中文摘要:
      针对地力衰退与维护这一林业研究热点,文中从林分生产力、土壤理化性质、土壤养分、土壤微生物、土壤酶活性、自毒作用6个方面阐述了马尾松人工林的地力现状。众多研究表明,马尾松人工林尚未出现地力衰退,其产生地力衰退的原因主要是不合理的营林措施。同时从轮作、混交林、发展林下植被、林地施肥、生态系统管理等方面介绍了马尾松人工林地力维护进展,并对马尾松人工林地力维护研究趋势进行了展望。
英文摘要:
      Soil degradation and its improvement is always a hot issue of forestry research. The current situation on site productivity of Pinus massoniana plantation is reviewed in this paper from 6 aspects, i.e., stand productivity, soil physic-chemical properties, forest land nutrient, soil enzyme activity, soil microorganism, and auto-toxicity. A number of studies showed that P. massoniana plantation does not trigger soil degradation, while the unreasonable forest management is the primary cause to soil degradation. To improve soil fertility, countermeasures were put forward including tree rotation, mixed forest, understory vegetation maintenance, fertilization and ecosystem management. Finally, the trend and orientation of the research on soil improvement was prospected.
