This article presents a synthesis of the relationships between plants and climates at the scale of France, based on a probabilistic classification of 1874 bio-indicators. This classification defines plants groups that indicate the climate, named phytoclimates, expressing the climatic gradients in France. This classification shows 210 phytoclimatic groups distributed into ten cluster levels. The analysis of the various hierarchical levels shows two main phytoclimates testifying the importance of the marine masses and the altitude. The analysis of the third hierarchical level underlines particular phytoclimates which would not be easily recognizable by only analysing the overlapping of floristic and climatic territories. This classification allows one to select taxa that are indicators of the climate. The distribution monitoring or modeling of these taxa should show the effects of the global change on the ecosystems.
本文基于对1874种生物指标的概率分类，呈现了法国尺度下植物与气候之间的关系综合情况。这种分类定义了指示气候的植物群组，即植物气候类型，它表达了法国的气候梯度。该分类显示有210个植物气候类型分布在十个聚类层级中。对各个层级的分析表明，有两种主要的植物气候类型证明了海洋水体和海拔的重要性。对第三层级的分析强调了一些特殊的植物气候类型，仅通过分析植物区系和气候区域的重叠情况不容易识别这些类型。这种分类使人们能够选择作为气候指标的分类群。对这些分类群的分布监测或建模应能显示全球变化对生态系统的影响。
