摘  要：
在大兴安岭林区,通过带状改造和块状改造方式分别对阔叶低质林、柞树低质林和白桦低质林进行改造,分析不同改造方式对3种不同类型低质林生物多样性的影响。结果表明:阔叶低质林经带状和块状改造后,各试验区中生物多样性较高的是S3>G4>S2>G3>G5;柞树低质林经改造后,各试验区中生物多样性较高的是S3>S2>G5>G4>S4;白桦低质林经带状和块状改造后,各试验区中生物多样性较高的是G4>S3>G3>G5>G6;综合3个试验区生物多样性恢复效果,带状改造试验区生物多样性高于块状改造试验区;带状试验区以10、14 m带宽进行改造,块状试验区以225～625 m2进行改造,试验区生物多样性较高。

摘  要：
An experiment was conducted to study the effects of different transformation measures(strip transformation and patch transformation) on biodiversity of three types of low-quality forest stands in Great Xing'an Mountains,namely mixed forest,Xylosma racemosum forest,and Betula platyphylla forest.Results show that the biodiversity of the mixed low-quality forest in the experimental site S3 was highest after strip transformation and patch transformation,followed by G4,S2,G3 and G5;the biodiversity of X.racemosum forest in the experimental site S3 was highest,followed by S2,G5,G4 and S4;the biodiversity of B.platyphylla forest in the experimental site G4 was highest,followed by S3,G3,G5 and G6.The biodiversity in the experimental sites transformed by strips was higher than that by patches according to the comprehensive restoration effects of biodiversity in the three types of forests.The highest biodiversity was observed in the experimental sites transformed by strips with a width of 10 m or 14 m,as well as the experimental sites transformed by patches with an area ranging from 225-625 m2.
