Decomposition of mixed foliar litters from the four typical plantitions in upper reaches the of the Minjiang River was studied by using the litterbag method. 摘要采用尼龍分解袋的方法，對(duì)四川岷江上游地區(qū)連香樹(shù)、云南松、糙皮樺和云杉4種典型人工林凋落葉進(jìn)行田間混合分解試驗(yàn)。

With the litterbag method,the decompositions of two submerged macrophytes(Potamogeton pectinatus and Potamogeton crispus)growing in WuLiang SuHai Lake were in investigated in 58 days consecutively. 利用分解網(wǎng)袋法,對(duì)烏梁素海兩種優(yōu)勢(shì)沉水植物進(jìn)行了連續(xù)58天的室內(nèi)腐爛分解試驗(yàn),分析研究了不同水體營(yíng)養(yǎng)鹽濃度下這兩種植物的干重?fù)p失及其氮、磷的消減過(guò)程。
