[Objective] The landscape pattern and its vulnerability of urban wetland were investigated in order to provide a scientific basis for urban wetland protection and sustainable development.[Methods] Based on the high-resolution WorldView-3 remote sensing images, the distribution information of landscape types was extracted, and the landscape spatial structure indicators including landscape diversity index, patch density and number of patches were selected, and the spatial pattern and heterogeneity of landscape composition as well as the landscape vulnerability were evaluated by using geographic information system technology and theory of landscape ecology in the Datong wetland of Huainan City in Anhui Province. Based on the landscape sensitivity and fitness indexes, the landscape vulnerability assessment model was constructed to evaluate the landscape vulnerability of Datong urban wetlands.[Results] ① The landscapes in Datong wetland with balanced area scale were dominated by arbor, water, and bare land. ② The landscapes were interlaced in space and formed a distinct "network structure", among which, the water, bare land, and Metasequoia glyptostroboides were continuously distributed, while the others were highly fragmented and heterogeneous. ③ The vulnerability of landscape pattern was dominated by low vulnerability, showing significant positive spatial autocorrelation and spatial aggregation pattern. The main "high-high" value aggregation areas and vulnerability hot spots were mainly distributed in eastern bare land. The "low-low" value agglomeration area and vulnerability cold spots were mainly distributed in the water body area. ④ Landscape vulnerability was consistent with vegetation coverage and landscape pattern complexity, that was, the higher the vegetation coverage and the greater the interlace of spatial distribution, the less vulnerable it was.[Conclusion] The landscape types in the Datong wetland mainly include arbor, water bodies, and bare land. The vulnerability of the landscape is mainly low, and shows a significant spatial agglomeration pattern. It has spatial consistency with the vegetation coverage and the complexity of the landscape pattern.
