高标准基本农田整理项目水资源平衡分析——以察汗乌苏河流域为例

以青海省都兰县察汗乌苏河流域高标准基本农田整理项目为例,结合研究区域水文调查、社会经济资料对研究区供水量与需水量进行综合分析及预测,探究水资源供水量能否完全满足耕种要求。按照当地种植习惯,根据该区域综合灌水定额以及作物生长特点和灌溉制度,结合节水灌溉措施,讨论了水资源平衡分析的要点和方法,计算得出该区域可供水量和项目实施后的农业灌溉需水量,为项目规划设计提供参考。

Analysis of Chahanwusu River Basin High Standard Basic Farmland Consolidation Project of Soil and Water Resources

Taking Dulan county of Qinghai province Chahanwusu River Basin high standard basic farmland consolidation pro-ject as an example, based on regional hydrological survey, social economic data were analyzed in the study area, water sup-ply and water demand prediction, determine whether the water resources in the area of water supply could fully meet the re-quirements of farming and planting habits, according to local. According to the regional comprehensive irrigation quota and crop growth characteristics and irrigation system, combining with the water-saving irrigation measures of water resources bal-ance points and analysis method were introduced. The research of the region were calculated for the water to meet the project after the implementation of the agricultural irrigation water demand, which provided the technical foundation for project plan-ning and design.
