不同水位梯度下若尔盖高原湿地木里苔草株高生长特性

The Height Growth Characteristics of Zoige Plateau Wetland Carex Mulieensis in Different Water Level Gradient

以若尔盖高原湿地典型植物木里苔草为研究对象,设计了5个水位梯度:-5cm、-3.5cm、0cm、8cm、22cm,研究不同水位梯度下木里苔草株高变化规律.结果表明:生长季节结束时,木里苔草的株高随着水位的加深而增加,不同的水位梯度下株高的绝对增长速率和相对增长速率呈现出单峰变化或是随着生长季节的延续而逐渐变慢的特点.

The plant height change law of carex mulieensis under the different water levels was studied.The results showed that during the whole growing season,Carex mulieensis height growth increased as the water level increased,Carex mulieensis height growth increasement changed with the growing season continued.The absolute growth rate and relative growth rate of plant height under different water gradient showed a single peak change or decreased gradually.
