摘要
在总结已有研究成果及实践经验的基础上,结合近期开展的水盐监测与试验研究,综合地下水开发利用、节水节肥、土地资源合理配置以及农业结构调整等成果资料。应用土壤水盐运移理论与系统分析原理,为实现干旱内陆河流域水土资源可持续利用,系统地提出适应于不同地貌单元,不同土壤盐碱化治理阶段的竖井排灌、竖井与水平联合排灌、水平排水等工程措施,以及利用自然与人造微地形情况下的农田干排盐、生物排盐措施。
Soil salinization is a global problem in agricultural development. The area of croplands with secondary salinization of soil in Xinjiang is as large as 8.29 × 10^5 hm^2 and occupies 21.9% of the total cropland area. Because of the infrequent precipitation ad violent evaporation in arid areas in Xinjiang, irrigation is the main and even only way of developing agriculture, and secondary salinization of soil occurs easily in large area due to the irrational irrigation. Based on the practical experience and the recently monitored and tested results of water and salt transfer in soil, this paper summarizes the scientific research achievements in the aspects of groundwater exploitation and utilization, irrigation and fertilization in saving way, rational exploitation of land resources, regulation of agricultural structure, etc. some irrigation and drainage measures, such as well irrigation and drainage, well - ditch irrigation and drainage and ditch drainage, are systematically put forward based on the theory of water and salt transfer in soil and the principles of system analysis so as to achieve.the sustainable utilization of water and land resources in arid contihental river basins. The measures are applicable under the conditions of different morphologic units and different stages of improving salinized or alkalinized soil, and also applicable in dry desalinization and biological desalinization of soil.
