摘　　要：以荒地为参照,采用定位研究的方法对黑龙江省东部地区的榛子天然灌丛林的水文生态特征进行了系统研究,结果表明:灌丛能够有效地改善土壤结构和孔隙状况,地上部分最大持水量可达50.30 t.hm-2,土壤最大蓄水量和有效持水量分别为3 402.84 t.hm-2和315.76 t.hm-2。土壤渗透性能明显优于荒地,初渗、稳渗速率和到达稳渗时间都显著提高,显示出灌丛植被在当地水源涵养型植被构建体系中具有重要地位。Based on principle of located research, we studied the hydrological function of wilderness and Corylua spp. in eastern of Heilongjiang province. The results showed that Corylus spp. could improve soil structure and the condition of soil porosity effectively, the maximum moisture capacity of the aboveground is 50.30 t · hm^-2 , the maximum pondage and usable capacity are 3 402.84 t · hm^-2 and 315.76t · hm^-2. The soil permeability enhance remarkably than wilderness. The initial infiltration rate, stable infiltration rate and period of time to stable infiltration have a remarkable improvement. Scrub vegetation plays an important role in the conformation of the type of water conservation vegetation in this region.
