摘要
提出了人工林稳定性的内涵及其评价标准.分析了影响沙地樟子松人工林稳定性的各种干扰因子,通过对沙地樟子松人工林造林成活、生长情况、对不良外界环境的抗御能力、林分寿命、林分结构和生产力的综合评价分析,认为沙地樟子松引种人工林基本上是稳定的;而生长在立地较好的丘间低地的林分,其稳定性大于沙丘顶部的林分;从抗枯梢病角度看,幼林的抗性大于中林;从林分密度和生产力角度来看.红花尔基沙地樟子松林稳定性高于章古台.
This paper defines the meaning of artificial forest stability and its evaluating standards. The various disturbing factors affeCting the stability of Mongolian pine plantation on sandy land were analyzed. Detailed studies were carried out on evaluating the survival degree of planting, the growth, the ability of resisting the adverse circumstances, life length, and the structure and the productivity of forest stand. Results show that the artificial forest stands of Mongolian pine introduced to sandy land are basically stable. The stands bowing on low sand dunes are more stable than those growing on high sand dunes. The young forests have higher disc ̄resistance than do the middle-aged forests. According to the density and the productivity of it, the stand growing on Honghuaerji sand land is more stable than in Zhanggutai.
