Abstract The abundance and quantity of waterbird species are often used to evaluate the ecological status wetlands because most waterbirds sensitive environment. Traditional methods detecting not only time-consuming but also inaccurate. Some investigations may even be at risk natural environment, E.g., bad weather or wild animal attacks. To address this issue, we designed an intelligent automatic identification system based on Model-View-Viewmodel (MVVM) framework which can support high effectively, safe long-time monitoring native wetland waterbirds. implement system, trained a model (WIM) using YOLOv5 algorithm deployed it back-end for real-time detections, identifications, recording counts different time intervals. It was integrated into WebGIS-based application, helpful user observe spatial distributions analyzing their changing laws. We employed PostgreSQL Database manage geospatial data corresponding access APIs. In addition, tool uploading labeling images online implemented pre-training, retraining, updating WIM. our current image plays vital role is auto-update, means that once users finished new image, pretrained WIM will updated automatically. Although still its initial testing phase, some results show works well. identifying rate recall reach 81.00% 99.00%, respectively. ongoing able meet basic requirements record maximum number observations within certain interval specified by users. And provide more information about managers better understand

Yancheng coastal wetland, as an important part of the East Asian–Australasian Flyway, provided habitat for more than 200 migratory waterbirds by rest and over-winter. After it was listed a “World Heritage List” in 2019, protection waterfowl wetland has attracted extensive attention from international community. As indicator species ecosystem health, have practical significance wetlands. Due to long-term impact human activities, waterbird habitats are facing threat fragmentation lose, posing serious challenge its survival diversity. Based on survey data obtained Gruiformes, Charadriiformes, Anseriformes during whole years 2017 2021, this paper used Maxent software modeling niches distributions, comprehensive evaluation method based fuzzy mathematics, Linkage Mapper model assess suitability distribution waterbirds, identify gaps potential biological corridors wetland. The results showed that anthropogenic disturbance were decisive factors affecting selection waterbirds. suitable 23868, 22670, 24870 ha, respectively. area 121,930 concentrated study area's central southern coast.

Coastal regions stand as pivotal zones of interaction between the marine and terrestrial environments, holding substantial significance for both ecosystems human societies. Since 1980s, China’s coastal (CCZ) have undergone rapid economic expansion, a surge in urban development activities, considerable population increase, instigating significant alterations land use along coast. However, recent years, studies regarding changes been notably scarce. Utilizing Comprehensive Lands Cover Database (CLCD) dataset, this study scrutinized spatiotemporal patterns Chinese coastline since 1985. It delved into temporal spatial variations use, ecological transformations, evolution intensity, examining these facets across provinces, municipalities, different distance bands from zone. The research findings indicated: Overall, cropland forest predominantly occupied zones, encompassing over 80% total area. Between 1985 2020, primary involved decrease an increase construction land, with reduction 5.97% cropland, largely transitioning (84927.21 km 2 ) (4218.55 ), resulting 5.98% land. Despite intensification development, exhibited initial rise followed by declining trend. There existed distinct disparities among provinces cities, prevailing all areas except Macau. Construction intensity witnessed increases, most Macau least pronouncedly Guangxi. Variations were considerable, Hebei Guangdong witnessing increases while other tended towards stability or reduction. Each band manifests unique pattern. Except 100-150 zone, demonstrates increasing trend bands. Ecological expanded initially but fluctuated further coastline. Land decreased initially, then stabilized, 0-10 zone showed highest intensity. Analyzing to 2020 can offer valuable insights management sustainable zones.

The ecological supply–demand mismatch resulting from rapid urbanization stands as a core challenge affecting regional sustainability. This study constructed networks the perspective of circulation processes flow within regions, and proposed novel relationships evaluation index system. case results six typical cities in 'Upstream-Midstream-Downstream' Yellow River Basin demonstrate that our system can more accurately reveal dynamic interaction resources urban area degree mismatch. Additionally, we found relationship upstream is better than midstream downstream cities, with exhibiting worst performance. Furthermore, over past 20 years, all have consistently deteriorated, maximum decline reaching 39.8 %. Social development factors driven imbalance changes resource allocation spatial connectivity between supply demand sides, serving key factor driving deterioration relationships. Lastly, this proposes partitioned protection strategy adaptable to both basin individual cities. holds significant importance for optimizing protecting ecosystems different watershed segments.

Coastal wetlands provide extensive ecological services for life on Earth but are facing rapid global disappearance influenced by human activities and climate change. From 1984 to 2018, approximately 28% of the natural coastal in China were lost due seawater intrusion, reduced sediment acquisition, urbanization, reclamation. Tiaozini wetland used be reclaimed during 2010-2019, quickly shifted conservation with less than 3 years. We analyzed years top-down eco-governance bottom-up Tiaozini, one typical wise use instead Collaboration stakeholders, such as management company, local residents, tourists, scientific committees, NGOs, media, facilitated a successvie way towards eco-governance, including public participation environmental education. Adaptive management, ecosystem-based natural-based solutions play very important roles from both approaches. Results showed that 3-year induced great achievements biodiversity ecotourism development, which outweighs 10-year reclamation exploitation.
