中文摘要	为了研究自然状态下半干旱地区湿地芦苇（Phragmites australis）种群生态特征的季节性动态变化以及水分变化对芦苇种群生态特征的影响，基于2007年5～10月莫莫格国家级自然保护区湿地芦苇种群特征以及地表淹水情况的监测资料，分析了该区芦苇种群的盖度、高度、密度和地上生物量等生态特征的季节变化。在此基础上，进一步分析了水位变化对芦苇种群生态特征的影响。结果表明：芦苇种群的生态特征具有明显的季节性变化规律，芦苇种群的盖度随着季节的变化逐渐增高，最高值出现在9月；芦苇种群的高度则随着季节变化逐渐升高；芦苇种群的密度随着季节的变化先升高，然后下降，9月中旬以后又略有回升；芦苇种群的地上生物量随着季节的变化呈现波动状态，但单株芦苇地上生物量则随着季节变化逐渐增加，其峰值出现在9月，随后受自身生长规律的影响，地上部分生物量减少。部分淹水状态下，芦苇种群高度、密度以及地上部分生物量的相对增长速率均与淹水深度变化速率显著正相关（n=5，P〈0．05）；而盖度主要受芦苇自身生长规律的影响，与地表淹水深度变化速率关系不明显。
英文摘要	Based on situation of flooding the observation data of ecological characteristics of Phragmites australis in Momoge National Nature Reserve during growing season in 2007, the Phragmites australis community growth and the water flooding dynamics were analyzed to changes of ecological characteristics of plant community and the impacts of flooding changes wetlands under natural state. The seasonal changes community and the dynamic changes of study the seasonal in semi - arid areas of coverage, height, density, above ground biomass of Phragmites australis community and the influence of the changes of flooding depth were analyzed in detail. The results showed that： growth process of Phragmites australis community had obvious seasonal regularity. The coverage of Phragmites australis community gradually increased with the seasonal change, reaching the highest level in the end of August and early September.The height of Phragmites australis community continued to rise until the end of growing season. The density of Phragmites australis community firstly increased and then decreased. The ground biomass of Phragmites australis community gradually increased with the season and its peak appeared in the end of August and early September, and then reduced because of impacts of its growth regularity. The depth of flooding had an important influence on the growth process of Phragmites australis community. The relative growth rate of height, density and above ground biomass showed significant positive correlation with the changing rate of depth of flooding（ n=5, p 〈 0.05 ） ; while coverage was mainly affected by its growth rhythm, the correlation between coverage and the depth of flooding was not obvious.
