Abstract: Pure coniferous forests planted repeatedly on the same area have many defects. Planting mixed coniferous broad-leaved forests is one of the most available methods to dispel these defects. Significant effects have been seen from experiments done in the past seven years. It was found that the mixed forest of Cunninghamia lanceolata-Michelia macclurei with rational proportion of arrangement has shown significant economical and ecological benefits.The advantages of mixed forest are as follows:increasing biological productivity and utilization of solar energy,accelerating the decomposition process of organic matters and accumulation of nutrients and humus on the woodland,improving the mechanical composition,aeration condition and capacity of water retaining and supply of the soil, promoting the activities of microbes, and decreasing insect pests.
