Safe drinking water is directly related to people’s health and quality of life, and it ismajor issues related to people’s livelihood.The Ulan Buh Desert Basin is a typical continentalarid climate, scarce rainfall, strong evaporation, no surface runoff, and living and productionwater mainly are from groundwater. Due to the rapid development of the region of jilantai saltindustry and oasis agriculture, a lot of exploitation of groundwater, leading to the rapiddecline in groundwater levels, poor water quality and other issues, a serious impact on thehealth of farmers and herdsmen. This article relies SEE Ecological Association fundedprojects-Ulan Buh Desert and its ecological effect of groundwater resources, through fieldsurveys, data collection, literature review, and regional characteristics analyzes were carriedout Ulan Buh Desert Basin agricultural and pastoral areas of drinking water safety assessmentand protection countermeasures aimed at improving farmers and herdsmen’s drinking watersafety levels and pastoral areas of desert basins safeguards drinking water safety orientationprovides a scientific basis and technical support. The main results are as follows:(1) The Ulan Buh Desert groundwater system is divided into piedmont alluvial andeolian pore water, lacustrine basin, lacustrine and eolian pore water, pore water3YellowRiver alluvial groundwater resource calculation area.Among them, piedmont alluvial andeolian pore water, lacustrine basin, lacustrine and eolian pore water basin hydrogeologicalunits belonging Jilantai is subject Ulan Buh Desert. Jilantai groundwater resource levelingresults showed that: the average years diving and excretion of natural recharge negativeequilibrium, the relative equilibrium difference reaches1.98%, expressed as groundwaterlevels continued to decline, a direct threat to drinking water safety.(2) This article has established a multi-level drinking water security evaluation indexsystem by the target layer, guidelines and index. Quantity, water quality and water supplythree criteria layer is selected, and I select10evaluations: the proportion of the population ofwater security, per capita water consumption, the proportion of the population of the excessfluorine, the proportion of the population of arsenic exceeded, the proportion of peopledrinking brackish water, water purification facilities penetration, other groundwater quality proportion of the population, the rate of water security, water penetration and waterinconvenient population ratio.(3) Five towns(Sumu) in the Ulan Buh Desert Basin evaluation of the safety of drinkingwater to be showed that: Quantities, which the Zongbieli town level is unsafe, the remainingfour towns as the basic safety; Water quality, Aolunbulage town is very unsafe, Jilantai townas unsafe level, Zongbieli town、the Wusitai town and hematoxylin Bayan Muren basic safety;Water supply, five towns have as a basic level of security; Integrated aspect, drinking water ofthe Aolunbulage town is unsafe, and the other four towns are for basic safety.(4) For the evaluation results, I analyze the causes and propose measures to protect thedrinking water security from water security, water purification technology and other aspectsof the drinking water system.
