改善千岛湖森林结构与功能的研究

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了相应的对策，认为调整产业结构、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，充分运用人为有利干扰则是其重要保证。

Study on Forest Structure and Function Adjustment of Qiandao Lake

Secondary Pinus massoniana forest is the main forest type of Qiandao Lake. It has unique landform but also has problems such as: low bio_diversity index, un_stability, weak eco_function, fetal danger of caterpillar and nematode. The single landform of Qiandao Lake is not inline with the development of tourism. It is extremely urgent that improving forest structure. This paper proposed that adjusting industry structure, strength classified forest managing and mountain closure are preconditions, strength scientific study and full using of human disturbance are most important guarantee of strategies of improving forest structure and function of Qiandao Lake efficiently.
