毛乌素沙地固沙造林针叶树种选择的研究

RESEARCH OF CONIFEROUS PLANT SPECIES SELECTION FOR SAND BINDING AFFORESTATION ON MU US SANDY LAND

选择樟子松、油松等五种针叶树种在毛乌素沙地进行栽植试验，通过对成活率与保存率、生长量、蓄积量、抗逆性等１４年的观测，从单项及多指标综合选优及排序，确立樟子松为毛乌素沙地针叶树造林的优选树种。

Five species of coniferous plant including Pinus sylvestvis var. mongolica Litvin., Pinus tabulaeformis Carr., Juniperus rigida Sieb. et Zucc, Larix principis rupprechtii Mayr. and Platycladus orientalis (L.) Franco were planted on Mu Us Sandy Land in the experiment. Based on the observing data of survial rate, growing increasment, amount of growing stock and resistant ability etc., Pinus sylvestris was decided to be the optimal plant for sand binding afforestation in this area, with the methods of comprehensive selection and ordinating.
