摘要

As an important wetland with international significance in biodiversity conservation, Poyang Lake is under severe pressure from increasing human activities, such as prescribed fire. In this study, a fire-prone plant community (Triarrhena lutarioriparia L. Liou) was selected in Poyang lake, and a 5-year study on annual prescribed fire and corresponding monitoring were conducted in this representative plant community. Results showed that sprout density, plant height and biomass of burn samples were significantly higher than those of the control. However, burn samples presented significantly lower values of species richness and community biodiversity in the later period. Furthermore, periodical fire significantly promoted the availability of nitrogen and phosphorous in surface soil, which were closely and positively related to height, dominance and biomass of T. lutarioriparia.. Considering the positive influences on the plant traits and species composition, prescribed fire could potentially be used as an effective means to maintain the ecological health of Poyang Lake.

Liou），并对该代表性植物群落进行了为期5年的年度明火研究和相应的监测。结果表明，烧伤样品的发芽密度，株高和生物量均显着高于对照。但是，在后期，烧伤样本呈现出的物种丰富度和社区生物多样性的价值明显较低。此外，周期性的火势显着促进了表层土壤中氮和磷的有效性，而氮和磷的高低与黄粉height的高度，优势和生物量密切相关。.考虑到对植物性状和物种组成的积极影响，明火可能作为维持Po阳湖生态健康的有效手段。
