大安灌区是吉林省“十一五”期间重点规划的大型骨干灌区项目,该灌区的建成不仅提高了灌区内农民的人均收益,同时在调节区域气候、涵养水源、补充地下水以及防止沙漠化等多方面都贡献了重要的力量。然而大安灌区内盐渍化土壤的分布面积较大,土壤的盐碱化程度比较严重,造成了大安灌区内的水质恶化,对灌溉产生了重要的影响。本文在简析了大安灌区的自然环境状况的基础上,进一步分析了大安灌区土壤盐碱程度以及土壤改良与灌溉利用。
Da’an Irrigation District is a key backbone irrigation district key project planned during the “11th Five-Year Plan” in Jilin Province. The completion of this irrigation district not only increases per capita income of farmers in irrigation districts, but also regulates regional climate, conserves water, replenishes groundwater and prevents desertification Many aspects have contributed to the important strength. However, the distribution area of salinized soil in Daan Irrigation Area is relatively large, and the degree of salinization of soil is relatively serious, which leads to the deterioration of water quality in Daan Irrigation District and has an important influence on irrigation. Based on the analysis of the natural environment in Daan Irrigation District, this paper further analyzed the salinity level of soil and the improvement and irrigation of soil in Daan Irrigation District.
