| 摘 要： | 在广泛搜集资料和实地土壤采样调查的基础上,系统分析人为干扰下松嫩平原水盐运动规律及土壤盐渍化过程。利用灰色关联分析方法对该区50年的资料进行定量分析,探讨人为因素引起的松嫩平原水土环境的空间结构变化与土壤盐渍化的耦合关系。研究结果表明植被退化和流域内流化是松嫩平原盐渍化形成与演化的直接原因;短时期内人为因素对土壤盐渍化面积变化影响显著,其贡献率大于气候因子变化对盐渍化面积的影响。

| Abstract: | Based on the abroad collected data and study of soil sampling , the rule of water -salt movement in Songnen Plain and the process of soil Saline -alkali were analyzed fully . Using the method of Grey Incidence Analysis , quantitative analysis of 50 years' data of this region was disposed, the coupling relation between the change of soil&water environmental and spatial structure and soil saline -alkali Evoking by human activies were discussed. The results showed that vegetation deterioration and inner flowing of drainage basin were the direct cause of Songnen Plain' saline -alkali ,the effect of human activities on the expanding area of soil saline -alkali rising was greater than that of climate factors at a short period. |
