摘　要：馬尾松天然次生林是千島湖的主要森林植被類型，雖具獨特風韻，但生物多樣性低、穩(wěn)定性差、生態(tài)功能脆弱，面臨松毛蟲和松材線蟲的致命威脅。千島湖森林景觀的單一性也跟不上旅游業(yè)發(fā)展的需求，快速改善其森林結構與功能迫在眉睫。根據(jù)調研結果，就如何快速有效地改變千島湖森林結構與功能提出相應對策，調整產(chǎn)業(yè)結構、加強森林分類經(jīng)營和加大封山育林力度是三個先決條件，而加強科學研究和充分運用人為有利干擾則是其重要保證。

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.
