| 摘 要： | 枫香杉木混交林的生产力及生态特性研究表明，枫香与杉木混交种间关系协调，林分生长量和生产力较高，林分空间分布格局合理，可以调节林分小气候，改善土壤理化性状，提高土壤微生物数量和土壤酶活性，从而促进林木生长，是一种较好的混交组织。营造枫香杉木混交林是改造杉木低产林、防治地力衰退及扩大优良乡土阔叶树种植范围的有效途径之一，值得推广应用。表７参１２

Productivity and ecological characteristics of mixed forest of Chinese sweet gum and Chinese fir |

| Abstract: | A study on productivity and ecological characteristics of mixed forest of Chinese sweet gum and Chinese fir was carried out.The results show that the mixed forest has a harmonize species relation,with relative high productivity and rational special structure.The mixed forest has ameliorated soil physical and chemical properties,stimulated the activities of microbes and enzymes,and improved the growth of both Chinese sweet gum and Chinese fir.It is,therefore,an advantageous mixed forest in rebuild of poor yield plantation of Chinese fir and control of site degradation. |
