| 摘 要： | 以宝鸡峡灌区为例，分析了由于水土流失导致河流高含沙量对水资源利用产生的不利影响。对宝鸡峡灌区六个水库联合调节计算的结果表明:河流含沙量与宝鸡峡灌区水资源利用的影响关系，指出宝鸡峡灌区水资源利用最根本的问题是流域水土流失问题。解决问题根本出路在于加快渭河上游水土流失治理，减少河川径流含沙量。同时，提出通过沙限的合理选取提高灌区水资源的利用率的调节利用途径。

| Abstract: | It is discussed that soil and water loss affects water resource utilization in Baojixia irrigation system.Four points in the Wei River are selected to calculate the influence.The data can be obtained by combined regulation model of six reservoirs, which can demonstrated the influence of soil and water loss.All of the figures show that the utilization of the Wei River water resources would be affected by sediment.Finally, the optimal controlled sandiness capacity is obtained from the results of calculation, and the water resource utilization rate can be improved by the choosing of rational sandiness capacity.Therefore, a conclusion can be drawn that the most important problem in water resource utilization in Baojixia irrigation system is soil and water loss, which should be controlled effectively. |
