杉木是我区主要造林树种,1978年以来,我省杉木栽培科技协作组先后进行了产区区划、立地类型划分和地位指数表的编制等工作。在此基础上,为了检验立地类型划分的可靠性,探索造林规划设计工作中适地适树发展杉木林的定量依据,即予估宜林地在一定立地条件下营造杉水林的地位指数,使造林和经营在立地质量评定上标准一致,给连续经营、集约经营提供较为可靠的依据。所以,用数量化理论来研究杉木林立地质量是非常必要的。
Cunninghamia lanceolata is the main afforestation species in our district. Since 1978, the Cunninghamia lanceolata Cultivation Collaborative Team in our province has successively carried out the work of zoning of production areas, division of site types and preparation of the status index table. On this basis, in order to verify the reliability of the site type classification, and to explore the afforestation planning and design suitable for the development of Chinese fir plantation quantitative basis, that is, to assess the forest site in a certain location to create Cedar Forest status index Afforestation and management standards in the site of the same quality assessment, continuous operation, intensive management to provide a more reliable basis. Therefore, using quantitative theory to study the quality of Chinese fir stands is very necessary.
