Abstract Starting from the overall pattern of wetland evolution in Yellow River Delta, combination CA–Markov model and MLP is studied. Based on low-medium resolution Landsat data field survey data, trend landscape Delta simulated predicted by using proposed models. Taking high (2 m) 2016 as precision verification, simulation results are validated. The show that area natural wetlands was decreas...

River deltas are formed by the interaction of connecting water and sediment, they among most economically ecologically valuable ecosystems on Earth. Because their special locations, together with direct indirect human interference, river expected to be more vulnerable fragmented. The increasing fragmentation is largely due longitudinal hydrological connectivity disruption caused activities. How...

Studies on the ecosystem service value (ESV) of gardens are critical for informing evidence-based land management practices based an understanding local ecosystem. By analyzing equivalent factors (EVFs), this paper evaluated values 11 services in Yellow River Basin China 2019. High-precision use survey data were used to improve accuracy classification, garden areas, and spatial distribution ESV...
