摘要
黄河三角洲位于山东省东北部。本地区自然植被的主要类型是盐生草甸,其中广泛分布在低平洼地、黄河故道以及池塘河渠的芦苇(Phragmites communis)种群是该地区重要的农业资源之一。通过在生长季中对这一种群的定位研究,初步揭示了种群高度和地上净生产量动态的基本规律。一。
The height growth of Phragmites communis population conforms to the Jaw of reciprocal equation, which reduces gradually during growing seasons. The dynamics of population height growth is significantly positively correlated with effective accumulated temperature of environment and negatively correlated with accumulated precipitation. The variation of net aboveground production conforms to the Logistic model, which is significantly positively correlated with effective accumulated temperature. The dynamics of population height and net aboveground production reflects the integrated interactions between individual development rhythm in population and environmental factors.
