摘要:

探究软紫草(Arnebia euchroma)在中国的潜在适生区分布和其生态适应性,旨在为软紫草的野生植物资源保护及合理开发利用提供理论依据。本研究基于MaxEnt模型和ArcGIS软件,对软紫草在中国的51个分布点和11个环境因子进行潜在适生区预测,探讨影响软紫草分布的主要环境因子,并预测其在当前(1970—2000年)与未来(2021—2040年、2041—2060年)不同气候情境下的潜在适生区。结果表明:最湿季度平均温度(bio8)、季节性降水量(bio15)、最暖季度平均降水量(bio18)和海拔(elev)是影响软紫草分布的主导环境因子,贡献率分别为36.2%、13.9%、10.1%、8.5%;当前气候背景下,软紫草在国内主要分布于新疆中部和西藏西北部,潜在适生区总面积为96.26×104 km2;与当前时期相比,未来4个时期气候情景下软紫草的潜在适生区分布变化不明显,适生区总面积呈减少趋势,但高适生区面积略有增加。

Abstract:

This study explored the potential distribution and ecological adaptability of Arnebia euchroma in China and provides a theoretical basis for the protection, rational development, and use of wild plant resources of A. euchroma. Based on the MaxEnt model and ArcGIS software, 51 distribution points and 11 environmental factors of A. euchroma in China were predicted as potentially suitable areas, and the main environmental factors that influence the distribution of A. euchroma were discussed. The potentially suitable areas in China were predicted under the present (1970-2000) and future (2021-2040, 2041-2060) climatic conditions. The results showed that precipitation of mean temperature of wettest quarter, precipitation seasonality, precipitation of warmest quarter, and elevation were the dominant environmental factors that affect A. euchroma distribution, with contribution rates of 36.2%, 13.9%, 10.1%, and 8.5%, respectively. Under the current climate background, A. euchroma in China is mainly distributed in the central part of Xinjiang and the northwest part of Xizang, with a total potential habitat area of 96.26×104 km2. Compared with the current period, the climate scenarios of the next four periods did not significantly change the distribution of potentially suitable areas for A. euchroma. The total suitable area decreased while the highly suitable area increased slightly.
