ABSTRACT
After summary of the distribution
data of 180,661 genera of terrestrial animals, plants, fungi, bacteria and
viruses in the world, according to the ecological conditions such as topography
and climate, the world land is divided into 67 BGUs (Basic Geographic Units),
which are analyzed by four quantitative methods: Single linkage method, Average
group linkage method, Sum of squares method and MSCA (Multivariate Similarity
Clustering Analysis) method. The MSCA has stronger data mining ability than the
first three traditional clustering methods, and can obtain more, more detailed,
more accurate and more stable clustering results. According to the clustering
results, the first world biogeographical regionalization system was
established. This system not only affirms and supports the reasonable
scientific core of the mammalian and flowering plant geographical division plan
formulated by the predecessors of scholars in the 19th century, but also
revises some imbalances in the division criteria and boundary determination
caused by their qualitative methods, unifying various global geographical
division plans emerging since the 21st century.
