摘　　要：以无资料的北洛河入陕省界控制断面入境生态需水量的推求为例。根据北洛河及其较大入境支流葫芦河张村驿水文站,以及省界断面水文站规划情况,分析选择葫芦河无资料区域入陕控制断面需要考虑的因素,得出选用规划的杨家湾水文站作为北洛河入陕控制断面是合理的;采用地区经验公式与面积比拟计算杨家湾断面非汛期生态需水量,结果表明:杨家湾控制断面年生态需水量为3320万m3,非汛期生态基流为0.30 m3/s,其结果较为合理,可供水资源有关部门在水资源管理中参考或使用。Take the calculation of the inbound ecological water demand of the Beiluo River with no data into the control section of Shaanxi Province as an example,according to the Beiluo River and its large-scale tributary,the Zhangcun Hydrology Station of the Hulu River and the planning of the hydrological station of the provincial boundary section,the factors that need to be considered in selecting the Hulu River non-data area into the Shaanxi control section are analyzed.Bay Hydrological Station is reasonable as the control section of Beiluo River into Shaanxi.The regional ecological formula is used to calculate the ecological water demand of the Yangjiawan section in non-flood period.The results show that the annual ecological water requirement of Yangjiawan control section is 33.2 million m^3.The ecological base flow in the non-flood period is 0.30m^3/s,and the results are reasonable.It can be used or referenced by water resources management departments in water resources management.
