| 摘 要： | 通过对日本落叶松与天然萌生阔叶树人工混交林的调查分析,结果表明:日本落叶松与天然萌芽阔叶树人工混交培育降低了培育成本,提高了生态效益,混交林培育28a后,林分生长稳定,生产力较高;混交林中的植物种类丰富,数量较多,各层次的物种多样性指数均好于人工营造的日本落叶松与白桦针阔混交林和日本落叶松纯林;日本落叶松与天然萌生阔叶树人工混交林,对恢复森林生态原始林貌有一定促进作用。

Effects of Mixture Silviculture of Larix kaempferi and Natural-Regenerated Broad-Leaved Trees |
| |
| Abstract: | Mixture plantation of Larix kaempferi and natural-regenerated broad-leaved trees were investigated.Re-sult shows that silviculture of Larix kaempferi and natural-regenerated broad-leaved trees reduce costs and improve the eco-efficiency,growth of the stand is stable after silviculturing mixed forest for 28 years and the productivity is more higher;plant species of mixed forest is abundant ,the number are larger;all levels of species diversity index are optimal than that of Larix kaempferi ,coniferous and broad-leaved mixed forest and pure forest of Larix kaempferi .Larix kaempferi and natural-regenerated broad-leaved trees have a certain promotion role in restoring original appearance of forest ecology. |
