汪建敏 王光貴 徐高福 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(fēng)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(jié)構(gòu)與功能迫在眉睫。根據(jù)調(diào)研結(jié)果，就如何快速有效地改變千島湖森林結(jié)構(gòu)與功能提出相應(yīng)對策，調(diào)整產(chǎn)業(yè)結(jié)構(gòu)、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(xué)研究和充分運用人為有利干擾則是其重要保證。 Study on Those Problems and the Countermeasure Improve the Forest Structure and Function in Thousand-isle-lake WANG Jian-min（Xin an River
Development Controlling Corporation of Chun an in Zhejing
Province，Chun an，Zhejing 311700 China） 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. |
