测量的范围是范围（或程度）与分辨率的比率。范围也可以定义为给定步长或时空图上两点之间的距离的测量仪器中的步数。范围不同于规模，因为它是无量纲的，因此提供了一种跨研究可比性的手段。目的这种观点认为，推进景观生态学的尺度科学可以受益于承认和拥抱的概念范围，以促进复制，并提供联系的尺度定律。方法在景观生态学的尺度上定义范围并与现有的功能相联系。一个简单的案例研究演示了如何景观指标计算的几个扩展到颗粒比更相似的范围比颗粒或范围。结果指标分布根据范围自然分组，相同/相似的范围显示更相似的均值和分布。分布形状还根据范围显示相似性，支持使用范围进行比较和复制。关于向前推进的建议包括：根据所调查的现象确定研究的范围，报告范围和程度，以便进行范围计算，并根据范围进行比较和复制。
Context The scope of a measurement is the ratio of the range (or extent) to the resolution. Scope can also be defined as the number of steps in a measurement instrument given the step size or the distance between two points on a space-time diagram. Scope differs from scale in that it is dimensionless and thus provides a means for comparability across studies. Objectives This perspective argues that advancing a science of scaling in landscape ecology can benefit from acknowledging and embracing the concept of scope to facilitate replications and provide linkages to scaling laws. Methods Scope is defined and linked to existing focii on scale in landscape ecology. A simple case study demonstrates how landscape metrics computed for several extent-to-grain ratios are more similar according to scope than either grain or extent. Results Metric distributions naturally group according to scope, with same/similar scopes displaying more similar means and distributions. Distribution shapes also show similarities according to scope, supporting the use of scope for comparisons and replications. Conclusions Recommendations for moving forward include setting the scope of a study based on the phenomenon under investigation, reporting grain and extent to permit scope calculations, and undertaking comparisons and replications based on scope.
