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。
This study is based on 108 standard materials surveyed in Luoning County, Henan Province since 1978. The paper analyzes and compares the relationship between stand structure and yield of three types of commercial bamboo. The results showed that the main factors affecting the yield of fresh bamboo are the age structure of bamboo forest, stand density and leaf area index. In the bamboo forest management and management, due to unreasonable harvesting and utilization, leading to the destruction of the bamboo forest structure, bamboo regeneration capacity gradually declined, so the current production of light bamboo showed a downward trend. According to the survey and analysis data, the article put forward measures to improve the stand structure and reasonable management index.
