摘要

通过对不同开垦年限土壤剖面盐分调查

进行北疆典型残余盐土的变化特征研究。以玛纳斯河流域包家店镇典型地块为研究区

运用统计学和空间置换时间相结合的方法探讨土壤盐分的动态变化及其影响因素。结果表明

随着开垦年限的延长土壤剖面盐分均呈现相对减少的趋势

8年后土壤剖面的平均盐分降低到4g/kg左右

年均脱盐率达到10.6%;该残余盐土区域土壤剖面盐分主要聚集在中底层(30-100cm)

呈底聚型;开垦6年后土壤盐分的活跃范围集中在0-60cm;开垦年限影响土壤盐分的同时土壤质地也是影响土壤盐分大小的重要因素。该研究结果将对残余盐土的发生演变及改良培肥提供科学依据。

Abstract

Change characteristic of the typical residual solonchak in the northern of Xinjiang were explored

through investigating soil profile salt on different reclaimed years.Baojiadian town in the mamas' river watershed was considered as research area

researching dynamic change of soil salinity and its influencing factors by using methods of traditional statistical and temporal-spatial conversion.The results showed that the salinity of soil profile

with the extension of reclaimed years

was significantly decreasing...
