摘　　要：在对河岸带特性进行调查的基础上,针对我国北方河岸带的特点,提出了从植被结构完整性和河岸结构稳定性两方面的14个指标组成的河岸带植被结构和功能评价体系,对山西省沁河的一级支流赤石桥河和紫红河的河岸带植被进行了评价;同时进行河岸缓冲带恢复重建试验,研究了不同恢复措施下纯草、乱石滩、纯灌三种沁河上游河岸带典型地块的植被恢复效果,以期为我国北方河岸植被缓冲带的构建、修复和管理提供参考。To rehabilitate and reconstruct the riparian vegetation buffer strips on the upper reaches of the Qin River in Shanxi Province of China,the field survey and experiments were conducted to provide an example of constructing forest riparian vegetation buffer strips in the region.An assessment index system was used to evaluate the Chishiqiao and Zihong rivers,both first-level tributaries of the Qin River.A comprehensive evaluation index system offered indicators of vegetation structural intactness and stability including 14 indicators.To improve vegetation coverage,abundance,and collocation forms,we chose typical riparian vegetation zones,including grassland,shrub land,and shrub-grass land,and implemented different treatments,i.e.fencing the vegetation zones,planting grasses or shrubs,and covering with soil and turf.We found that soil hygroscopic coefficient,soil fertility,and total nitrogen content were strongly enhanced.Certain types of riparian buffer strips that would be suitable in this region are suggested.
