There is no relevant species conservation plan in place in the region, and scientific guidance on ecosystem change and corridor construction is urgently needed. In this study, we first assess ecosystem service functions based on the InVEST model; then, we assess ecological sensitivity and identify landscape resistance surfaces by constructing ecosystem sensitivity indicators; finally, we construct ecological security patterns by combining landscape resistance surfaces and circuit theory identification. The main results are as follows: (1) The high value area of ecosystem services is located in the southwest, while the northeast part of the study area has lower ecosystem services, and there is a trade-off between the ecosystem services in the study area. (2) There are 38 ecological sources in southern Anhui, with a total area of more than 5742.79 km2, that are the basic guarantees of ecological security, mainly located in the northeast of the study area, and woodland and grassland are the most important components, accounting for 18.4% of the total study area. (3) The ecological security pattern in the study area consists of 63 ecological sources, 37 important corridors, and 26 potential corridors, of which there are 28 pinch point areas and 6 barrier point patches in the study area, mainly located within Huangshan City and Xuancheng City. We recommend that when implementing restoration and rehabilitation measures in the future, policy makers should give priority to pinch points and barrier areas.<\/jats:p>","DOI":"10.3390\/rs15051385","type":"journal-article","created":{"date-parts":[[2023,3,1]],"date-time":"2023-03-01T01:36:09Z","timestamp":1677634569000},"page":"1385","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Construction and Analysis of Ecological Security Patterns in the Southern Anhui Region of China from a Circuit Theory Perspective"],"prefix":"10.3390","volume":"15","author":[{"given":"Xiaoying","family":"Lai","sequence":"first","affiliation":[{"name":"College of Management and Economics, Tianjin University, Tianjin 300072, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2912-9273","authenticated-orcid":false,"given":"Haoran","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Landscape Architecture, Nanjing Forestry University, Nanjing 210042, China"}]},{"given":"Guihua","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Poyang Lake Wetland and Watershed Research, School of Geography and Environment, Jiangxi Normal University, Nanchang 330022, China"}]},{"given":"Xiangxue","family":"Zhang","sequence":"additional","affiliation":[{"name":"Faculty of Geographical Science, Beijing Normal University, Beijing 100875, China"},{"name":"Faculty of Geo-Information Science and Earth Observation (ITC), University of Twente, 7514 AE Enschede, The Netherlands"}]},{"given":"Yu","family":"Feng","sequence":"additional","affiliation":[{"name":"School of Environment, Tsinghua University, Beijing 100084, China"},{"name":"Chinese Research Academy of Environmental Sciences, Beijing 100012, China"}]},{"given":"Yiwen","family":"Ji","sequence":"additional","affiliation":[{"name":"School of Landscape Architecture, Nanjing Forestry University, Nanjing 210042, China"}]},{"given":"Qi","family":"Zhao","sequence":"additional","affiliation":[{"name":"Hydrology Bureau of Xinjiang Uygur Autonomous Region, Urumqi 830099, China"}]},{"given":"Junyi","family":"Jiang","sequence":"additional","affiliation":[{"name":"Haikou Marine Geological Survey Center, China Geological Survey, Haikou 571127, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0563-2395","authenticated-orcid":false,"given":"Xinchen","family":"Gu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Hydraulic Engineering Simulation and Safety, School of Civil Engineering, Tianjin University, Tianjin 300072, China"},{"name":"State Key Laboratory of Simulation and Regulation of Water Cycle in River Basin, China Institute of Water Resources and Hydropower Research, Beijing 100044, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"145837","DOI":"10.1016\/j.scitotenv.2021.145837","article-title":"Coupling and coordinated development of new urbanization and agro-ecological environment in China","volume":"776","author":"Cai","year":"2021","journal-title":"Sci.
