摘要: 为预测和分析土耳其扁谷盗[Cryptolestes turcicus(Grouville)]的潜在地理分布,研究不同时期气候环境对其分布的影响,基于土耳其扁谷盗的分布点和环境因子变量,采用MaxEnt生态位模型,预测当前时期(1950—2000年)、未来时期(2021—2040年和2041—2060年)、4种气候模式(BCC_CSM2_MR、IPSL_CM6A_LR、MIROC6、MRI_ESM2_0)、2种变化情景(ssp245和ssp585)下土耳其扁谷盗在中国的潜在地理分布和环境影响因素。结果表明:当前土耳其扁谷盗的最佳适生区面积为66.35×104 km2,主要分布于河北省、山东省、河南省、安徽省、江苏省和湖北省的大部分地区,以及广西壮族自治区等沿海区域的部分地区;高适生区面积为116.53×104 km2,主要分布于黑龙江省西部的少部分区域、吉林省、辽宁省和内蒙古自治区接壤区域、北京市南部、河北省北部、山西省南部、陕西省中部南部、河南省西南部和四川省东北部。刀切法分析(Jackknife)结果表明,8月平均最低温(Tmin8)、海拔、8月平均降水量(Prec8)和11月平均降水量(Prec11)是影响土耳其扁谷盗分布的主要因素,海拔 0~300 m、Tmin8 20~29 ℃、Prec8 100~550 mm、Prec11 15~108 mm条件下土耳其扁谷盗的发生概率高(>0.5)。在未来不同气候情景下,高适生区和最佳适生区面积总体上均呈上升趋势。与当前时期相比,在ssp245和ssp585 2种不同共享社会经济路径下适生区总面积的平均增幅分别为8.5%和4.1%;湖南省、江西省、广西壮族自治区、香港特别行政区、澳门特别行政区、广东省、福建省的大部分地区,内蒙古自治区西部、四川省东部和重庆市西部的少部分地区各等级适生区面积增加,适生区等级上升。随着未来气候变化,土耳其扁谷盗最佳适生区有从河南省、安徽省和江苏省向南扩散至湖南省、江西省和上海市等地的趋势。

Abstract:

To predict and analyze the potential geographical distribution of Cryptolestes turcicus(Grouville) and investigate the impact of climatic environments on its distribution across different periods, based on the actual distribution data of C. turcicus and the environmental variables of the current period (1950—2000) and the future period (2021—2040 and 2041—2060) with 4 climate models (BCC_CSM2_MR, IPSL_CM6A_LR, MIROC6, MRI_ESM2_0) and two shared socioeconomic pathways (ssp245 and ssp585), this study used the MaxEnt model to predict the potential distribution area of C. turcicus in China. The results indicated that the current most suitable area for C. turcicus reached to 66.35×104 km2, primarily covering most regions of Hebei, Shandong, Henan, Anhui, Jiangsu, and Hubei provinces, as well as coastal areas of Guangxi Zhuang Autonomous Region. The highly suitable area (116.53×104 km2) was mainly distributed in western Heilongjiang, border regions of Jilin, Liaoning, and Inner Mongolia Autonomous Region, southern Beijing, northern Hebei, southern Shanxi, central-southern Shaanxi, southwestern Henan, and northeastern Sichuan. Jackknife analysis identified the average minimum temperature in August (Tmin8), altitude, average precipitation in August (Prec8), and average precipitation in November (Prec11) as key factors influencing the C. turcicus distribution. High occurrence probability (>0.5) was observed under conditions of altitude 0-300 m, Tmin8 20-29 ℃, Prec8 100-550 mm, and Prec11 15-108 mm. Under different future climate scenarios, both highly suitable area and most suitable area are projected to expand.Compared with the current period, the average increases in total suitable area under the two shared socioeconomic pathways (ssp245 and ssp585) were 8.5% and 4.1%, respectively. Regions such as Hunan, Jiangxi, Guangxi, Hong Kong SAR, Macao SAR, Guangdong, Fujian, western Inner Mongolia, eastern Sichuan, and western Chongqing are expected to show increased suitability levels. Additionally, the most suitable area may shift southward from Henan, Anhui, and Jiangsu toward Hunan, Jiangxi, and Shanghai under future climate changes.
