| 摘 要： | 在调查北京八达岭林区不同混交模式林分生产力、生物量及其分配状况、林分土壤养分分配状况、混交距离对油松生长的影响与不同林分土壤水源涵养能力的基础上,研究不同混交模式的结构与功能关系。结果表明,油松-元宝枫块状混交林的生产力、生物量及其分配状况均好于油松-元宝枫带状混交林与油松纯林。油松-元宝枫块状混交林林下枯落物分解速度较快,积累量明显少于油松-元宝枫带状混交林与油松纯林,说明油松-元宝枫块状混交林具有较好的改良土壤作用,油松-元宝枫块状混交林的土壤物理、化学性质及其涵养水源功能好于油松-元宝枫混交林与油松纯林。此外,15a油松-元宝枫混交林混交距离应大于760cm;混交方式采用块状混交能起到较好的效果。 |

| Abstract: | The relationship between structure and function for different types of Pinus tabulaeformis and Acer truncatum mixed forests in Badaling Forest Centre was studied in terms of productivity,biomass,soil nutrients,effects of different mixed distances on the growth of P.tabulaeformis trees as well as water conservation capacity of different stands.Results show that the productivity,biomass and its distribution status of mixed forest with block-shaped structure are better than those of mixed forest with strip-shaped structure.The decomposing speed of litters under block-shaped mixed forest is quicker and the accumulated quantity is obviously lower compared with strip-shaped mixed forest and pure forest,indicating a better function on improving soil.Soil physical and chemical properties as well as water conservation capacity of block-shaped mixed forest are also higher than those of strip-shaped mixed forest and pure forest.Moreover,the mixed distance between P.tabulaeformis and A.truncatum should be longer than 760 cm in 15-year-old forest,and the better mixed mode is block-shaped. |
