Predicted suitability for EUNIS habitat types (100m resolution) for EU27 countries

The modelled suitability for some of the EUNIS terrestrial habitat types is an indication of where conditions are favorable for each habitat type based on classified sample plot data European Vegetation Archive (EVA), predictors, and the Maxent software package (https://biodiversityinformatics.amnh.org/open_source/maxent/). The modelled suitability maps may be used as a proxy for the potential geographical distribution of the habitat types in given environmental and climatic envelopes. Note however that the suitability is not representing the actual distribution of the habitat types. Currently for one time period (2010-2014) models have been created. For each period different versions for some of the predictors have been applied (LAI, LULC, Phenology, Population density). Climate, soil and topography predictors are the same for the two periods. In Maxent the models have been ran using the predictors for the second period for the future predictions.

基于欧洲植被档案（European Vegetation Archive, EVA）的分类样地数据、环境预测变量与Maxent软件包（https://biodiversityinformatics.amnh.org/open_source/maxent/）构建的模型，针对部分欧洲自然信息系统（European Nature Information System, EUNIS）陆地生境类型生成的适宜性评分，可用于指示各生境类型的适宜生长条件分布区域。该模型输出的适宜性分布图，可作为给定环境与气候生态幅下各生境类型潜在地理分布的替代指标。但需注意，该适宜性评分并不代表生境类型的实际分布情况。目前已针对单个时间段（2010-2014年）构建了模型。针对不同时间段，部分预测变量采用了不同版本的数据：叶面积指数（Leaf Area Index, LAI）、土地利用/土地覆盖（Land Use/Land Cover, LULC）、物候（Phenology）、人口密度。气候、土壤与地形预测变量在两个时间段中保持一致。在Maxent软件中，未来预测所使用的模型是基于第二时间段的预测变量构建的。
