Effects of enclosing forest in valley forest of Altai Mountain
摘要
Abstract
The vegetation of closed area and non-closed area in valley forest of Altai Mountain were investigated.Forest structure, species diversity and important value of understory herbaceous plant were studied to find out the effect of enclosing.The results showed that: ( 1 ) Five years short-term enclosing forest had no significant influence on the overall performance of natural forest.(2)Ten more understory herbaceous species were found in closed area, and the relative increased content was about 77.5 %.At the same time, the vegetation coverage of understory herbaceous plant in closed area is 36.4% more than in non-closed area, relative increased 124.8 %.The Patrick index and Shannon-Wiener index of understory herbaceous plant in closed area were higher than those of non-closed area.The Simpson index and Pielou index had no significant difference between closed area and non-closed area.The conclusion could be drown that the understory vegetation of valley forest in Altai Mountain had apparently restored by enclosing forest and we should strengthen the management of closed area and extend enclosure years.关键词
