摘要:通过查阅相关研究资料,根据林下更新层生境特点,结合专家意见,采用层次分析法建立了7个生境因子的评价指标体系,并建立了判断矩阵,经过一致性检验,确定了7个生境因子的权重。应用AHP-模糊综合评价法,建立3级评分标准和生境质量分级标准的林下闽楠更新层生境质量评价模型,并利用该评价模型对林下闽楠更新层生境进行客观全面评价与分析,验证模型的应用。结果表明:应用该评价模型评价林下闽楠更新层生境质量,评价精度高,操作简便,为林下更新层开发利用提供了参考依据。

Abstract:According to habitat characteristics of Phoebe bournei regeneration layer and suggestions from experts, a habitat quality evaluation model was established for 7 habitat factors based on analytic hierarchy process. With the judgment matrix and uniform examination, the 7 habitat factors weight were determined in this model. The evaluation models of scoring criteria with 3 rating and grading standard of understory P.bournei regeneration layer habitat quality evaluation model were established using AHP-fuzzy method.A overall evaluation on the habitat quality of understory P.bournei regeneration layer was made and the results showed that the model can provided some precision basis of theory for the application of development and utilization of forest regeneration layer.

随着人们对复层林经营的认识提升,林下更新层培育被广泛应用于低质低效生态公益林和人工针叶纯林的改建。更新层生境质量作为衡量林下造林更新适宜程度和利用价值的指标,其质量好坏直接关系到更新层培育的成效。更新层生境质量评价是对更新层立地质量和潜在生产力的评判及预测,是复层林经营的基础,可为林下更新以及经营管理决策提供技术支持。如何科学、系统、客观地评价林下更新层生境质量成为关键所在。当前在生境质量方面的研究有报道[1-2],但有关林下更新层生境质量评价方面的研究较少。……
