To better conserve the ecology of the wild range, we studied the rhizosphere microenvironment of in Beijing's Yunmeng Mountain National Forest Park. rhizosphere soil physicochemical properties and enzyme activities changed significantly with temporal and elevational gradients. The correlations between soil water content (SWC), electrical conductivity (EC), organic matter content (OM), total nitrogen content (TN), catalase activity (CAT), sucrose-converting enzyme activity (INV), and urease activity (URE) were significant and positive in the flowering and deciduous periods. The alpha diversity of the rhizosphere bacterial community was significantly higher in the flowering period than in the deciduous period, and the effect of elevation was insignificant. The diversity of the rhizosphere bacterial community changed significantly with the change in the growing period. A network analysis of the correlations revealed stronger linkages between the rhizosphere bacterial communities in the deciduous period than in the flowering period. was the dominant genus in both periods, but its relative abundance decreased in the deciduous period. Changes in the relative abundance of may be the main factor influencing the changes in the rhizosphere bacterial community. Moreover, the rhizosphere bacterial community and soil characteristics were significantly correlated. Additionally, the influence of soil physicochemical properties on the rhizosphere bacterial community was larger than that of enzyme activity on the bacterial community. We mainly analyzed the change patterns in the rhizosphere soil properties and rhizosphere bacterial diversity of during temporal and spatial variation, laying the foundation for further understanding of the ecology of wild .
为了更好地保护野生[植物名称]的生态环境，我们对北京云蒙山国家森林公园内[植物名称]的根际微环境进行了研究。根际土壤理化性质和酶活性随时间和海拔梯度发生了显著变化。在开花期和落叶期，土壤含水量（SWC）、电导率（EC）、有机质含量（OM）、全氮含量（TN）、过氧化氢酶活性（CAT）、蔗糖转化酶活性（INV）和脲酶活性（URE）之间的相关性显著且为正。根际细菌群落的α多样性在开花期显著高于落叶期，海拔的影响不显著。根际细菌群落的多样性随生长时期的变化而显著改变。相关性网络分析表明，落叶期根际细菌群落之间的联系比开花期更强。[优势菌属名称]在两个时期都是优势属，但在落叶期其相对丰度下降。[优势菌属名称]相对丰度的变化可能是影响[植物名称]根际细菌群落变化的主要因素。此外，[植物名称]根际细菌群落与土壤特性显著相关。此外，土壤理化性质对根际细菌群落的影响大于酶活性对细菌群落的影响。我们主要分析了[植物名称]根际土壤性质和根际细菌多样性在时间和空间变化过程中的变化模式，为进一步了解野生[植物名称]的生态学奠定了基础。
