“…Restoring ecological corridors and assessing ecosystem services are efficient measures to protect global biodiversity [ 60 , 61 , 62 ]. As global population increases, natural land cover is decreasing and most forms of ecological degradation have an overwhelmingly negative effect on biodiversity [ 63 ].…”

The ecological security pattern construction could effectively regulate ecological processes and ensure ecological functions, then rationally allocate natural resources and green infrastructure, and, finally, realize ecological security. In view of serious soil erosion, accelerated land desertification, soil pollution and habitat degradation in Shanxi Province, the spatial distribution of six key ecosystem services, including water conservation (WC), soil conservation (SC), sand fixation (SF), carbon storage (CS), net primary productivity (NPP) and habitat quality (HQ), was analyzed by using multiple models. The comprehensive ability of multiple ecosystem services in different regions was quantified by calculating multiple ecosystem services landscape index (MESLI). Combined with ecosystem services hotspots, the ecological security pattern of Shanxi Province was constructed by using the minimum cumulative resistance model. The results showed that the spatial differences in ecosystem services in Shanxi Province were obvious, which was low in the seven major basins and Fen River valley, and high in the mountains (especially Taihang and Lvliang Mountains) for WC, SC, CS, NPP and HQ, while high SF was only distributed in the northern Shanxi. The MESLI showed that the ability to provide multiple ecosystem services simultaneously was low in Shanxi Province, with the medium and low grade MESLI regions accounting for 58.61%, and only 18.07% for the high grade MESLI regions. The important protected areas and ecological sources of the ecological security pattern were concentrated in the Lvliang and Taihang Mountains, which were consistent with the key areas of ecosystem services. The ecological corridors illustrated network distribution with ecological sources as the center, the low-, medium- and high-level buffers accounted for 26.34%, 17.03% and 16.35%, respectively. The results will provide important implications for economic transformation, high-quality development and ecological sustainable development in resource-based regions worldwide.

“…It reflects the difficulty and possibility of ecological environment problems occurring in a region. By referring to the National Ecological Function Regionalization and The Technical Specification for Investigation and Assessment of National Ecological status—Ecosystem Problems Assessment [ 40 ], an ecological sensitivity evaluation index system for Jinan was built with three dimensions: soil erosion sensitivity, biodiversity sensitivity, and geological disaster sensitivity ( Table 2 ).…”

Land use conflicts exacerbate soil erosion and reduce biodiversity, which is detrimental to sustainable development. Multiple methods such as multi-criteria evaluation and landscape pattern indexes can identify land use conflicts, but few studies conform to the concept of green development. The concept of green development gives priority to ecological protection and coordinates the relationship between production development, food production and ecological protection to achieve sustainable development. Taking Jinan City (China) as the study area, we identified the ecological source areas by evaluating the importance of ecosystem service functions and ecological sensitivity, then extracted and optimized the ecological corridor network (using the minimum cumulative resistance model and gravity model), and constructed the ecological security pattern. Spatial overlay analysis of cultivated land, construction land, and the ecological security pattern was performed to identify the types and intensity of land use conflicts. Spatially, we found that ecological land was in more serious conflict with cultivated land than construction land. Different types of land use conflicts have significant differences in spatial distribution. The key to land use conflict mediation in Jinan City is to balance food security with the improvements in the quality of the ecological environment. Hence, it is necessary to delineate the main functional zones and formulate tailored land use conflict mediation strategies in each zone. The method for land use conflict identification proposed here follows the principle of giving priority to ecological protection, providing a scientific reference for the utilization and protection of territorial space in other similar areas.

“…Ecological pinch points represent areas in the corridors with the highest current density and are important nodes in ecological grid construction. In this study, the corridor weighted cost distance was set to 2000 m [52], and the current density distribution map was obtained by iteratively calculating the input currents to the source in a many-to-one mode sequence. Using the natural breakpoint method, the current intensity was divided into three levels and categorised from high to low as Level 1, 2, and 3 protection areas.…”

Urbanisation is a significant driver of global climate change. It increases global temperatures, impacting the health of residents. To date, research on urban heat environments has focused on society or ecology, overlooking the value of integrating the two factors. The research objective is to integrate socio-ecological benefits, explore the construction methods of ecological-cooling networks, and provide reasonable guidance for urban climate planning, thus contributing to the alleviation of urban heat risks and improving thermal comfort. Using Fuzhou as an example, an environmental risk framework was used to construct an urban heat environment risk assessment strategy based on hazards (thermal comfort), exposure (human-development footprint), and vulnerability (natural geographic conditions). The source area was identified based on evaluation results, an ecological network was constructed using circuit theory, and key nodes were identified. Results showed that in 2005 and 2020, 3% and 12% of areas in Fuzhou had higher thermal environmental risks, the proportion of low-risk areas was 43% and 28%, respectively. In sum, 54 ecological source locations, 124 ecological corridors, 76 ecological pinch points, 110 obstacle points, and 12 stepping stones were identified during the construction of corridors in 2020. Compared with 2005, the source area has decreased by 1622.46 km2 and the average length of the corridor has also decreased by 4.69 km.
