摘要

<正>松树是我国重要的造林先锋树种与景观绿化树种,然而,近年来在许多地方发现有不明原因、不同症状的枯萎松树,不同种类的寄生线虫在枯萎松树中被发现。笔者对松树体内的寄生线虫以及这些寄生线虫的致病性进行了综述。到目前为止,在我国松树上已经发现寄生线虫有11属42种以及11个未定种。除松材线虫外,一些线虫如拟松材线虫、Bursaphelenchussexdentati等也能够引起某些松树的死亡。

Abstract

The changes of water quality at an upstream river of Taihu Lake near Linzhuang Port which located in Dapu town, Yixing city were investigated from October 2004 to September 2005. The results showed that the concentration of TN was worse than class V water quality all over the year. The other indices were near class II to class IV. The eutrophication of water was mainly represented as the exceeding of TN. Except the concentration of TN and TP, the other water quality indices were worse in growth season than that in non-growth season. The changes of BOD5, CODMn, Chla were mostly affected by temperature. Temperature was the active factor for BOD5 and COD. Precipitation only had positive correlation with the concentration of TP. It showed that TP was influenced little by ecological process of river ecosystem than others such as TN.
