| 摘 要： | 于2011年3、6和9月通过对太湖不同营养化湖区的5个标准采样位点进行采样分析，探讨了界面沉积物间隙水和上覆水中磷含量、pH及碱性磷酸酶活性的时空分布特征及相关性。结果表明，上覆水及沉积物间隙水中的总磷（TP）、可溶性正磷酸盐（SAP）、pH及碱性磷酸酶（ALP）活性均表现出明显的空间异质性和季节变化趋势。间隙水总磷（PW-TP）、间隙水可溶性正磷酸盐（PW-SAP）高于上覆水，分别最高高出0．082、0．042mg·L-1；上覆水pH值高于间隙水pH值，最高高出O．35个单位；间隙水中碱性磷酸酶（PW-ALP）活性高于上覆水中碱性磷酸酶（W-ALP）活性，最高高出13．244μg·mL·h-1。TP、SAP、pH及ALP活性在3、6、9月份中均以16#样品最高，其中6月份16#样品PW-TP、PW-SAP、上覆水pH及PW-ALP活性分别O．527、0．132、7．46和61．090μg·mL·h-1。参数相关性分析结果表明，W-TP与W-SAP、W-pH显著相关。W-SAP与PW-TP、PW-SAP、W-ALP、PW-ALP均显著相关。PW-TP与PW-pH显著相关性，与PW-ALP活性存在一定的相关性，但不显著。PW-SAP与PW-ALP显著相关。

| Abstract: | The spatial and temporal distribution of phosphate, pH and alkaline phosphatase activity in the interracial sediment interstitial water and the overlying water from five standard sampling sites of Lake Taihu were studied, and the relationships between them were determined, mainly based on the sampling time of March, June and September 2011. The results showed that the spatial differences among lake areas were significant and highly varied seasonally with the TP, SAP, pH and alkaline phosphatase activity in overlying water and the sediment interstitial water. Content of PW-TP and PW-SAP were higher than W-TP and W-SAP, with 0.082 and 0.042 mg.L1 at most respectively; value of W-pH were higher than PW-pH with 0.35 units at most; PW-ALP activity were higher than W-ALP with 13.244μg.mL-h1 at most. In March, June and September, the content of TP, SAP, pH and ALP activity were the highest at 16# site, and the content of TP, SAP, pH and ALP activity of 16# site in June were 0.527, 0.132 mg.L1, 7.46 and 61.09μg.mL.hl, respectively. Correlation analysis showed that W-TP was significantly correlated with W-SAP and W-pH; W-SAP was significantly correlated with PW-TP, PW-SAP, W-ALP and PW-ALE PW-TP was significantly correlated with PW-pH; but there was not evident relativity between the PW-TP and the PW-ALP. PW-SAP was significantly correlated with PW-ALP. |
