云南省区域代表站站网规划探讨

Study and Discussion on Planning of the Regional Hydrological Representative Station Network of Yunnan Province

区域代表站是流量站网中的重要组成部分,通过对规划区域代表站中的三种理论方法分析比较后,采用数理统计法中的递变率-内插法[1]对云南省第5水文分区进行了区域代表站站网规划,取得了对实际工作具有指导作用的成果。说明开展云南省区域代表站站网规划是非常必要的。为此我省应在保持现有流量站点的基础上,在经济可行、满足内插径流精度和产汇流分析的要求下相应增加区域代表站数量。

The regional hydrological representative nalysis and comparison of three theoretical methods station is an important integrant of the station network. After a- in planning of regional representative stations, the result that is of directive function to the practical work has been obtained through planning of regional representative station net- work of the 5th hydrological sub - region of Yunnan Province by the gradient interpolation method in the mathemati- cal statistics methods. It shows that it is badly necessary to carry out planning of the representative station network of Yunnan Province. Therefore the province shall appropriately increase the number of the regional hydrological rep- resentative stations on condition that it is economically feasible, the interpolation runoff precision and analysis of runoff and confluence can be satisfied based on preserving the existing flow gauging stations.
