摘　　要：在生态文明理念下,构建生态安全格局对生物多样性的维护至关重要。本研究以阜阳市为例,利用MSPA方法与电路理论,构建了生态安全格局。研究结果表明:(1)MSPA分析确定的核心区面积为87.26km^(2),占前景要素的56.00%。(2)通过斑块景观连通性分析,筛选出了28个生态源地,总面积为79.98km^(2)。(3)共有66条生态廊道,东南至西北方向形成的廊道网络生态质量良好,连接受阻较少。(4)阜阳市内共有15个生态夹点,除临泉县外,其他地区均有生态夹点,其中颍上县最多,有7个夹点。(5)阜阳市内共有93个障碍区,其斑块面积均在0.2 km^(2)以上,总面积达2 394.92 km^(2),主要分布在泉河和颍河沿线。阜阳市为典型的平原城市,地表构成相对单一且均质,采用电路理论模拟城市的生态安全格局,更具针对性。通过积极维护和保护生态夹点,并逐步消除生态障碍,可促进阜阳市生态安全格局的全面建设。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 km^(2),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 km^(2).(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 km^(2),which mainly distributed along the Quanhe River and the Ying River.As a typical plain city,the surface composition 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.
