As the core technology of artificial intelligence, salient object detection (SOD) is an important approach to improve analysis efficiency remote sensing images by intelligently identifying key areas in images. However, existing methods that rely on a single strategy, convolution or Transformer, exhibit certain limitations complex scenarios. Therefore, we developed Dual-Stream Feature Collaboration Perception Network (DCPNet) enable collaborative work and feature complementation Transformer CNN. First, adopted dual-branch extractor with strong local bias long-range dependence characteristics perform multi-scale extraction from Then, presented Multi-path Complementary-aware Interaction Module (MCIM) refine fuse representations targets global branches, achieving fine-grained fusion interactive alignment features. Finally, proposed Weighting Balance (FWBM) balance features, preventing model overemphasizing information at expense details inadequately mining cues due excessive focus information. Extensive experiments EORSSD ORSSD datasets demonstrated DCPNet outperformed current 19 state-of-the-art methods.

Net primary productivity (NPP) is a core ecological indicator within terrestrial ecosystems, representing the potential of vegetation growth to offset anthropogenic carbon emissions. Thus, assessing NPP in given region crucial for promoting regional restoration and sustainable development. This study utilized CASA model GEE calculate annual average Shandong Province (2001–2020). Through trend analysis, Moran’s Index, PLS−SEM, spatiotemporal evolution driving factors were explored. The results show that: (1) From 2001 2020, showed an overall increasing trend, rising from 254.96 322.49 g C·m⁻2/year. shift was accompanied by gradual eastward movement centroid, indicating significant spatial changes productivity.

In addressing global climate change and promoting economic growth, achieving a comprehensive carbon balance at the county level is vital for sustainable development. However, most studies focus on between emissions sequestration (CESB), neglecting intricate ecological (EECB) this scale. This study introduces an analytical framework that couples development with protection by using coupling coordination degree analysis, zoning, Markov-PLUS model. Taking Jiangxi Province as case study, we evaluate spatio-temporal dynamics of from 2000–2020 predict future trends 2030 under four potential scenarios. Results reveal significant regional variations in CESB over two decades, which primarily exhibit net emission. Meanwhile, continuous decline EECB highlights need balanced By 2030, land use's capacity expected to increase different scenarios, leading 'middle-high, sides-low' spatial pattern CESB.

With global climate change and irrational human activities, regional water resource conflicts are becoming more pronounced. The availability of in watersheds can be indicated by the yield. Exploring factors that influence yield is crucial responding to protecting resource. Previous research on influencing has frequently adopted a macro-level perspective, which failed reflect mechanisms changes at local scale adequately. Therefore, this study proposes novel framework for integrally evaluating impacts activities services from both perspectives. Taking Ganzhou City, source Ganjiang River, as an example, results show following: (1) City had largest 1307.29 mm 2016, lowest was only 375.32 2011. spatial distribution pattern mainly affected surface environment, high-value regions area were predominantly located urban areas with flat terrain. (2) At scale, where contribute than 80% accounted 25% area. In comparison, impact 0.95%. contribution rate significantly greater change.
