湖南优质工业材用毛竹评价指标体系的建立

Establishment of Evaluation Index System of High-Quality Phyllostachys heterocycla for Industrial Timber in Hunan Province

为给优质工业材用毛竹的选育及营建提供理论依据,采用样地调查法进行湖南毛竹林分结构调查,采用标准竹解析法测定毛竹林分立竹秆型结构和生物量,参照GB/T 15780-1995标准采集竹材材性测试样品并采取实验室测试分析法测定竹材的物理、力学与化学性质指标。在系统研究调查数据的基础上,结合专家意见,确定了胸径、胸高竹壁厚、材质、全高、秆质量、秆型和尖削度等7个一级指标及对应的21个二级指标,建立了优质工业材用毛竹评价指标体系,并运用层次分析法(AHP)确定了各指标的权重。经一致性检验可知,其结果具有满意一致性。

In order to provide a theoretical basis for selection, breeding and planting of highquality Phyllostachys heterocycla for industrial timber, the structure of 19. heterocycla forest was investigated by using sample plot investigation method, culms form structure and biomass of bamboo were determined by using sample bamboo analytical method, samples for testing wood properties were collected referring to GB/T15780-1995, and physical, mechanical and chemical properties indexes were determined by using laboratory test and analysis method. Seven first grade indexes and 21 corresponding second grade indexes were determined, based On results of systematically researching the data and advices from experts, and the seven first grade indexes were diameter at breast height, bamboo wall thickness at breast height, material quality, height, culms mass, culms form, tapering grade, respectively. An evaluation index system of high-quality P.. heterocycla for industrial timber was established, and the weights of all indexes were determined by using analytic hierarchy process. The results of single test showed satisfying consistency.
