To conserve bird biodiversity and monitor the distribution of species in region, it is tremendous necessity to identify birds by their songs explore rich ecological information birdsong contains. The audios recorded monitoring area generally have complex background noise, characteristics song are not prominent biological spectrum comprehensive, which brings some challenges identification birds. This study proposes a hierarchical feature extraction architecture combining dynamic static modeling cope with environments as context. Firstly, six common speech features were extracted for birdsong. Pearson correlation coefficient then used analyze correlations between human speech, examining each presence absence environmental noise interference. Combined scatter plot matrix analysis, we conclude that Mel Frequency Cepstral Coefficient (MFCC) more suitable comparing other when dealing can superiorly noise. Secondly, built, integrates fully contextual relationship, solve problem ignoring internal structure patch losing spatial Transformer-type model. Finally, refinement module designed help extract detailed features, well optimize computational cost model requires many training data has high complexity. performance be detected 93.67 % accuracy on self-built dataset, 95.19 public dataset Birdsdata 97.02 UrbanSound8k.

Rapid urbanization and people's growing spiritual demand make urban spaces face the problem of green space allocation, especially mismatch between supply cultural ecosystem services (CES). The matching degree CESs is significantly related to well-being residents. However, few existing studies have compared CES from perspective old new districts. This study constructed a theoretical framework oriented four functions (aesthetic appreciation, recreation leisure, educational opportunities, history culture) based on subjective objective evaluation spatial autocorrelation analysis in order map supply–demand pattern parks at community scale. Qinhuai district Nanjing, where division districts relatively obvious, used as area explore influence balance. Results showed that: (1) had high agglomeration characteristics, service capacity decreased radially centered large medium-sized comprehensive parks; (2) took an obvious trend gradual decrease northwest southeast, with heterogeneity; (3) mismatches were found scale, overall was better than These findings can provide valuable exploration for optimizing park configuration improving efficiency under background stock planning.

The ecological sustainability of arid and semi-arid areas is under increasing threat due to global climate change, well-established networks are essential for improving landscape connectivity conserving biodiversity. This study takes the Tacheng-Emin Basin in China as an example. Based on "source-resistance-corridor" research paradigm sustainable development theory, "contribution-organization-vitality-resilience" circuit theory ecosystem incorporated into construction networks. results show that (1) service value basin 5.85 × 1010 Yuan, medium health level, security hierarchy has low level uncoordinated problems. (2) total integrated resistance surface dominated by natural resistance, characterized evident fragmentation. (3) 25 sources, 58 corridors, 32 stepping stones, 39 obstacle points, 46 fracture points were extracted at threshold 10,000 model.

Abstract Adaptive management is an approach for stewardship of social–ecological systems in circumstances with high uncertainty and controllability. Although they are largely overlooked adaptive (and system management), it important to account spatial temporal scales mediate within- cross-scale effects actions, because interactions increase can lead undesirable consequences.

Resource, environmental, and ecological issues have become major constraints to the development of many regions. The Yellow River Basin is an important barrier for maintaining security in northern China, but it has been impacted by problems such as severe soil erosion declining biodiversity. rational construction patterns enhance ecosystem functions maintain regional security. In this study, a comprehensive assessment system was constructed selecting service importance, sensitivity, landscape connectivity assess Xiliu Ditch, ecologically fragile region Inner Mongolia section China. results showed significant spatial heterogeneity, with medium- low-security value areas dominating, while high-security accounted only 18.7% study area. Seventeen sources were identified from areas, which mainly composed grassland, woodland, water bodies, most are distributed southern part Twenty corridors selected minimum cumulative resistance model gravity classified into 15 5 potential corridors. Forty-six nodes defined, including twenty strategic points, nine seventeen break points. On basis, we pattern “two belts, three cores, six zones, multiple nodes” proposed corresponding governance measures. This explores at small watershed scale, helps realize fine management Ditch basin and, on can provide scientific support protection sustainable basin. addition, new ideas similar around globe.

The protection and sustainable management of cultivated land are cornerstones ensuring ecological balance. In implementing policies, spatially defined land-use strategies can aid in the utilization these resources. Yet, recent agricultural activities have affected water quality Yellow River pose a significant challenge to basin. Many policy considerations overlooked ecosystem integrity. To address this oversight, we targeted cities bordering main course Henan Province constructed an security pattern (ESP) by "five zones, one belt, multiple corridors, points" coordinated development use protection. Ecological sources were identified via four services (ESs) ordered weighted average (OWA) method. ESP was built using minimum cumulative resistance (MCR) model circuit theory, while natural scenarios simulated FLUS model. results showed that scene under restriction (ESPR-CP) beneficial environment. Prior enacting measures, developments within priority conservation areas should be restricted.

ABSTRACT Anthropogenic interference causes ecological fragmentation and vulnerability, weakening urban ecosystems' adaptive capacity. The network is based on the principles of landscape ecology, connecting resource patches through linear corridors to protect biodiversity integrity, enhance environmental carrying capacity, improve ecosystem resilience. However, current research resilience often relies single methods scales, overlooking potential discrepancies between different approaches scales. This study uses Zhejiang construct networks with structural, functional, integrated at provincial, agglomeration, city levels. performance these in protecting structure, maintaining function, ensuring overall was compared, yielding following results: First, spatial output consistency source areas across scales for three ranged from 50.48% 97.81%. Second, approach not optimal all goals. structure‐oriented method demonstrated cross‐scale applicability structural goal, while function‐oriented strategy performed well functional Third, scale analysis showed results provincial agglomeration levels when meeting same objectives, but level.
