| 摘要: |
| 土壤盐碱化不仅导致土壤生产力降低，而且引发诸多生态环境问题。新疆受不同程度盐碱危害的耕地面积约占新疆耕地总面积的1/3，盐碱化已经成为新疆农业开发和持续发展的重大限制条件和障碍因素。随着土地资源的紧张，必须寻求有效措施防治和改良盐碱土壤。文章主要阐述了新疆盐碱地的现状与分布，并根据国内外研究进展，回顾与分析了新疆盐碱地的成因与改良技术发展状况，最后对今后需进一步研究的问题进行了展望。 |

| Salinization causes and research progress of technologies improving saline-alkali soil in Xinjiang |

| Abstract: |
| Soil salinization not only reduced soil productivity,but also led to many eco-environmental problems.Xinjiang′s arable land affected by various degrees of salinity hazard takes up about 1/3 of the total cultivated land,and soil salinization has become the major constraints and obstacles of agricultural development and sustainable development in Xinjiang.With the tension of the land resources,we must find effective measures to control and improve saline-alkali soils.Accordingly,based on relevant research advances,the paper reviewed the formation of saline alkali soil in Xinjiang and development of the improvement technologies,described the status quo and distribution of saline-alkali land in Xinjiang,and recommended the further research areas in the future. |
