| Abstract: | Research results have shown that mixed China fir and Chinese cryptomeria forests can bring about a stable and coordinated stand structure and improve stand microclimate. A 1 6-year old mixed forest has a 27. 5 - 50. 4% higher stock per unit area than a pure Chian fir forest and a 15. 5 - 36. 3% higher than a pure Chinese cryptomreia forest. Additionally. mixed plantdtion of China fir and Chinese cryptomeria can be used for transforming a low-yield forest and expanding areas of planting China fir,thus having a higher economic and ecologic benefits than a pure forest. |
