摘要
总结了马尾松×木荷异龄混交的试验结果和造林技术,分析和揭示了珠江流域南热带季风气候区马尾松低效防护林采取异龄混交木荷改造后的林分结构、生物量、凋落物、土壤理化性质、林地涵养水源和固土功能以及林分生长量等的变化规律及其影响。全面评价了马尾松×木荷异龄混交林的综合效益,为低效马尾松防护林改造提供了示范样板和技术支撑。
In this paper,test results and afforestation technique of Pinus massoniana Lamb.×Schima superba mixed forest were summed up.After Pinus massoniana Lamb.inefficient protective forest was mixed by uneven-aged Schima superba in ZhuJiang basin,variation and affect of forest structure,biomass,litter,physicochemical property of soil,conserve water and sand-fixation of forest land and stand growth of it were analyzed and revealed in south tropical mason climate.Also comprehensive benefits of Pinus massoniana Lamb.×Schima superba mixed forest were evaluated roundly.All of above provided demonstration model and technical support to transform inefficient Pinus massoniana Lamb.protective forest.
