Introduction: Wetland has been exposed to tremendous stresses and hazards, leading many potential ecological risks in the past few decades. There is an urgent need assess risk status of wetland, especially when examining how intensity socio-economic growth, policy changes, other variables affect land use changes. Methods: This study models LULC pattern Liaohe Estuary National Nature Reserve under various future scenarios 2000–2040 develops a long-term Pressure-State-Response assessment model based on characteristics northern wetland environment China, combined with simulated multi-scenario PLUS model. Results: As two most distinct vegetation types reserve area, Phragmites australis Suaeda glauca presented decreasing trends 59.7 ha/year 9.0 economy development scenario (EDS), higher than 57.3 ha/year, 8.2 natural increase (NIS), 35.4 5.8 protect (EPS). From core area buffer outer experimental slope rate deterioration rises severely. In comparison EDS, aquiculture oil wells can be lowered by 11.4 1.1 application protection measures. Besides, three scenarios, mean are all showing increasing trend from 2000 2040, which generally EDS that NIS EPS scenarios. The proportion high very level continually increased 28.8% 40.4% was mainly located south estuary west urban areas. addition, among protected areas, lower growth zone zone. Discussion: Aiming for Park, these findings provide quantitative guidance protecting restoring resources.

Wetlands are badly damaged in many parts of the world. The wetland management Minjiang Estuary has achieved remarkable results. This provides valuable experience for other areas. can achieve effect, mainly because adoption water quality management, ecological restoration, and tourism development. However, different modes have their own scope application. In order to spread its successes, three differential game related constructed, equilibrium results compared analyzed. Finally, research shows that amount control by governments is directly proportional resilience wetlands. social organization culture degree better quality. development government organizations decrease investment spontaneous industry. When loss caused flood or restoration effect large, should adopt mode. increased income reputation ecotourism mode be adopted. a reference how manage wetlands promote areas more effectively.

Wetland vegetation is the basis for wetland ecosystems to regulate climate change, carbon sequestration and maintain biodiversity. Therefore, high-precision mapping dynamic monitoring of are essential effective management, restoration sustainable development ecosystems. This study addressed explore classification performance backscattering coefficients polarimetric decomposition parameters multi-frequency SAR images, including single-polarimetric X-band TerraSAR (TS), full-polarimetric C-band Radarsat-2 (RS) L-band ALOS PALSAR-2 (PS) marsh in Honghe National Nature Reserve, Northeast China. We proposed two transfer-learning strategies, examined feasibility classifications between optical sensors, different frequencies (X-, C- L-band) its derivative respectively. paper further compared from parameter images coefficient under same sensors. The results indicated that: (1) three performed good ability identifying with overall accuracies (OA) ranging 0.74 0.88. For frequency outperformed an OA improvement 0.24 % 2.41 %; (2) longer wavelength produced better results, PS realized highest accuracy (OA = 0.871); (3) Full-polarimetric obtained > 0.8), frequencies; (4) transfer learning sensors that images. this provide a scientific change conservation development.

Background and objectives: Land use land cover change (LULCC) directly affects the human living environment economic society by influencing ecosystem services. This study explores complex relationship between LULCC services in Dongting Lake region of China. Methods: The analysis incorporates transfer matrix LULCC, service value (ESV) accounting, Mann–Kendall mutation test, gray correlation, path analysis. explored spatial temporal characteristics revealed comprehensive impacts on from perspective factor interactions. Findings: findings reveal that open water (OW) area farmable are dominant types transferring out area, with significant interconversion observed among wetland (WL), arable (AL), forest (FL). Water conservation, waste disposal, climate regulation, biodiversity conservation emerge as most crucial area. identifies consistent patterns abrupt changes ESV across six analyzed time periods. Forest exhibits substantial direct influence gas exchange, soil formation protection, biodiversity, raw materials, recreation leisure. Additionally, land, wetland, contribute significantly to total ESV, being differentiation region. Conclusion: research reveals consistency trends is a process influenced multiple factors, which conversion ecological non-ecological has impact, coupling coordination drivers together Furthermore, alters structure scale ecosystems, resulting alterations ESV.
