杉木山杜英混交林林分生产力及生态效益的研究

本文通过对山杜英纯林、杉木山杜英混交林的生产力、土壤肥力和林分燃烧性的研究，结果表明：与杉木纯林相比，混交林不仅能够提高林分生产力，同时还具有培肥土壤，提高林分水源涵养能力，降低林分燃烧性等良好生态效益，营造杉木山杜英混交林是科学经营杉木连栽地的有效措施之一

A Study on productivity and Ecological Benefit in Mixed Stand of Chinese Fir and Sylvestrial elaeocarpus

Through a study on productivity, soil fertility and combustibility under mixed stand of Chinese fir, Elaeocarpus sylvestris and pure stand of Chinese fir, the result indicated that, compared with Chinese fir pure stant, the mixed stand not only has a higher stand productivity, soil fertility, but also has a better water conservation capacity which can reduce stand combustibility. Thus, planting mixed stand of Chinese fir and Elaeocarpus sylvestris is one of effective ways to control productivity decline for continous planting of Chinese fir.
