【摘要】 从21个立地因子中回归筛选出10个,与立地指数建立了数量化理论Ⅰ模型,并编制了开化杉木数量化立地指数得分表。分析结果表明,海拔、母岩、土壤厚度和土壤质地是影响开化杉木生长的主导立地因子。文中对这4个项目各类目组合而成的48个立地类型进行了数量化评价,预估出了各立地组合所潜在的生产能力。更多还原

【Abstract】 Appling Quantitative theory I, 10 site factors were selected out and used to compile the site index scoring table, where R=0.7401, S=1.59. The results showed that altitude above sea level, parent rock, soil thickness and texture were mainly site factors affecting growth of C. lanceolata in Kaihua County. At last, the potential productibility for each site type was estimated.更多还原
