摘要
通过对白桦天然林立地类型、生产力状况和生长进程等因子的实际调查,归纳出白桦天然林现状.结合特定的经济环境条件,利用白桦实生苗在参后还林地营造3种林分类型白桦速生丰产人工林7 hm2,提出了8项配套的丰产集约栽培技术措施,结果显示:白桦造林成活率达98%,林木生长量提高1.58～5.71倍;采用灰色系统理论GM(1,1)模型与数学模型相结合的方法,建立白桦人工林和天然林树高、蓄积生长模型,制订出3种不同类型白桦人工林7～20 a胸径、树高、株数量、材积的生长量丰产指标,给出了白桦工业用材林培育的方法和途径,研究成果可为白桦速生丰产林的建设提供科学依据.
The present situation and characters of natural Batula platyphylla plantation were summarized through actual investigation on side type, productivity condition and growth process of natural Batula platyphylla. The eight measurements with highyield and intensive technologies were presented combining special economy environment, analyzed that the fast growing and high yield plantations 7 hm2 of Batula platyphylla with three kinds of stands was builded after Batula platyphylla seedlings were planted in returned forestland from Ginseng land, the survival rate of Batula platyphylla plantation can reach 98%, the growth increment increases 1.58 - 5.71 times; The height and growth model of natural Batula platyphylla and Batula platyphylla plantation were established by using GM （ 1,1 ） and mathematics model, the diameter, tree height, tree numbers and highyield index of three different types of Batula platyphyUa plantation 7 - 20 a were formulated, the cultivation methods and ways of Batula platyphylla used for industry were given, which can provide scientific basis for the fast growing and high yield plantations.
