Abstract: |
Urban biodiversity is an important part of global
biodiversity, one of the important indicators for evaluating the
health of urban natural systems, and an important support for
maintaining ecological security and ecological balance of cities
and improving urban habitat. The rapid urbanization development
has caused a huge impact on urban biodiversity, and as an urbanrural border area of the capital, it is of great practical importance
to explore the conservation and enhancement of urban biodiversity
in the second green belt of Beijing. Birds are important indicator
taxa for studying urban biodiversity because of their wide
distribution, environmental sensitivity and easy observation. In this
study, the biodiversity of the research area was evaluated by using
a GIS platform and the InVEST model to synthesize theoretical
simulation results and actual observation data of birds, and it was
found that the research area has a good ecological background,
among which bird resources are particularly rich, but it is highly
disturbed by human beings and shows the characteristics of
isolation and fragmentation. Based on the evaluation results, it is
proposed to build a biodiversity conservation planning system of
"grading, zoning, and networking", and the conservation planning
is implemented in three aspects: "core protection", "quality and
greening" and "network connectivity", which will provide some
reference for the construction of urban biodiversity conservation
planning system. |
