摘　　要：栎类资源在河南省森林资源中所处的地位是重要的,具有多种经济价值和生态价值,森林质量直接影响到这些价值的实现。基于河南省森林资源二类调查数据,从栎类资源数量、单位蓄积量、资源重要性指数3个指标来评价栎类资源的森林质量,结果显示:(1)栎类资源比重高的区县,其单位蓄积量、资源重要性指数未必就高,如鲁山县等;(2)单位蓄积量高的区县,资源重要性指数也较高,但并非完全一致,不一致的如郏县等;(3)综合了资源数量和质量的重要性指数能较好地诠释森林质量的优劣,特别是在某一区域范围内。该研究可为栎类资源可持续经营利用提供依据和参考。As the one of the one of the importance forest resources,the oak forests resource is owned many values in economic and ecological aspect,and its realization were directly affected by forest quality.Based on forest resource inventory data for management of Henan province,the article evaluated the oak forests quality of most of counties in mountainous region of Henan province from three indexes:resource quantity,forest volume per hectare,and significance index(SI)of forest resource.The result is shown:(1)counties that the oak resource quantity is more,its forest volume per unit and SI were not necessarily higher such as Lushan county;(2)counties that the forest volume per unit is higher,its SI is also higher in proportion,but it is not completely consistent,such as Jiaxian county;(3)the SI integrated with resource quantity and forest volume can better illuminate the forest quality,especially in a region-level area.The research will provide a reliable basis for sustainable forest management and utilization.
