中文摘要	为了定量研究土地盐渍化时空变化影响因子的相对影响力大小，以典型干旱区中国新疆渭干河灌区为例，基于现阶段土地盐渍化研究成果，在8个不同的空间尺度下，分别选取了7个土地盐渍化时空变化影响因子，应用灰色关联方法分析了各个影响因子在土地盐渍化时空变化过程中的相对影响力大小。研究结果表明自然和人为因素共同作用于研究区土地盐渍化时空变化过程，而对土地覆盖／利用变化作用的人类活动在研究时间段内起主导作用，地下水埋深、地下水矿化度和气候因素在较小尺度上起主要作用，地形地貌、灌排系统、地表水资源在较大尺度上起主要作用。在每个空间尺度上各个影响因子的影响力相差不大，研究区土地盐渍化变化影响因素复杂，其治理等工作需要综合考虑各个因素的作用。
英文摘要	In order to study the driving forces of land salinization tempo-spatial change quantitively. The Weigan River Irrigated Area at the north of the Tarim Basin of Xinjiang, China, an typical arid area, was selected as an example for the study. Based on the current study results of land salinization, seven driving forces of tempo-spatial change of land salinization was selected respectively at eight different spatial scale, then the gray association degree between driving forces and soil salinization process at eight scale were calculated. Based on the statistic results, the paper found that every selected driving forces has different association degree with land salinization process at different scale, the natural and human driving forces act on the tempo-spatial change process in the study area at the same time, and the human activity is the main driving force in the study stage. The groundwater buries depths, groundwater mineralization degree and climate are the main control forces at smaller scale, and the terrain, irrigation and drainage system, surface water are the main control forces at larger scale. The power of every driving force has little difference at the same spatial scale. The driving forces of land salinization tempo-spatial change are complicated, the management and control of land salinization in the study area should consider the effect of every driving force integrated. The method used in this paper can be applied to analyzing driving forces of land salinization process quantitively, using this method can also avoid subjectivity and blindness as selecting driving forces to study land salinization.
