This research is composed of the following three subjects of study. (1) Water resources utilization for development of sandy deserts: in the experimental field at Shapotou Desert Experiment and Research Station, evapotranspiration from soybeans was estimated by the water balance method and the heat balance method under the condition of drip irrigation, and a possibility of agricultural utilization of treated wastewater from a rural settlement was discussed by the experiment of soybeans culture.2) Soil management for cultivation of sandy deserts: the physical and chemical properties of soil at Shapotou Station and at Naiman Desertification Rehabilitation Experiment and Research Station were investigated. The salt accumulation of sandy field by the surface irrigation of the yellow river water was not recognized. 3) Prevention of desertification for soil conservation of sandy deserts: In order to investigate desertification of the Horgin Sandy Land, the vegetation environment near the Naiman Station was monitored by utilization of remote sensing. The counterplan of prevention of desertification was discussed and the trend of desertification was forecasted by the analysis of the remote sensing data.

本研究由以下三个研究课题组成。(1)沙质荒漠开发中的水资源利用：在沙坡头沙漠试验研究站的试验田中，利用水分平衡法和热量平衡法估算了滴灌条件下大豆的蒸散量，并通过大豆栽培试验探讨了农村居民点污水农业利用的可能性。2)沙坡头试验站和奈曼荒漠化恢复试验研究站的土壤管理：对沙坡头试验站和奈曼沙漠化恢复试验站的土壤理化性质进行了调查。黄河水地面灌溉沙地积盐现象未被认识到。3)沙地水土保持防沙治沙：为调查霍尔金沙地荒漠化状况，利用遥感技术对奈曼站附近的植被环境进行了监测。通过对遥感数据的分析，探讨了防沙治沙的对策，并对荒漠化趋势进行了预测。
