宝鸡峡灌区耗水量变化规律及影响因素分析研究
- Title:
- Study on Water Consumption Change Rule and Influence Factor in Guanzhong Irrigation Area
- 分类号:
- S274.2
- 摘要:
- 综合目前各种耗水量的概念或定义，从关中灌区水资源形成及转化的角度出发，并考虑到灌区以农业灌溉为主，兼有其他行业供水、用水、耗水及排水为一体的特点，界定了灌区耗水量的概念。通过对灌区用水对象和耗水机理的分析，建立了灌区耗水量计算模型。通过模型计算与分析，表明农业用水耗水量是宝鸡峡灌区的耗水大户；灌区1991-2003年耗水量总体呈小幅度递减趋势，与农业用水耗水量的变化趋势一致，而工副业、城市及农村生活用水耗水量呈线性递增的趋势，灌区农业用水耗水量的变化支配着总耗水量的变化。
- Abstract:
- This article synthesized each kind of water consumption concept or definition at present and defined the irrigation area water consumption concept.Through analysis of irrigation area water use object and water consumption mechanism analysis, the bigger one established the irrigation area water consumption computation model.Through model computation and analysis, indicated the agricultural water consumption is the bigger one in the Baojixia irrigation area.The irrigation area in 1991-2003 water consumption overall assume the small scope degression tendency, is consistent with the agricultural water used-consumption change tendency.But the industrial occupation and the city and the village life water use assumes the tendency which the linearity increases progressively.The irrigation area agriculture water consumption change is contribute to the total water consumption change.
