Plot-based vegetation data have been collected in the Northern Territory since the 1950s. The purpose of data collection broadly includes land resource and vegetation community mapping, flora surveys, habitat assessment for fauna surveys, rare and threatened species surveys, development assessment and monitoring. These datasets were stored in disparate database systems until 2012. Currently over 423 surveys, 69 000 geocoded plots, comprising almost 838 164 flora records, are maintained using a corporate database. The data are of varying degrees of attribute detail including floristics, structure, strata and associated environmental information. The original territory-wide standardised vegetation classification was based on the 1:1 000 000 vegetation mapping project where 112 broad vegetation types were described from 2245 plots using an intuitive appraisal of numerical analytical techniques. This approach continues to be used; however, a standard method would be desirable to classify plot data into meaningful vegetation types in the Northern Territory. The National Vegetation Information System (vegetation hierarchy) was used to qualitatively assess the level of detail of vegetation plot data. Only 9% of the plot data can be assigned to sub-association level, and 28% to the association level. In addition to reviewing the compatibility of plot data to the National Vegetation Information System, we also provide examples of how it can conform with the International Vegetation Classification.

基于北领地的植被数据与国家植被分类系统和未来植被类型的概述和兼容性

自1950年代以来,已在北部地区收集了基于图块的植被数据。数据收集的目的广泛地包括土地资源和植被群落测绘,植物调查,动物调查的栖息地评估,稀有和受威胁物种调查,发展评估和监测。这些数据集一直存储到不同的数据库系统中,直到2012年。目前,使用公司数据库维护着423个调查,69 000个地理编码地块,包括近838 164个植物记录。数据具有不同程度的属性详细信息,包括植物区系,结构,地层和相关的环境信息。最初的全域标准化植被分类是基于1:100万植被测绘项目,其中使用直观的数字分析技术评估方法从2245个地块中描述了112种广泛的植被类型。这种方法继续被使用;但是,需要一种标准方法将地块数据分类为北领地有意义的植被类型。国家植被信息系统(植被层次)用于定性评估植被图数据的详细程度。只能将9%的绘图数据分配给子关联级别,将28%分配给关联级别。除了审查样地数据与国家植被信息系统的兼容性之外,我们还提供示例说明其如何符合国际植被分类。但是,需要一种标准方法将地块数据分类为北领地有意义的植被类型。国家植被信息系统(植被层次)用于定性评估植被图数据的详细程度。只能将9%的绘图数据分配给子关联级别,将28%分配给关联级别。除了审查样地数据与国家植被信息系统的兼容性之外,我们还提供示例说明其如何符合国际植被分类。但是,需要一种标准方法将地块数据分类为北领地有意义的植被类型。国家植被信息系统(植被层次)用于定性评估植被图数据的详细程度。只能将9%的绘图数据分配给子关联级别,将28%分配给关联级别。除了审查样地数据与国家植被信息系统的兼容性之外,我们还提供示例说明其如何符合国际植被分类。只能将9%的绘图数据分配给子关联级别,将28%分配给关联级别。除了审查样地数据与国家植被信息系统的兼容性之外,我们还提供示例说明其如何符合国际植被分类。只能将9%的绘图数据分配给子关联级别,将28%分配给关联级别。除了审查样地数据与国家植被信息系统的兼容性之外,我们还提供示例说明其如何符合国际植被分类。
