本文论证了所研究地区农业可持续发展中尚需解决水资源紧缺、土壤存在潜在盐渍化威胁和土壤肥力不高等主要问题。欲达此目的，应走农牧结合培育肥土的道路。具体方案是充分利用农作物秸秆发展草食牲畜，增加优质有机肥源；节约大量粮食，增加动物性蛋白供应量；充分利用植物资源，减轻环境污染和增加农民收入。 This paper demonstrates that the main problems of water shortage, potential soil salinization and low soil fertility need to be solved in the sustainable development of agriculture in the studied area. To achieve this goal, we should take the road of cultivating soil and fat with the combination of agriculture and animal husbandry. The specific plan is to make full use of crop straw to develop herbivorous livestock and increase the source of high quality organic fertilizers; to save a large amount of grain and increase the supply of animal protein; to make full use of plant resources, reduce environmental pollution and increase farmers’ income.
