Abstract:Relative to pure stands, mixed forest of masson pine does better in the storage of timber, the improvement of forest microclimate conditions and the organic matter content of soil. The sequence of superiority of management models is masson pine-Chinese fir mixed forest, followed by masson pine-eucommia (Eucommia ulmoides Oliv.) mixed forest and masson pine-sweetgum mixed forest. This sequence is derived from the quantification and synthetic judgment of economic benefit, ecological effect and the nutrient content of soil among the three forest types. A suggested technique for the selection of an optimal management model is provided.
