摘要:
【目的】构建油松人工用材林可持续经营评价指标体系,以河北平泉黄土梁子国有林场油松用材林为实例,对其经营可持续性进行评价与分析。【方法】通过查阅文献资料并结合前人研究结果,以全面、科学性为指导原则,选择环境、经营、社会、经济4个方面共83项指标层指标,设计问卷征求相关领域专家意见,运用灰色统计法从中筛选出重要程度为“高”的指标,从上述4个方面构建可持续经营评价指标体系,并利用1~9标度法和层次分析法确定各指标权重值。以河北省平泉市黄土梁子国有林场为例,通过咨询、实地调查、发放问卷方式获得各指标现状值,再通过查阅国际和国内标准、参考相关研究结果及指标自身情况确定各指标标准值,对林场油松人工用材林经营现状进行评价分析。【结果】从83项指标中筛选出28项重要程度为“高”的指标,构建了包含4个约束层指标、12个一级指标层指标和28个指标层指标的油松人工用材林可持续经营评价体系。其中,社会指标最为重要,权重值为0.351 165;环境指标的权重最低,为0.164 793;经济指标权重为0.295 084,经营指标权重为0.188 957。用该指标体系对黄土梁子国有林场油松人工用材林进行可持续经营评价,最终得分为79.68分,处于中上等水平,表明林场现阶段油松人工用材林的生长状况、经营模式、可持续性较好。【结论】研建的油松人工用材林可持续经营评价指标体系具有科学性、适用性,可反映林分可持续经营现状。

Construction and application of sustainable management evaluation index system for Pinus tabulaeformis timber forest
ZHENG Xiaomin,ZHANG Xuan,DUAN Jie,et al
Abstract:
【Objective】A sustainable management evaluation index system of Pinus tabulaeformis plantation was established and used for evaluation of P. tabulaeformis plantation in Huangtuliangzi National Forest Farm,Pingquan,Hebei.【Method】By reviewing literature and combining previous researches,a total of 83 indicators were selected from four aspects,including environment,management,society and economy.Questionnaires were designed to obtain opinions of experts in relevant fields,and the indicators with high importance were selected by grey statistical method.The sustainable operation evaluation index system was constructed from above four aspects,and weight value of each index was determined by 1-9 scale method and analytic hierarchy process.Taking Huangtuliangzi National Forest Farm in Pingquan,Hebei as example,this paper obtained the current value of each index by means of consultation,field investigation and questionnaire distribution,and determined the standard value of each index referring to international and domestic standards,relevant research results and the index itself. Then,the management status of artificial timber forest of P. tabuleformis in the forest farm was evaluated.【Result】A total of 28 indicators with high importance were selected from 83 indicators.A complete evaluation index system framework for sustainable management of artificial timber forest of P. tabulaeformis,including 4 constraint layer indexes,12 first-level index layer indexes,and 28 index-layer indexes,was then constructed.Social indexes were the most important,with a weight of 0.351 165,while environmental indexes had the lowest weight of 0.164 793.The weights of economic indexes and business indexes were 0.295 084 and 0.188 957,respectively.The final score of artificial timber stand of P. tabulaeformis in Huangtuliangzi National Forest Farm evaluated by the established system was 79.68,which was in medium and high levels.The P. tabulaeformis had good growth status,management mode,and sustainability.【Conclusion】The established evaluation index system for sustainable management of artificial timber forest of P. tabulaeformis was scientific and applicable,and it could reflect current situation of sustainable management of stands.
