| 摘 要： | 为了研究湿地香蒲种群对不同水深环境的生态响应规律和特征,分别于2018-06-30,2018-07-30,2018-08-29,2018-09-28进行野外采样,通过调查和室内化学分析,探讨了7个不同淹水深度下香蒲种群生长指标、水质因子和底泥因子的变化情况。结果表明:在不同淹水深度下,香蒲的生长指标差异显著,当淹水深度为50 cm时,香蒲的生长状态最优;4个采样日石佛寺水库水样大体呈弱碱性,底泥类型为中性偏酸性;随着淹水深度的增加,水样中的溶解氧(DO)、硝态氮(NO3-)和亚硝态氮(NO2-)质量浓度逐渐减小,总氮(TN)和氨氮(NH4+)质量浓度增大,底泥中氨氮(NH4+)和有机碳(SOC)质量分数总体增大,总氮(TN)、硝态氮(NO3-)和亚硝态氮(NO2-)质量分数逐渐减小,电导率总体逐渐降低,总磷(TP)和速效磷(AP)的质量分数基本呈波动状态。底泥和水体中氮元素的含有量对香蒲的生长影响较大。

| Abstract: | In order to study the ecological response law and characteristics of Typha angustifolia in different water depth environments on 2018-06-30, 2018-07-30, 2018-08-29, and 2018-09-28, the changes of growth indexes, water quality factors,and sediment factors of Typha angustifolia under different flooding depths were discussed through field sampling survey and indoor chemical analysis. The results showed that the growth indexes of Typha orientalis Presl were different at different flooding depths. At the water depth of 50 cm, the growth state of Typha orientalis Presl was the best. The water samples of Shifosi reservoir were weakly alkaline over 4 sampling days, and sediment types were acidic neutral sediment. With the increase of the water depth, the mass concentration of dissolved oxygen (DO), nitrate nitrogen (NO3-),and nitrite nitrogen (NO2-) in the water samples gradually decreased, and the mass concentration of total nitrogen (TN) and ammonia nitrogen (NH4+) increased. With the increase of water depth, the overall quality score of ammonia nitrogen (NH4+) and organic carbon (SOC) increased, the quality score of total nitrogen (TN), nitrate nitrogen (NO3-) and nitrite nitrogen (NO2-) decreased gradually, the overall conductivity decreased gradually, and the quality score of the total phosphorus (TP) and available phosphorus (AP) fluctuated substantially. The content of nitrogen in sediment and water had a great influence on the growth of Typha orientalis Presl. |
