Analysis of Wetland Landscape Pattern and Study on Pattern Stability Based on Type Level
The stability analysis of the landscape pattern in wetland nature reserves is essential for protecting natural resources and achieving sustainable development.In this article,taken the Huihe Wetland Nature Reserve as the research area,and used methods such as pattern index determination stability model and MCCA model,the landscape pattern and pattern stability of the Huihe Wetland based on type level is analyzed,and the future pattern stability is predicted.The results indicate that from 2000 to 2020,the dominant types of landscape pattern in the Huihe Wetland Nature Reserve were swamp wetlands and grassland types,with an increase in fragmentation degree and greater than other types.Patches are less affected by human interference,have high and stable aggregation,and have greater connectivity with other types of patches.(2)Landscape pattern stability from 2000 to 2020:grassland＞swamp wetland＞sandy land＞lake＞forest land＞urban construction land.(3)The landscape pattern in 2030 will still be dominated by marsh wetlands and grassland landscapes,and the stability of each type of pattern is consistent with that of 2000～2020.
