| Abstract: | By investigating the demonstration-forest plot:through integrated control. the results show that the volume increase rates of young tarests and mature. forests are much higher than those that haven't been operated integrated control. young forests can make woods increase 73. 21 percent averagely and volume' increase 27. 68 m3 per hectare. while mature forests can make woods increase 76. 04 or 80. 16 percent and volume increase 178. 95 m3 or 213. 30 m3 per hectare. This research achievement 11as been spread in Heilongjiang Province. its spreading area reaches to 21 thousand hectare. calculated by volume increase. the direct economic benefit is 53 million Yuan. |
