公益林与商品林分类指标体系及技术标准的研究

STUDIES ON TECHNICAL CRITERIA AND INDEX SYSTEM FOR CLASSIFYINGPUBLIC BENEFICAL FOREST AND COMMERCIAL FOREST

林业分类经营是林业部提出的一项深化林业改革的重要措施，如何科学合理地划定公益林与商品林，是当前实施林业分类经营战略迫切需要解决的问题。本文从系统、可行、科学的角度对森林功能性分类系统，划分公益林与商品林的分类指标体系及技术标准进行了探讨。研究提出将森林按主导功能分别３个层次，分为公益林和商品林２大类５个亚类２１个森林类型；公益林选用生态脆弱性等级与生态重要性等级２个复合指标，商品林选用投资利润率、净现值、森林蓄积生长量和地利等级４个指标构成分类指标体系；并分别森林类型确定了技术标准。

Forestry classification management is an important measure for forestry reforming which is put forward by Ministry of Forestry. How to classify Commercial Forest(CF) and Public benefical forest (PB) scientificly and rationally is the problem to be solved urgently for forestry classification management. The paper approaches the subjects of the forest functional classification system, PB and CF classifying index system and technical standard from the systematic, feasibly and scientific angles. According to forest dominant functions, forests are classified into two groups of PB and CF, five subgroups and 21 forest types from three levels. Two complex indexes of ecological fragility class and ecological importance class are used by PBF. The classification index system of CF is consisted of four indexes, invest profit, net value, forest volume increment and site convenience class. The technical criteria are determined according to the forest types.
