Biodiversity has been considered at the multilevels of in landscape

ecosystem

species and genetics

respectively. How to monitor biodiversity in this multilevel 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 agriculturalforest 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 agriculturalforest 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.
