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.

Mitigating ecosystem degradation has been a worldwide strategy, and China implementing land spatial ecological restoration for an all-around preservation in recent years. A comprehensive diagnosis of the health status effective division zoning are essential to formulating strategies at regional scale. Here, index (EHI) was computed years 2010 2020 using vigor-organization-resilience model. Then, three-step statistic-based, continuity-based, practice-based (SSP) framework developed classify zones with consideration status, relation, local practices. We applied integrated approach urban agglomeration middle reaches Yangtze River (UAMRYR) as study area. The results showed that: (1) EHI had slight decreasing trend from 2020, distribution pattern healthy, unhealthy, healthy center periphery UAMRYR. (2) Eight were designated adjusted through SSP framwork be space-full practical. Zone VIII accounted largest proportion (41.12%), followed by Ⅰ (21.57%). (3) Finally, corresponding proposed each zone. This contributes differentiated UAMRYR, shedding light on regulation Sustainable Development Goals achievement global regions complicated environmental problems.

In China, the Huang-Huai Plain and middle reaches of Yangtze River, which are populated with numerous small medium-sized cities, have emerged as critical regions for future urbanization. As a result, these face significant ecological risks due to this rapid This study employs concept security pattern (ESP), synergizes landscape patterns processes by emphasizing connectivity. integration facilitates balance between ecosystem protection economic development. Utilizing Suizhou case study, framework establishing an ESP in rapidly urbanizing cities is proposed, aim addressing challenges posed A principal component involves optimizing identification sources. The ordered weighted average (OWA) method was used accurately pinpoint areas services while considering necessary trade-offs. Furthermore, sensitivity connectivity were integrated identify Subsequently, corridors, totaling area 416.08 km2 length 211.43 km, delineated using circuit theory.

The Yellow River Delta (YRD), a critical economic zone along China's eastern coast, also functions as vital ecological reserve in the lower River. Amidst rapid industrialization and urbanization, region has witnessed significant land use/cover changes (LUCC), impacting ecosystem services (ES) security patterns (ESP). Investigating LUCC's effects on ES ESP YRD is crucial for sustainable development. This study utilized PLUS model to simulate 2030 use scenarios, including natural development (NDS), (EDS), protection scenarios (EPS). Subsequently, InVEST circuit theory were applied assess under varying LUCC from 2010 2030. Findings indicate: (1) Notable 2030, marked by decreasing cropland increasing construction water bodies. (2) From 2020, improvements observed carbon storage, yield, soil retention, habitat quality, whereas 2020–2030 saw increases yield retention but declines quality storage. Among EPS showed superior performance all four ES. (3) Between sources, corridors, pinchpoints expanded, displaying spatial heterogeneity. scenario yielded most substantial pinchpoints, totaling 582.89 km2, 645.03 64.43 respectively. highlights importance of EPS, offering insightful scientific guidance YRD's

Under the dual influence of climate change and human activities, structure function Qinghai-Tibet Plateau ecosystem have undergone profound changes, its ecological security has been a frequent focus academic attention. The calculation bottom line (ESBL) is an essential step in study security. However, current ESBL ecologically fragile areas (QTPEFA) carried out only from perspective supply, research demand largely ignored. Therefore, taking Qinghai Province as case, this paper exploratively calculated supply combination with food standards. Simulation future trends land-use service value (ESV) evolution based on GeoSOS-FLUS under four scenarios, i.e., natural development (ND), protection (EP), cultivated land (CLP) (DP), we explored which measures move ESV closer to (DESBL) provide reasonable suggestions for eco-protection policies. results showed that: (1) overall continuous increase during period, but led different degrees loss. (2) both were 6003.41 hundred million 13132.46 million, respectively. At present, actual higher than (SESBL) far below DESBL. (3) DP scenario was closest DESBL provided relatively more food. most conducive balancing Province. This provides new paradigm measuring scientific basis optimizing policies QTPEFA by comparing multi-scenario simulation line.
