建设的关键。以6个特大(超大)城市都市区为研究对象，基于
MSPA-InVEST复合模型对生态空间进行识别和评价，通过
生境质量评价结果提取核心生态源地并生成生态阻力面，运用
最小累计阻力模型(MCR)构建各特大城市都市区生态空间网

| Abstract: |
| In the construction of ecological civilization, as
an important site carrying information and capacity in urban
ecological space sphere, ecological space plays a fundamental
role in promoting the formation of reasonable spatial structure of
megacity, and is also the key to high-quality urban development
and high-quality habitat planning and construction. Taking the six
metropolitan areas as examples, this research couples MSPA and
InVEST models to identify and evaluate ecological space, selects
habitat source areas and constructs the resistance surface based on
the results of the habitat quality evaluation, and uses the Minimum
Cumulative Resistance (MCR) model to construct ecological space
network of metropolitan areas. On this basis, combined with the
analysis of the evolutionary trend of ecological spatial structure in
megacities, it proposes optimized structural patterns of ecological
space, and constructs two models of ecological space optimization
in metropolitan areas, namely, radial pattern of networking with
"wedge-ring" and grid pattern of networking with "core-belt",
in order to provide theoretical support and practical guidance
for optimization of ecological space pattern and sustainable
development of metropolitan areas in China, as well as to provide
certain references and bases for the optimization of territorial space
pattern of megacities. |
