Abstract:In order to clarify the landscape pattern characteristics of Changjiang Haiwei Wetland, explore its influencing factorsand better protect and utilize this wetland, the landscape pattern of Changjiang Haiwei Wetland from 2014 to 2024 is analyzed through the analysis of the dynamic change of land use, the analysis of the landscape pattern index as well as the on-site survey, and the driving factors of wetland landscape pattern characteristics are explored with the combination of the natural, humanistic and other factors. The results of the study show that the areas of wetland plants, construction land, bare land and roads in Changjiang Haiwei Wetland have decreased over the past decade, with construction land showing the most significant decline, while woodland, grassland, and water areas have increased. At the typological level, the dominant landscape type in the Changjiang Hawei Wetland is woodland. The landscape is becoming increasingly fragmented, with the shapes of various patches tending to become more complex, and the overall aggregation degree is on a downward trend, with a significant decrease in the aggregation degree of wetland plants. The main factors influencing the evolution of the landscape pattern in the Changjiang Hawei Wetland are socio-economic factors, including population size and the tertiary industry, while environmental factors also play a certain role. Based on these findings, it is recommended to rationally plan the regional road landscape, emphasize the overall protection of the landscapes, enhance the protection of marshy wetlands as well as rare and endangered plants species.
