Abstract: |
With the global warming, biodiversity decrease, habitat
fragmentation and other increasingly serious environmental
problems, countries and regions along the "Belt and Road" face
common challenges in promoting ecological civilization. Under
the condition of limited resource, how to build an distributed
green infrastructure (GI) network reasonably to meet the demand
of human well-being is still the focus of current researches and
the main problem of landscape management practice. Taking Alar
City in Xinjiang as an example, this study identifies the hubs and
corridors that have an important impact on the landscape ecological
pattern based on the morphological spatial pattern analysis and
least-cost path analysis. After that, the network is further optimized
through supplementing ecological strategic nodes, and then
combining with the actual situation of the region, the idea of GI
network construction will be put forward. The results can form the
theoretical and empirical foundation for ecological restoration and
green system planning in Alar City or Aksu Area, and also provide
ideas and methods for GI network and ecological security pattern
construction for other cities and towns of arid areas along the "Belt
and Road". |
