摘要
利用黄河上游宁蒙灌区近 5 0年气温、降水资料 ,分析揭示了气候干暖化的趋势 ,根据气温、降水和灌溉面积与耗水量的关系 ,建立了气候因素和灌溉面积等其他因素与耗水量的关系式 ,计算分析了近 2
Aridification tendency in Ningmeng irrigation area of the upper Yellow River is analyzed with the datum of air temperature and precipitation in the last 50 years in the paper. And then, the calculation formula of water consumption is established based on the relativity analysis of water consumption and air temperature, precipitation, and irrigation area. And last, the effects of the climate and other factors variation on water consumption in the last 20 years was calculated with the water consumption formula.
