- 摘要:
- 土壤盐渍化是影响区域生态环境稳定性以及制约农业生产发展的重要因素。以新疆典型盐渍化土壤—渭库绿洲为研究靶区,采用传统统计学方法,利用研究区7次不同采样时间和空间的土壤含盐量、pH及盐基离子等野外调查数据,对研究区土壤酸碱度、盐渍化类型及程度进行了分级。结果表明:渭库绿洲盐分有强烈表聚性,春季土壤含盐量大于秋季土壤含盐量,研究区盐渍化情况较严重,土壤含盐量往加重的方向发展;研究区土壤属于微碱性土,春季土壤碱化强于秋季;各层土壤盐渍化类型主要以氯化物硫酸盐型盐渍土和硫酸盐渍土为主,土壤中的氯化物在土壤剖面中呈自上而下减少的趋势,而硫化物呈自上而下增多的趋势。
- Abstract:
- Soil salinization is an important factor that affects regional ecological stability as well as restricts the development of agricultural production.The typical saline soil in Xinjiang—Ogan Kucha oasis was taken as study case,pH ,soil salinity types and degree were hierarchically divided using traditional statistical methods,making use of field investigation data sampled at seven different times such as soil salinity,pH and the salt ions,etc.The results showed that soil salt in the study area had the strong cohesion trend,the soil salinity in the spring was greater than in the autumn,soil salinization was quite serious,and soil salinity presented the trend of deterioration.Soil in the study area was slightly alkaline,and soil alkalinity in spring was stronger than that in the autumn; soil salinity types of each layer were mainly chloridesulfate and sulfuric acid saline soil.Soil chloride in soil profiles showed decreasing trend from top to bottom,while the minerals had increasing trend.
