“…The restricted evaluation indicators of the PSR model are mostly statistical indicators related to the economy, environment, and nature [ 14 , 15 ]. Although they can respond to the relationship between the cultivated land ecosystem and human social development to a certain extent, they ignore the spatial pattern of the cultivated land itself and the influence of the surrounding environment [ 12 , 16 ]. In terms of cultivated land utilization, in recent years, with the proposal of the concept of “production-living-ecological (PLE)” space, the core of land use optimization has gradually changed from “quantity-space” to “structure-function”.…”

In order to achieve the coordinated development of ecological protection and cultivated land use, ecological security and cultivated land use functions (CLUFs) in the study area were evaluated by constructing a comprehensive evaluation index system. The leading CLUFs were measured, and it was determined to use the normalized revealed comparative advantage (NRCA) index. The spatial superposition analysis of the ecological security level and the leading CLUFs was carried out to obtain the zoning of the coordinated development of ecological security and cultivated land use, and differentiated utilization strategies were proposed for different zones. The results of this study showed the following: (1) The ecological security level of cultivated land in Yuanyang County can be divided into high, medium, and low security levels, accounting for 30.68%, 43.42%, and 25.9% of the total cultivated land area, respectively. The overall ecological security level is high. (2) The current cultivated land use mainly has a production function, accounting for 38.39% of the total cultivated land area, the leading CLUFs that are 34.16% of the cultivated land are the ecological function, and 27.45% of the cultivated land is the living function. (3) The spatial superposition analysis of the ecological security level and leading CLUFs yielded four zones of cultivated land use enhancement, including a production core zone, and different control strategies were proposed for the different zones. These strategies may help to fully realize the multifunctionality of the cultivated land without compromising ecological protection. Implementing differentiated protection for cultivated land in different use zones can achieve the coordinated development of ecological protection and cultivated land use, thus promoting the sustainable use of cultivated land resources.

“…Urban ecological security has been attracting the attention of scholars in relevant fields, including urban ecological security evaluation (Xie and Li, 2004;Zhou and Wang, 2005;Li et al, 2019;Ke et al, 2021;Wen and Hou, 2021;Cheng et al, 2022) and pattern (Peng et al, 2017;Peng and Zhou, 2019;Gao et al, 2020;Lu et al, 2021;Nie et al, 2021;Wang S. et al, 2021;Gao et al, 2022;Gou et al, 2022;Li et al, 2022;Wei et al, 2022), "anti-planning" (Yu et al, 2005(Yu et al, , 2009, and ecological infrastructure planning (Tubridy, 2020;Romero-Duque et al, 2020;Huang et al, 2022). Among them, the ecological security pattern (ESP), which uses the principles and methods of landscape ecology and geographic information system (GIS) technology to quantitatively describe the landscape structure in space, shows strong application potential in the field of urban planning.…”

The high-intensity development of a city encroaches on the ecological land, such as lakes, rivers, and forests, which changes the stable land relationship, resulting in ecological security problems, such as regional waterlogging and a decline in biodiversity. Identifying urban ecological systems and constructing ecological security patterns (ESP) are of great importance for urban ecological protection and spatial planning. The complexity of the ecological environment in landscape cities makes them more difficult for planning and construction than in plain cities. Additionally, they are more susceptible to torrential rains, mountain torrents, and river tides in the process of urbanization. This study introduced the functional wetland theory into the construction of the ESP and obtained a new set of methods for landscape cities. Based on the functional wetland theory, the “patch-corridor-matrix” model was used to combine the geographic information system (GIS) runoff and catchment analysis with the MSPA-MCR ecological corridor construction method to form a new wetland and habitat network by coupling the two together. Additionally, construction principles of protection priority, maximization of ecological benefits, guarantee of connectivity, and targeted design to guide the construction of landscape cities were put forward. This study takes the central urban area of Fuzhou as an example to show the application path of this method.

“…Such artificial disturbance has greatly changed the original landscape pattern, and it is also a typical case in landscape ecology research (Ke et al, 2021). However, most of the existing literature focuses on research on a larger scale, and there are few studies on the landscape ecological security of such typical districts and counties (Wen & Hou, 2021). So, this study based on the ecosystem service value, land use diversification index and landscape index, and established a "functionality-organization-stability" landscape ecological security assessment framework, taking Zhong County as the research object, a typical county in the Three Gorges Reservoir area, to evaluate the ecological security by superposition method.…”

The spatial-temporal heterogeneity of landscape ecological security has been carried out for the Zhong County in this work based on the framework of “functionality-organization-stability” using the multidate Landsat TM image of 2000, 2006, 2012 and 2018 as the basic data. During the research period, landscape ecological security situation in Zhong County indicates a trend of deteriorating. The high ecological security zone was constantly shifting to the low ecological security zone from 2000 to 2018. The ratios were 13.40%, 61.32%, 28.34%, and 13.33%. The low ecological security area in research area focuses on the northeast part and middle part, while the high-security area focuses on Yangtze river way and its both sides and Northwest. The main obstacle factor of landscape ecological security transfers into stability from functionality. Therefore it suggests to optimize land use pattern in landscape planning and construction in the future in order to raise the landscape ecological security level.
