Completion of the project, together with those in 2008 before the implementation of the reconstruction project, Bayannur City Hetao irrigation area of 787 hectares of existing irrigation Yellow fundamental transformation will be completed, can add 50 million mu of cultivated area ; Yellow River Irrigation District water will be reduced by 1.2 billion cubic meters, equivalent to savings of 12 large reservoirs (according to the criteria for the classification reservoir, storage capacity up to 100 million cubic meters is large reservoirs); the annual grain production capacity can add three billion kg, close to irrigation district The current annual production of 3.8 billion kg of grain, and create a "granary north of the Great Wall."

项目完成后，连同2008年以前实施的改造项目，巴彦淖尔市河套灌区现有的787万亩引黄灌溉农田将基本改造完毕，可新增种植面积50万亩；灌区引黄水量将减少12亿立方米，相当于节省出12座大型水库(按水库划分标准，库容达1亿立方米就是大型水库)；每年可新增粮食生产能力30亿斤，接近灌区目前的粮食年产量38亿斤，再造一个"塞外粮仓"。

The research is about the reuse of urban sewage for virescence irrigation, and the influence of sewage irrigation on eco-environment such as soil, plant, etc. is studied. Under the condition of field sewage irrigation, the transport and transformation and accumulation mechanism of heavy metals, nutrients and organic pollutants as vaporizable hydroxybenzene etc. in the soil-plant system are analyzed. The heavy metal pollution is evaluated by the comprehensive pollution index. The spatial variability of heavy metals in sewage irrigation area is further understood. The spatial variability of heavy metals and physical and chemical properties of soil are reflected in a more straight way by the theory model of variance function curve based on the geographical information system.

在城市污水回用于绿化灌溉对土壤、植物等生态环境的影响研究中分析了大田条件下污灌对土壤-植物体系中重金属、养分及挥发酚等有机污染物迁移转化及富集机理，对重金属污染进行了综合污染指数评价，进一步了解了污灌区重金属分布的空间异质性，基于地理信息系统提出了变异函数曲线的理论模型，更直观地反映出了重金属元素与土壤理化参数的空间变异特征。

The results showed that : three species all can resistant to drought ,wind-drift sand and endure to sterile soil, and with fine adaptability to local condition that there are irrigation in growth phase and no irrigation in post-vegetative phase in 2002 and there are no irrigation in growing period and irrigation in after bearing phase in 2003. Among the three species ,Agropyron cristatum× A.desertorum cv.
