)和最干月降水量(贡献率6.82%);当前气候条件下,纹沼螺主要分布于我国东南地区和华北地区,高适生区和中适生区面积分别为37.37和61.60万km2;在共享社会经济路径(SSP)126情景模式下,高适生区在2041-2060年和2061-2080年2个周期内将分别增加91.00和93.82万km2;在SSP245情景模式下,高适生区在2041-2060年和2061-2080年2个周期内将分别增加41.22和49.44万km2结论 海拔是影响纹沼螺分布的最主要环境因素,在SSP126和SSP245情景模式下,未来气候变化均使纹沼螺的适生区不同程度扩大。
