| Abstract: | The stock growth was measured regularly in the permanent sample plots established in the public welfare forest.From 2007 to 2010,the net stock growth were 0.642 8 m3,0.641 9 m3,0.952 6 m3,1.179 4 m3,0.237 4 m3 and 3.627 1 m3 in plot 1,plot 2,plot 3,plot 4 and plot 5,and the growth rate were 12.8%,4.73%,8.12%,3.87% and 1.52%,respectively.The effective management could increase the stock steadily and enhance the ecological function and economic benefits of forest year by year. |
