安远县杉木、马尾松产量转换立地评价

本文在研究安远县杉木、马尾松地位指数表、数量比地位指数表及立地分类的基础上,用蓄积量作为评价立地质量的指标.并根据数量化理论,以生态立地因子为依据,分析本县主要用材树种——杉木、马尾松在同一立地条件下地位指数的关系,结合蓄积量收获预估模型,预估杉木、马尾松的蓄积量,作为相同立地条件下杉木、马尾松生产潜力的估测值,进行多树种产量转换立地评价。为经营者根据立地条件选择生产潜力大、经济效益高的树种提供科学依据。

SITE EVALUATION BY THE TRANSFORMATION OF GROWING STOCK BETWEEM CHINESE FIR AND MASSON'S PINE IN ANYUAN

Based on site classification and projecting site index tables and quantized site index tables for China fir Masson's pine, growing stock per ha, was used to be a evalution index on site quality. Through the way of quantification, the relationship of site indexes of China fir and Masson's pine, which arc two major species for timber in Anyuan County, in the same site type, was discussed on the bosis of ecologic factors of site. Adopting yield predicting models, the growing stock of both species was predicted as the potential productivity of both species on the same site, and site quality could be evaluted by the transformation of growing stock between multi-species. So, the transformation provided a basis of selecting the tree species with high potential productivity and good economic effect on different site types.
