Using the breaking-point formula and the distance-decay effect, the author develops a quantitative approach called "simple computational method".
根据断裂点公式、距离衰减效应的“简单计算方法”可以定量分析都市区的地域范围。

One of them, the so-called distance-decay theory, states that the similarity and correlation between species at two locations decreases as the distance between them increases.
该理论认为物种之间的相似性和相关性随着距离的增大而减小。
