陕西黄河湿地芦苇的生长特性及生物量动态

本文以陕西黄河湿地芦苇为研究对象，采用样本调查法研究了芦苇的生长指标及地上部分生物量动态，了解环境因素的改变对陕西黄河湿地芦苇的生长情况影响。结果表明：陕西黄河湿地芦苇平均株高102.3119.22cm、平均茎粗2.180.49cm、平均单株叶面积66.5816.09cm2、单株平均展开叶片数为4.670.99、叶平均生物量为1.240.51g/m2、茎平均生物量为3.251.74g/m2、地上平均生物量为4.492.03g/m2。各项生物指标都与芦苇生长规律相符合，表明陕西黄河湿地芦苇的生长状态良好。

Study on the Growth Characteristics and Biomass Dynamics of Reeds in the Yellow River Wetland in Shaanxi Province

The reeds of the Yellow River wetland in Shaanxi are the research object in this experiment, the growth index of reeds and the biomass dynamics on the ground were studied by using the sample survey method to understand the growth of reeds in the Yellow River wetland by environmental factors. The results showed: the Yellow River wetland reed, average plant height is 102.31 19.22 cm, an average of 2.18 0.49 cm thick stems, and an average of 66.58 16.09 cm2 per plant leaf area, and average on leaf number per plant was 4.67 0.99, average leaf biomass was 1.24 0.51 g/m2, biomass of stems was 3.25 1.74 g/m2, ground biomass of 4.49 2.03 g/m2. The biological indicators are consistent with the growth pattern of reeds, indicating that the reeds of the Yellow River wetland in shaanxi province are highly adaptable and growing well.
