摘　要：马尾松天然次生林是千岛湖的主要森林植被类型，虽具独特风韵，但生物多样性低、稳定性差、生态功能脆弱，面临松毛虫和松材线虫的致命威胁。千岛湖森林景观的单一性也跟不上旅游业发展的需求，快速改善其森林结构与功能迫在眉睫。根据调研结果，就如何快速有效地改变千岛湖森林结构与功能提出相应对策，调整产业结构、加强森林分类经营和加大封山育林力度是三个先决条件，而加强科学研究和充分运用人为有利干扰则是其重要保证。

Abstract：Pinus massoniana natural secondary forest is the main forest vegetation type in Thousand-isle-lake, despite its unique great charm, it has been confronted with fatal threats of Dendrolimus punctatus and Bursaphelenchus xylophlus due to its low biologic variety, poor stability and weak ecological function. Furthermore, the oneness of forest landscape in Thousand-isle-lake cannot keep up with the development of tourism. Hence, it is urgent and important to improve rapidly the forest structure and function in Thousand-isle-lake. On the basis of investigation, corresponding countermeasures to change rapidly and efficiently the forest structure and function in Thousand-isle-lake are introduced in this paper, with the viewpoint that adjusting industry structure, strengthening forest classifying management and putting more energy into protecting woods are three preconditions, meanwhile, reinforcing scientific research and making fully use of favorable contrived interference are its important guarantee.
