Therefore, exploring how protect optimize species' achieve harmony between humans nature is particularly important. As a paradise for wildlife, Poyang Lake habitat breeding ground birds, fish, other aquatic organisms. In this study, adopting multi-level perspective 'point-line-area', we had an appliance conservation by constructing ecological security pattern (ESP) in Ecoregion (PYLE). We produced land use cover from 2000 2040 using random forest cellular automata-Markov model. Combining morphological spatial analysis, landscape index, Linkage Mapper, constructed long-term ESP PYLE considering protection. spatiotemporal dynamics were compared analyzed. results show that PYLE's rapid economic led extensive urban growth, encroaching on surrounding bare land, which could undermine local survival. Based predicted 2040, propose optimized 'one area, two zones, multiple points' scheme prioritize This comprehensive study provides innovative ideas novel insights future research policy formulation

Ecological security pattern (ESP) represents a sound spatial arrangement of ecosystem occurring in landscape. The research on the optimization ESP aims to improve and restore functions by rationally allocating optimizing ecological elements based key issues. Constructing can enhance connectivity regional habitat patches, which is great significance for protecting restoring biodiversity, improving stability resilience, achieving sustainable development. However, it challenging task systematically resilience networks under attacks. Little has been done enhancing edge-based Based morphological analysis (MSPA), minimum cumulative resistance (MCR) greedy algorithm (GA) models, this study presents new method construct optimize ESP. Dongting Lake Basin China, typical region with rich complex landscape patterns, intensive human activities, taken as an example. results indicate that network improved its 51.62%, robustness against random attacks 41.13%, targeted 43.41%, relative initial network. Monte Carlo test verifies reliability solution. proposed be used finding structure best specific attacks, provides valuable decision-making reference land planning biodiversity conservation.

It is imperative to expand perspective encompass holistic resilience of thus safeguarding ecologically that play roles throughout entire network. Therefore, this study takes Nanjing City case establishes comprehensive EN assessment framework based on theory complex theory, grounded in foundation multidimensional indicators. Building upon this, research develops ‘regional simulation - spatial analysis identification’ investigative framework. The results show core structure centered around green spaces, rivers, lakes, similar features has taken shape, encompassing total 39 69 corridors. Examining from six perspectives, connectivity, integration, complexity, centrality, efficiency, substitutability, their integrated assessment, analyzed impact single sequential failures different component spaces overall EN. aimed identify space significantly contributes network's resilience. As result, was divided into three levels. source areas 1, 2, 7, 34, along with 1–34, 1–4, 4–11, 19–34, 18–19, 27–39, emerge primary region.
