Bioclimate of Italy: application of the worldwide bioclimatic classification system

The worldwide bioclimatic classification system (WBCS) of Rivas-Martínez was applied to the Italian territory and surrounding areas between latitudes 35°47′–46°60′ N and longitudes 5°92′–21°39′ E. The ‘WorldClim’ precipitation and temperature dataset was used as the source data. Application of the WBCS in a geographic information system allowed the production of macrobioclimates, bioclimates, ombrotypes, continentality, compensated thermicity index and ombro-evaporal index maps at a scale of 1:5,500,000, and a map of thermotypes at a scale of 1:2,250,000. Moreover, the isobioclimates of Italy are identified and quantified in terms of areas. These maps are available here as raster datasets (1 km spatial resolution) and are useful for: (i) rapid bioclimatic diagnosis of the Italian territories; and (ii) vegetation–environment relationship modeling at the national scale.

本研究将里瓦斯-马丁内斯（Rivas-Martínez）提出的全球生物气候分类系统（Worldwide Bioclimatic Classification System, WBCS）应用于意大利领土及周边区域，该区域的纬度范围为35°47′N至46°60′N，经度范围为5°92′E至21°39′E。本研究采用WorldClim降水与气温数据集作为源数据。借助地理信息系统（Geographic Information System, GIS）对WBCS的应用，成功生成了比例尺为1:5,500,000的大生物气候区、生物气候区、降水型、大陆度、补偿热指数及降水蒸发指数分布图，以及比例尺为1:2,250,000的气温型分布图。此外，本研究还对意大利境内的等生物气候线进行了识别，并以面积为单位对其进行了量化统计。上述地图以空间分辨率为1千米的栅格数据集形式公开提供，可应用于以下场景：（i）意大利领土的快速生物气候诊断；（ii）国家尺度下的植被-环境关系建模。
