“…Branches, which are interruptions of the bridge connection , also accounted for a relatively high proportion. Loops can facilitate species movements within the same patch (An et al 2020), but they had the lowest proportion in the study area, even decreasing to zero in 2018. Cores can serve as ecological source areas, while bridges can enhance the connectivity among cores (Velázquez et al 2017).…”

“…To measure the connectivity of historical forests and identify the important core areas and bridges in the landscape, the probability of connectivity (PC) index and the importance values of the patches (dPC) were calculated with Conefor software (Saura and Torné 2009). The PC index can reflect habitat loss and landscape fragmentation well and is widely used in connectivity analysis (An et al 2020;Laita et al 2011;Velázquez et al 2017). In this study, the dPC values of only cores, bridges, and islets with areas larger than 3 ha were evaluated for the connectivity of historical forests in the built-up area.…”

Background: Remaining historical forests are crucial for maintaining biodiversity in urban areas. However, the integrity and stability of historical forests are affected by land use/cover change in various ways. A better understanding of these impacts can help guide targeted conservation. Methods: In this study, we estimated the loss of forestlands and levels of threats and analysed the importance of critical areas for historical forests in the built-up area of a rapidly urbanizing city—Guiyang, China. Results and Conclusions: The results showed that 1988.46 ha of historical forestlands was transformed into other land use/cover types. The number of patches smaller than 10 ha increased by 51% from 1976 to 2018. The lands of 36 historical forest patches were completely transformed into other land use/cover types during the past 42 years. The mean value of the threat index of all the historical forest patches increased by 33% compared to the baseline year. Core and bridge areas regarded as key nodes and links for the connectivity of forest networks decreased in area by 632.34 and 331.92 ha, respectively. Most of the critical areas with high importance values for connectivity were located in the central part of the city. They were severely threatened by the surrounding areas, having high threat index values. Based on these findings, we recommend that effective measures be implemented to control the further loss of historical forests and increase the connectivity and buffering capacity of the remaining forests by planting trees in some key locations.

“…In recent years, regional ENs play an important role in biodiversity conservation. An et al (2021) constructed ENs for the conservation of Asian elephants affected by human disturbance, with a special focus on the importance of steppingstones. The results showed that the source areas could be effectively determined through the integration of morphological spatial pattern analysis and the patch importance index.…”

“…With the development of science and technology and population growth, large-scale urbanization has occurred worldwide in the past few decades, which has also exacerbated many environmental problems such as global warming, vegetation destruction, the sharp decline in biodiversity, and disorder of biogeochemical cycles [1][2][3]. According to United Nations projections, more than 66% of the world's population will live in cities, posing a challenge to a stable and sustainable human society-natural coupling ecological security [4].…”

Located in an ecologically fragile area in China’s eastern part of the Loess Plateau, Shuozhou City has faced environmental challenges imposed by frequent urban expansion and mining activities in recent years. As ecological security patterns (ESP) identification and optimization are significant to regional biodiversity and ecosystem services, this study combined morphological spatial pattern analysis (MSPA) and circuit theory to construct and optimize regional ESP. Results show the number and area of ecological sources in the study area decreased from 21 to 20 between 2010 and 2017. The total area of ecological sources fell from 1923.35 km2 to 1869.37 km2, with their proportion in the study area dropped from 18.14% to 17.64%. From 2010 to 2017, the number of obstacles increases from 63 to 80, mainly consisting of farmland, unused land, transportation land, and construction land. The area of obstacles reached 10.17 km2 in 2017. A framework of “one protection area, two regulation areas, and three restoration areas” is proposed to optimize the ESP of the study zone. This study explored a combination of ESP analysis tools and focused on improving regional ecosystem service and biodiversity. It will support local urban planning and provide a reference for similar studies in resource-based cities.
