摘要:
以太湖流域典型平原圩区为研究对象，分析了圩区磷流失的季节变化及主要影响因子，研究结果表明：圩区总磷质量浓度变化范围为0.039~0.306 mg/L，全年大部分时间低于Ⅲ类水标准；丰水期磷流失比平水期和枯水期严重；春季水体磷质量浓度降低，夏季开始升高，秋季达到最高，冬季缓慢下降。利用Person相关分析得出总磷、颗粒态磷及溶解态磷与温度显著正相关，颗粒态磷在总磷中占比与湿度及降水显著正相关，溶解态磷在总磷中占比与湿度及降水显著负相关。该研究助于水管理者识别磷流失机制，从而采取科学措施控制水体富营养化。
Abstract:
Taking the typical plain polder area of Taihu Basin as the research object, the seasonal variation and main influencing factors of phosphorus loss in polder area were analyzed. The results showed the total phosphorus (TP) concentration of polder varied from 0.039 to 0.306 mg/L, lower than the national Ⅲ class water standard in most time of a year. The phosphorus loss was more serious in wet season than in normal season and dry season. Moreover, the phosphorus concentration decreased in spring, began to increase in summer, reached the peak in autumn, and declined gradually in winter. The Person correlation analysis showed that total phosphorus, granular phosphorus and dissolved phosphorus were significantly positively correlated with temperature; the proportion of granular phosphorus in total phosphorus was significantly positively correlated with humidity and precipitation; the proportion of dissolved phosphorus in total phosphorus was significantly negatively correlated with humidity and precipitation. This study helps water managers identify the mechanism of phosphorus loss and take scientific measures to control eutrophication in water bodies.
