描述----------Description----------
Performs taxonomic valuation of species names according to synonomy, taxonomic level, unambiguity of biotic content etc. Necessary prerequisite is information about taxonomic status (synonomy) and hierarchy (next higher aggregat). Until now only applicable for reference list 'GermanSL' (>= vers. 1.1, see References Section), which is applicable in Germany and adjacent countries.
物种名称进行分类评估，根据分类级别，synonomy，明确性的生物量等必要的先决条件是分类学的状态（synonomy）和层次结构（一个更高的骨料）的信息。到现在为止，只适用于参考名单“GermanSL（> =版1.1，请参阅参考资料一节），这是适用于德国和邻近国家。

详细信息----------Details----------
Working with vegetation datasets, especially from different sources needs taxonomic valuation. The function tries to automate this process. Therefore the German taxonomic reference list (GermanSL, http://geobot.botanik.uni-greifswald.de/reflist/ ) contains additional taxon attributes (tax.dbf) and monotypic taxa of Germany (monotypic.dbf). Without an appropriate species list (see tax) the function will not work.
工作与植被数据集，尤其是从不同的来源，需要分类的估值。的函数试图自动完成这一过程。因此，德国分类参考的的列表（GermanSL，http://geobot.botanik.uni-greifswald.de/reflist/），包含附加的类群的属性（tax.dbf）和单种属植物的德国（monotypic.dbf）。如果没有适当的物种名单（见tax）的功能将无法正常工作。
Before we replace synonyms we can choose to evaluate the data under a different taxonomical concepts than the original GermanSL. In the moment only an outline of such an approach is realised, because complete lists of differing taxonyms and there taxonomical re-evaluation have to be provided which are not available. With the inbuild test-dataset and the interpretation of the Armeria maritima complex you can have a shot on applying different concepts using a dataset referenced with GermanSL and using Korneck1996.dbf. See package vignette.
在我们替换的同义词，我们可以选择的数据进行评估，根据不同的分类学概念比原来的GermanSL。在那一刻，只有一个轮廓实现，因为这样的做法有不同的taxonyms和分类学重新评估的完整列表，必须提供不提供。随着inbuild阿梅里亚船运复杂的测试数据集的解释中，你可以有一个镜头上应用不同的概念，使用与GermanSL引用的数据集和使用Korneck1996.dbf。包小插曲。
The three possible values for synonyms and child/parent taxa are: preserve: Leave everything untouched; conflict: Dissolve only in case of conflicts, e.g. if a subspecies occurrs also at the species level within the same dataset. In this case the subspecies will be aggregated to the higher level. adapt: All respective taxa will be adapted, e.g. set to species level.
三个可能的值为同义词和子女/父母类群的：preserve：让一切不变，“conflict：只有在冲突的情况下溶解，例如如果一个亚种发病也有相同的数据集内的物种水平。在这种情况下，亚种会被聚合到更高的水平。 adapt：所有各自的类群进行调整，例如设置到种。
Monotypic taxa, e.g. a species which occur only with 1 subspecies in the survey area. They have to be combined, since otherwise two different (valid) taxa would denominate the same entity. If lower the higher taxon (e.g. species rank) is replaced by the lower level (subspecies rank). If neither lower nor higher monotypic species are preserved. Since the list of monotypic species strongly depends on the considered area you have to choose, which area is covered by your database and create an appropriate list of monotypic taxa. Within the package "monotypic-D.dbf" is provided as a compilation of monotypic species within the GermanSL list (see tv.mono.
单型类群，例如一个物种，仅发生1亚种在调查区域。他们必须结合起来，因为否则的话两个不同的（有效的）的类群命名的实体。如果较低的较高级分类单元（例如物种秩）被替换为在较低的水平（亚种等级）。如果没有lower也不higher的单型种被保留。列表中的单型种，在很大程度上依赖于所考虑的区域，你必须选择你的数据库所涵盖的区域，并创建一个适当的列表中的单种属分类群。在包"monotypic-D.dbf"作为一个汇编的单型种内的GermanSL的名单（见tv.mono。
Option maxtaxlevel determines the maximum taxonomic level within the given names, which should be used. All higher taxon observations are deleted. If you have a single field observation determined as Asteraceae spec. all your obervations of taxa from that family will be aggregated to the family level, if you choose ag=conflict.
选项maxtaxlevel确定在给定的名字，应使用的最大级别的分类。所有较高级分类单元的意见都将被删除。如果你有一个单一的野外观测确定为菊科规范。您的obervations属植物，家庭将汇集的家庭，如果你选择AG =冲突。
值----------Value----------
Functions return the input dataframe of observations with harmonised taxon numbers.
函数返回的观测输入数据框的统一的分类单元数。
