摘要: 在对丹江口库区龙口林场水源涵养林不同林分类型调查的基础上,综合考虑林分结构、立地条件和演替更新潜力等因素,运用层次分析法对影响林分质量的10个指标进行了权重评价和排序,结合调查数据计算出不同林分质量等级综合数值。结果表明:(1)林分结构对林分质量影响最重要,郁闭度、林分密度、土壤厚度和枯落物厚度等指标成为影响林分质量的关键因素,而幼苗数量对林分质量贡献较少。(2)丹江口库区龙口林场水源涵养林不同林分质量大部分处于中等和较差质量等级,进行林分改造提升林分质量和生态防护功能的空间较大。(3)采用层次分析法进行水源涵养林林分质量评价结果与实际相吻合,可以客观地反映研究区林分质量的发展状况。

Abstract: Based on a survey in different stand types of water conservation forest, and a comprehensive consideration of forest structure, site condition, succession update potential and others factors, we evaluated and sorted ten indexes affecting stand quality by using the analytic hierarchy process in Longkou Forest Farm of Danjiangkou reservoir area, Hubei province, China. Our results showed that:(1)Forest structure was the most important factor affecting the stand quality, whereas canopy density, stand density, soil thickness and litter depth were the key factors for stand quality.(2)The stand quality of the water conservation forest ranked on modest and poor quality level in Longkou Forest Farm of Danjiangkou reservoir area. Therefore, we believed that there was a large space for improving the regional stand quality and ecological protective functions though the stand modification.(3)The result of stand quality evaluation by analytic hierarchy process coincided with the actual situation, so this method could objectively reflect the quality of the stand development condition.
