Ecological network construction and optimization is an effective way to balance the contradiction between regional development ecological protection in process of urbanization. The urban–rural fringe both a frontier zone direction urban expansion important space for improving environment. However, there are few studies on how construct optimize networks fringe. In this paper, morphological spatial pattern analysis (MSPA) minimum cumulative resistance model (MCR) were firstly employed initially reveal characteristics problems security study area. Then, new strategy with multi-scenario coupling gradient zoning was proposed meet maximization integrated benefits future protection. results show that: (1) Urbanization caused high fragmentation patches, exerted strong hindrance processes. (2) distribution constructed extremely uneven, communication north–south severely difficult. optimized significantly improved respect, priority corridors will also help strengthen gradient.

The National Ecological Barrier Zones are an important part of China's ecological security strategy. construction a scientific and reasonable pattern (ESP) is for the healthy development national barrier zones. existing literature does not consider impact potential changes in ecosystem health land use on ESP construction. In this study, we considered typical composite area, Sichuan-Yunnan barrier, to analyze such areas; probability future growth change, circuit theory, service trade-off synergy, construct sustainable ESP. Spatial heterogeneity was observed level barrier; high-value areas were mostly distributed central southern parts study but low-value northeastern western regions. contained 246 sources (distributed forest grassland contiguous south, central, northeast regions), 563 corridors that portrayed obvious differences spatial distribution, 123 pinchpoints, 231 barriers, topographic gradient characteristics. Based data, proposed relevant policy opinions zoning control. results show incorporating trade-offs services into assessments can lead more effective selection sources. Meanwhile, constructed by using correct resistance surface truly reflect need under trend. research framework "ecosystem assessment incorporates - theory" could address technical issues constructing compound large regional/national regions key function areas.

The trade-off of ecosystem services should be considered in ecological security pattern (ESP) construction, which can reflected landscape multifunctionality and comprehensive importance. Multi-intensity ESPs management is also required to achieve effective planning. In this study, we proposed an approach multi-intensity construction that integrated multifunctional identification multi-criteria decision-making into source identification, categorized sources based on the "trend-status-risk" framework, with a case study city belt along Yellow River Ningxia. results showed optimal weights four habitat maintenance, water conservation, carbon sequestration soil retention decision making were 0.5000, 0.2071, 0.1589 0.1340, respectively. degree was 0.6612, overall conservation efficiency 1.5212. Conservation priority areas had overlapping area 2189.38 km2, accounting for 84.86% identified through multifunctionality. ESP included 45 covering total 6067.14 km2 91 corridors 3331.62 km2. aiming at prevention, restoration reconstruction established corresponding suggestions. constructing has application potential planning ecologically vulnerable regions, facilitating differentiated management.

As a crucial component of the ecological security pattern, source (ES) plays vital role in providing ecosystem service value (ESV) and conserving biodiversity. Previous studies have mostly considered ES only from either landscape change pattern or function perspectives, ignored their integration spatio-temporal evolutionary modeling. In this study, we proposed multi-perspective framework for characteristics by ESV incorporating aesthetics, carbon sink characteristics, quality, kernel NDVI (kNDVI). By integrating revised normalized difference vegetation index as foundation, employed spatial priority model to identify ES. This improvement aims yield more practical specific result. Applying Three-River Headwaters Region (TRHR), significant sources has been observed 2000 2020. performance provided reference conservation TRHR. The results indicate that identification reliable accuracy efficiency compared with existing NRs method could reveal precise distributions ES, enhancing integrity technical modeling support developing cross-scale planning management strategies nature reserve boundaries. our research serve building networks other ecologically fragile areas.

Rapid urbanization in the Jiangnan Water Network region has resulted degradation of ecosystems and interruption ecological functions. The security pattern (ESP) is crucial for balancing economic development protection within an area. In this study, we focused on a representative Gaochun water network area devised comprehensive ESP methodology. This study combined importance ecosystem services (ESI), landscape connectivity (Con), sensitivity (ESS), starting with analysis sources. Furthermore, both natural human factors are emphasized when constructing resilience surface. Nighttime lighting data (NTL), risk index (ERI), land intensity factor (CI) were used to calibrate resistance values. Finally, circuit theory was applied determine optimal path, width, strategy points corridors. results indicate We identified 39 source areas, 74 corridors, 33 pinch points, 45 barriers. Based this, overall spatial optimization plan “five cores, three patches, belts, multiple points” obtained. aimed explore optimize approach regional characteristics, providing new pathways decision support future construction patterns region.
