| 摘 要： | 新疆地区土地盐碱化危害严重,造成生产能力下降。通过同一时段对和田地区不同盐碱地地貌(未开垦的荒平地、荒坡地、荒低洼地以及使用3年的熟平地)的实地考察和测试研究,获得水盐分布现场数据。分析造成不同盐碱地地貌水盐分布差异的原因,结果表明:土壤含水量高低次序为:荒低洼地>使用3年熟平地>荒平地>荒坡地,土壤含盐量高低次序为:荒低洼地>荒平地>荒坡地>使用3年熟平地,未开垦盐碱地地貌土壤含盐量与土壤含水量呈正相关。

Study on the Water-salt Distribution Discrepancy in the Different Saline and Alkaline Lands of Hetian Region in Xinjiang |

| Abstract: | Land salinization has been seriously harming Xinjiang region which caused decline in production capacity. At the same period of time, fieldwork research and testing were made in different saline and alkaline land(uncultivated barren flatlands,barren slope-lands、barren lowlands and using-flatland which has been used three years)of Hetian region,which obtained the field data of water-salt distribution.Analyzing the reasons of water-salt distribution discrepancy in different saline and alkaline lands.The results showed that the soil water content level order :barren lowlands > using-flatlands >barren flatlands >barren slope-lands,the soil salt content level order:barren lowlands >barren flatlands >barren slope-lands >usingflatlands and the salt content had positively correlation with water content in the uncultivated lands |
