The woodland area reached to 648.3 hm2 from 1998 to 2008, forest coverage rate increased 0.03%. Volume of energy woodland increased to 2261408 m^3 and forest volume reached to 2443026 m^3 , plantation area increased 5.73% , growth rate of plantation volume was up to 24.50%. Increased reasons of forest area and volume in study period were discussed in this pa-per. |
