| Abstract: |
| The GI evaluation index system at the city-level can be
structured to objectively evaluate the current status and grading of the city
GI. It can provide useful reference on understanding the current status of
multi-city GI ecological networks, GI network's positioning within the
region and cross-city ecological network planning. This study constructed a
city GI network evaluation system, which included 3 first-level indicators:
landscape composition, landscape pattern and urban development, and
used the literature review method and cluster analysis to screen and
determine the secondary indicators, completed the weight assignment
of each index using the analytic hierarchy process-variation coefficient
method, and finally formed a regional GI network evaluation index system.
This study took 13 major cities in Sichuan in the Chengdu-Chongqing
city group as study areas to apply the evaluation index system. Firstly,
based on the Morphological Spatial Pattern Analysis (MSPA) to accurately
identify the structural elements of GI networks in each city, it analyzed
the various landscape composition indicators, and used Fragstats to obtain
the landscape pattern indicators. The urban development indicators were
determined based on the relevant materials of Sichuan Province Yearbook.
Secondly, the weighted superposition method was used to quantitatively
analyze and assess the current status of GI networks in 13 cities based
on the evaluation index system, and the GI network level was divided.
Finally, the GI status characteristics of each city were summarized, and
corresponding planning control and protection suggestions were proposed
according to different GI network levels. |
