沙型盐碱地水产养殖生态修复效果评价

Ecological Restoration of Sandy Saline-sodic Land by Aquaculture Technology:An Effect Evaluation

为修复西北地区沙型盐碱地的土壤环境,提升盐碱土地的利用效率,以景泰县盐碱地区为试验区域,创新采用水产养殖生态修复技术,并综合评价了该技术的修复效果。结果表明:采用水产养殖生态修复技术后盐碱地区的盐度,氯化物和硫酸盐等指标呈现逐渐下降趋势,改善了当地的土壤环境,提升了盐碱土地的利用效率。发展水产养殖业也给养殖户带来了一定的经济收益,提升了养殖户发展水产养殖业的积极性,起到了良性发展的效果。本文为盐碱土地的修复治理提供一种高效生态的修复方法,并为全国盐碱地的改良提供一定的技术参考。

To restore soil environment and improve the utilization efficiency of saline-alkali land in northwest China, the ecological restoration technology of aquaculture was adopted in the saline and alkali area of Jingtai County, and its effect was evaluated comprehensively. The results showed that after using aquaculture ecological restoration technology, the indexes such as salinity, chloride and sulphate of the saline area decreased gradually, which improved the local soil environment and elevated the efficiency of saline land utilization. The development of aquaculture brought certain economic benefits to the farmers, and raised the enthusiasm of the farmers for the aquaculture industry. This paper provides an efficient ecological restoration method for the restoration of saline soil, and some technical references for the improvement of saline-alkali land in China.
