The construction of natural protected area (NPA) systems is an important initiative to protect biodiversity and maintain the health stability ecosystems. Qinghai-Tibet (QTA) has extremely high ecological value, NPAs in this account for more than half China. As human activities have intensified, increasing number research been conducted on region. However, assessment network QTA underexplored. This study assessed networks derived from NPA system a "quality-structure–function" perspective. First, used remote sensing index (RSEI) map resistance surface QTA, generated corridors based circuit theory, identified barriers pinch points evaluate quality network. Next, spatial syntax method was assess structural characteristics connectivity Finally, analysed changes activity intensity species population around quantitatively explore corridor's maintenance function context increased activity. findings demonstrated that within generally good. some areas such as Hung River Valley Qilian-Qinghai Lake were observed exhibit concerns, barrier points. These challenges stem competing interests environmental development utilization land. In terms indicators network, closeness eastern part higher western part; however, mean depth shows opposite pattern, indicating northeast better overall west. addition, footprint decreased continuously with distance over last two decades, noticeable increase occurred, magnitude grows experiencing mounting pressure due frequent activities. still play key role maintaining protecting environment. could provide scientific support eco-security shield functions globally.

With rapid urbanization and frequent disasters, regional ecosystem resilience decreased continuously. Strengthening the of ecological network is conducive to improving benefits quality products. The research on networks increasingly concerned, it necessary construct a comprehensive framework evaluate networks. Taking Wuhan metropolitan area as case, this aimed constructs an evaluates from perspective complex Firstly, we evaluation Index structure function dimensions. Secondly, regions with high importance are selected sources according landscape connectivity. Thirdly, MCR model used establish network. Finally, analyzed characteristics under different node failure scenarios. results show that: (1) Ecological nodes correspond wide variety land types, including forest, water bodies, croplands, urban build-up; (2) overall connection corridor relatively main components forest bodies; (3) trend structural functional does not always convergence shock simulation which related redundancy will help analyze provide references for optimization improvement sustainable management restoration.

Habitat fragmentation, a contributor to biodiversity degradation in urbanized regions, will result from rapid urbanization. Due the low quality of habitats and complexity land use high-density cities, traditional ecological corridor development approaches may not be viable for urban contexts. Furthermore, unlike other corridors, width corridors is fixed due very constrained high density structures areas. However, we discovered few studies on how build densely populated Aside that, earlier primarily concentrated identifying potential paths with spatial range typically being determined subjectively. The goal this research was develop an integrated approach determining suitable areas rapidly urbanizing region. Firstly, key species were identified Morphological Spatial Pattern Analysis (MSPA) applied identify core established city, which then NDVI InVEST construct resistance surfaces. Potential graded importance by Linkage Mapper. Finally, our metric indicators system, four set framework: animal migration, maximum cost-weighted distances animals can migrate, mobility potential, greatest restoration opportunities. A total 33 sources 63 identified. only 10 m wide at its narrowest point 100 widest point. Delimiting appropriate provide guidance implementation ensuring security

Implementing ecological conservation and restoration of territorial spaces is an effective way building civilization while maintaining national security in the new ear. However, there a need to identify priority areas for from perspective landscape connectivity ecosystem integrity. In Tianjin City, which highly urbanized city northern China, economic development threatens undermine environmental protection; therefore, its natural resources should be preserved degraded ecosystems restored. This study used morphological spatial pattern analysis (MSPA), assessment, circuit theory construct regional networks. Subsequently, were identified, including pinch points, barriers, breakpoints. The results showed that networks contained 2319.67 km2 sources dominated by woodlands, waters wetlands, comprising 71 corridors with total length 366.91 km coverage area 526.66 km2. distribution was closely related layout sources. included 31 80 Targeted strategies proposed comprehensively analyzing land-use status characteristics diverse areas. provides scientific guidelines formulating implementing planning identifying specific locations

The construction of ecological security patterns (ESPs) from the perspective ecosystem services is vital in regional sustainability. However, previous approaches have often not considered complex trade-offs between during ESPs. Taking Daning river basin karst areas southwest China as our study area, we improve current methodological framework to construct an ESP by integrating service trade-offs, typical characteristics and circuit theory. multi-criterion decision method ordered weighted averaging was used balance determine sources with optimum conservation efficiency. resistance surface based on land use modified nighttime light intensity rocky desertification index. Circuit theory then applied identify corridors, pinch points barriers. results showed that spatial six (food provision, carbon sequestration, soil retention, water yield, habitat quality recreation) varied considerably within area. By comparing efficiencies, scenario 5 selected optimal scenario, efficiencies were > 1 more balanced, illustrating flexibility feasibility method. comprehensively reflected dual influence human activity ecosystems. included 34 sources, 66 key corridors area 957 km2, 100 36 barriers distributed corridors. mostly covered forest mainly north east densely located south central areas, where also concentrated. Barriers edge Based ESP, divided into ecologically important northern eastern improving southern, corresponding restoration measures proposed. In summary, this makes up for shortcomings constructing ESPs simple overlaying services. Our findings could effectively enhance robustness sustainability areas.
