Multiscale Analysis on Agricultureforest Biodiversity in Shunyi District
Biodiversity has been considered at the multilevels of in landscape
ecosystem
species and genetics
respectively. How to monitor biodiversity in this multilevel is an important scope in the recent biodiversity research. This study took Shunyi District
Beijing
as a research region and analyzed the landscape pattern
community structure
species biodiversity in agriculturalforest landscape through ArcGIS software and field investigation. It indicated that the landscape patch showed characteristics of small size
large number
simple shape
low species richness and Shannon index for farmland landscape. The agriculturalforest compound landscape has higher species richness and Shannon index was higher than those in farmland. The cultivated forest has the smallest size with high variation among patches and complex shape
these traits was negative for constructing a steady forest community. As for natural forest
patches with large size and high connection resulting from human protection were positive for biodiversity
thus
the species is rich in various space. It was concluded that it is effective to combine multimethods to monitor the biodiversity of the same region from various biodiversity levels.
