【摘要】 本研究根据1978年以来,在河南省洛宁县调查的108个标准地材料整理而成。文中分析比较了淡竹三种经营类型林分结构与产量的关系。结果表明,影响淡竹林产量的主要因素是竹林的年龄结构、林分密度和叶面积指数。在竹林经营管理上,由于不合理的采伐利用,导致竹林结构的破坏,竹株更新能力逐渐衰退,因而当前淡竹林的产量表现出下降的趋势。根据调查分析数据,文中提出了改善林分结构的措施以及合理经营的指标。更多还原

【Abstract】 This paper is based on the study of 108 sample plots in Luoning,HenanProvince since 1978,comparing and analysing the relationship between the standstructure and the production in three types of management stands.The resultsobtained show that the bamboo age structure,stand density and leaf area indexare the main factors that affect the yield.Due to unreasonable cutting,the bambeostructure is destroyed,its regenerative power falls into a decline gradu-ally.According to the analytical datum,the measure to improve the stand structureand the rational management targets are brought forward.更多还原
