北京怀九河河岸类型的植被与土壤理化性质差异
Vegetation and soil physicochemical properties in different types of the Huaijiu River riparian in Beijing
摘要
Abstract
[Background] As an important component of riparian ecosystem,vegetation and soil are closely related to the biodiversity,stability,nutrient filter in riparian.To date,however,there are few studies about the spatial variation of the riparian vegetation communities and soil physicochemical properties under different types of riparian.[Methods] The study was carried out in the Huaijiu River,southwest of Huairou district,Beijing.According to the extent of disturbance and development status of riparian zones,we divided it into three types (natural type,near-natural type,and artificial type).Then,based on the survey of 15 natural type plots,25 near-natural type plots and 20 artificial type plots,we investigated the vegetation diversity and the soil physicochemical properties and compared them between different riparian types.[Results] Vegetation diversity and soil physicochemical characteristics were significantly different in different types of riparian.The vegetation composition in the riparian of the Huaijiu River was mainly herbs,accounting for 79.22％ of the total number of species,and of species diversity (4.6 ±0.16) and species richness index (7.26 ±0.40) of the natural type riparian was greater than the near-natural type (3.82 ±0.16 and 6.36 ±0.32) and the artificial type (3.94 ±0.18 and 5.40 ±0.42) (P ＜ 0.05);The soil quality showed a degradation trend with increasing magnitude of disturbances.The soil organic matter content of the natural riparian (4.88 ± 0.43％) was higher than the near-natural riparian (3.47 ±0.31％) and artificial riparian (1.92 ±0.15％) (P ＜0.05).The soil bulk density of the natural type was lower (1.18 ± 0.03 g/cm3) than near-natural riparian (1.35 ± 0.03 g/cm3),and the soil bulk density of artificial riparian was the highest,which was matter content (P ＜0.05),while the richness index was negatively correlated with soil bulk density (P ＜ 0.01) and positively correlated with soil total porosity (P ＜ 0.05).[Conculsions] The results showed that the correlation relationship between vegetation and soil was influenced by human disturbances.It provides a theoretical basis for the restoration and reconstruction of riparian ecosystem in Beijing mountain area.关键词
