Abstract
Based on 7-year-long Bretschneidera sinensis and Cunninghamia lanceolata mixed forest,and Bretschneidera sinensis pure forest afforestation compare experiment ,results showed that:the growth of 8-year-old Bretschneidera sinensis and Cunninghamia lan-ceolata mixed forest was significantly higher than that of B.sinensis pure forest,the average B.sinensis plantation diameter was 3.7 cm,the average tree height was 3.02 m,the average saving rate was 91.4%,were 15.6%,9.0%,6.7%higher than pure forest;the average of B.sinensis downhill afforestation diameter was 4.4 cm,the average tree height was up to 3.65 m,the average saving rate was 91.7%,respectively,were 29.4%,32.2%,7.3% than the downhill,and 69.2%,65.1%,14.3% higher than the uphill.The mixed forest canopy density was 0.7,0.25 higher than that of B.sinensis pure forest canopy density significantly.关键词
