黄河坝下湿地不同景观类型植被演变特征及驱动力
Study on the Evolution Characteristics and Driving Forces of Vegetation in Different Landscape Types of the Wetland Below the Yellow River Dam
摘要
Abstract
To understand the evolution of vegetation community characteristics and driving forces in different land-scape types,the evolvement rule of the growth and diversity characteristics of vegetation communities in different landscape types of the Jili Yellow River Wetland downstream of the Xixia Yuan Dam in the middle reaches of the Yellow River were studied.Through on-site investigation,remote sensing image interpretation,and constructing aboveground biomass inversion model of herbaceous vegetation based on random forest,the growth characteristics and diversity characteristics of vegetation communities in different landscape types were analyzed,and the driving effects of environmental factors on the evolution of vegetation community characteristics in different landscape types were identified.The results showed that the vegetation coverage grade in the study area was mainly high vegetation coverage,followed by relatively high vegetation coverage.The average aboveground biomass of herbaceous vegeta-tion was generally in the low and medium plant zones,and showed a trend of increase-decrease-increase from 2018 to 2023,reaching the maximum and minimum values in 2019 and 2022,respectively,with 331 g·m-2 and 244 g·m-2.The vegetation in the tidal flat wetland showed the characteristics of coexistence of hygrophytes,meso-phytes and halophytes.Soil nutrient factors had a significant correlation with the intra-annual characteristics chan-ges of the vegetation communities in tidal flat wetland.While the land use types changes had a significant impact on vegetation coverage,especially in the areas with medium and low vegetation coverage that were more significantly.关键词
