Construction and optimization strategy of ecological security pattern in plain cities:A case study of Fuyang City
Under the concept of ecological civilization,constructing ecological security pattern is crucial for maintaining biodiversity.Taking Fuyang City as an example,this study used MSPA (morphological spatial pattern analysis) methodology and circuit theory to construct an ecological security pattern.The results showed that:(1) The core area determined by MSPA analysis was 87.26 km2,accounting for 56.00% of the prospective factors.(2) By analyzing the connectivity of patch landscape,28 ecological source areas were selected,with a total area of 79.98 km2.(3) There were 66 ecological corridors in total,and the corridor network from the southeast to the northwest had good ecological quality and less connection obstruction.(4) There were a total of 15 ecological pinch points in Fuyang City.Except for Linquan County,other areas had ecological pinch points,and Yingshang County had the most,with 7 pinch points.(5) There were a total of 93 obstacle zones in Fuyang City,with a total area of 2394.92 km2,which mainly distributed along the Quanhe River and the Ying River.As a typical plain city,the surface com-position of Fuyang City is relatively single and homogeneous.It is more targeted to use circuit theory to simulate the ecological security pattern of the city.By actively maintaining and protecting ecological pinch points and gradually removing ecological barriers,the overall construction of Fuyang's ecological security pattern can be promoted.
