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.

Building an ecological security pattern (ESP) can safeguard and improve the structure, functions services of regional ecosystems. Furthermore, it is also one significant spatial methods to mitigate conflict between conservation economic growth. Most previous researches on construction ESP have directly utilized extensive regions forestland, grassland, water area or nature reserves as sources (ESs) without weighing habitat quality (HQ) protection red line (EPRL). The ES Dawen River basin (DRB) was identified through morphological analysis (MSPA) landscape connectivity index. By employing minimum cumulative resistance model (MCR), potential corridor (EC) identified, its importance evaluated by gravity model. Simultaneously, properties HQ (ER) were analyzed. Finally, this paper proposed optimization strategy for in accordance with EPRL. results indicate that: (1) DRB contained 15 important ESs, mainly concentrated mountain forest areas. (2) 105 ECs extracted MCR model, including 35 level 1 corridors 70 2 corridors, which primarily eastern region basin. (3) Based characteristics ER, well EPRL research, "one axis, two belts five zones" constructed control strategies proposed.

Limited attention has been given to improving carbon storage by identifying ecological conservation and restoration areas (ECRAs). In this research, we proposed a new framework for ECRAs incorporating future changes into security patterns (ESPs), including several models of the Patch-generating Land Use Simulation (PLUS), Integrated Valuation Ecosystem Service Tradeoffs (InVEST), Minimum Cumulative Resistance (MCR) circuit theory. This was applied in Jiangsu Yangtze River Economic Belt, East China. To evaluate effectiveness framework, compared two scenarios: an priority scenario (EPS) where change not considered ecosystem sequestration (ECSS) explicitly incorporated. Under EPS, were 11169.87 km2 221.11 km2, respectively. ECSS, 14768.76 244.89 Carbon will be most likely increase around lakes River, identified key under ECSS more adaptable environmental than EPS. can effectively enhance both function sequestration, providing effective support policymakers landscape management low-carbon development other regions facing similar challenges. meantime, caution is needed possible limitations, such as without adequate consideration uncertainties population, land use, economy future.
