试论杉木林可持续经营的对策

Views on the Countermeasures for the Sustainable Management of Cunninghamia lanceolata Forests

改革传统林业经营措施 ,降低对林地干扰强度 ,增加杉木林不同生长发育阶段群落结构复杂性和物种多样性 ,杉阔轮栽 ,林地施肥 ,进一步加强宏观调控 ,加大杉木良种选育和推广力度等 ,均是实现杉木林可持续经营的较有效措施。为了全面实现杉木林可持续经营 ,则应针对不同产区、立地 (母岩 )

The authors raised the following relatively effective measures of realizing the sustainable management of Cunninghamia lanceolata forests:reforming the traditional forest management measures to reduce the disturbance intensity for forest land;increasing the community structure complexity and species diversity in different growth and developmental periods of C.lanceolata forests;planting C.lanceolata and broadleaved species in rotation;applying fertilizers to forest land;and further strengthening the macro-adjustment and control to speed up the improved-variety selection,breeding and popularization of C.lanceolata.In order to wholly realize the sustainable management of C.lanceolata forests,the relevant experiments on their sustainable management should be carried out and the appraisal target system study and approach to their sustainable management should be made in accordance with different provenances and sites(native rocks).
