【Abstract】 In the paper,ecological factors in several kinds of conifer-hardwood mixed plantation were surveyed compared with pure stands.The conifers are Pinus koraiensis and Larix kaempferia while the broad-leaved species are Alnus hirsute,Tilia amurensis,Betula platyphylla,Kalopanax septemlobus,and Fraximus mandshuria.The result show that ecological conditions in mixed plantations are better than that of pure stands.The mixed plantation have functions such as temperature regulation,decrease evaporation and wind velocity,increase nutrients in the soil,and lead to a higher yield.更多还原
