摘要

本文应用最大熵(MaxEnt)算法估计了摩洛哥马尔莫拉森林中栓皮栎(Quercus suber L.)的当前和潜在分布,为地中海盆地气候变化条件下的保护提供了依据。总共使用了1428个软木橡树位置的实地空间记录(海拔和19个生物气候环境变量)来模拟软木橡树的潜在分布。调整后的模型具有良好的预测质量(曲线下面积=0.81)。一年中最潮湿季度的降水量、降水的季节性、海拔高度和温度的季节变化是决定马莫拉森林软木橡树分布的关键因素。目前适合种植软木橡树的大多数地区位于西部和中部的马莫拉森林地区,那里的生物气候潮湿,并受到来自大西洋的大量海风。离开海洋后,湿度降低,温度升高,软木橡树在适应和再生方面面临困难。研究结果可用于确定软木橡树恢复和保护的高度优先领域,以应对气候变化的预期影响。

Prediction by maximum entropy of potential habitat of the cork oak (Quercus suber L.) in Maamora Forest, Morocco
In this paper, the maximum entropy (MaxEnt) algorithm was applied to estimate the current and potential distributions of cork oak (Quercus suber L.) in the Maarmora forest of Morocco to provide a basis for its conservation under climate change conditions in the Mediterranean basin. A total of 1,428 field-based spatial records of cork oak locations were used (altitude and 19 bioclimatic environmental variables) to model the potential distribution of the cork oak. The adjusted model had a good predictive quality (area under the curve=0.81). Precipitation during the wettest quarter of the year, seasonality in precipitation, altitude, and seasonal variations in temperature were the key factors determining the distribution of the cork oak in the Maamora forest. Most areas with currently suitable conditions for cork oak were located in the western and central Maamora forest regions, which enjoy a humid bioclimate and receive significant sea spray from the Atlantic Ocean. Moving away from the ocean, the humidity decreases, and the temperature increases, such that the cork oak faces difficulties in adapting and regenerating. The results can be used to identify the high-priority areas for cork oak restoration and conservation of this species against the expected impact of climate change.
