| 摘 要： | 关于飞播成效与立地因子之间的关系,国内早期飞播造林已有较多的定性研究和报道,但在定性与定量相结合方面做得较少。本文根据鄂西北郧西县庙川播区油松飞播调查资料,采用方差分析和数量化逐步回归分析法,就其成效与立地条件之间的关系进行了研究,为今后选择播区、评价播区立地质量和预测飞播成效提出可行性评估的依据。

| Abstract: | The air seeding effects in Pinus tabulaeformis Carr. have been studied bythe way of variance analysis and quantitative gradual regression. The resultsshow that among many factors elevation, slope site, thickness of soil layerand slope gradient have combined influence on air-seeding effects. The mu-ltiple linear equation has been formulated by the relations between these fourcritical factors and aerial seeding effects, and the more satisfactory resultshave been obtained in the use of predicting air seeding effects. Therefore,this study will be very useful for choosing site conditions and evaluating sitequality of seeding area, and increasing aerial seeding effect, and also hascertain significance for predicting effect of aerial seeding at early stage. |
