【摘要】：對(duì)安固里淖干湖區(qū)的土壤粒度組成、含鹽量、含水量、有機(jī)質(zhì)和p H的空間分布特征進(jìn)行了研究。結(jié)果表明,湖區(qū)內(nèi)土壤主要以粉粒(0.002~0.05 mm)為主,湖區(qū)外圍土壤主要以粉粒(0.002~0.05 mm)、極細(xì)砂(0.05~0.1 mm)和細(xì)砂(0.1~0.25 mm)為主,湖區(qū)東部土壤比西部土壤質(zhì)地更細(xì)。土壤含水量由湖區(qū)內(nèi)部向外圍逐漸減小,但湖岸邊緣土壤含水量最高。研究區(qū)土壤鹽堿化現(xiàn)象明顯,含鹽量和p H都較高,湖區(qū)東部土壤含鹽量和p H都高于西部。研究區(qū)土壤有機(jī)質(zhì)含量總體偏低,與西部相比,干湖區(qū)東部土壤有機(jī)質(zhì)含量較高。研究區(qū)土壤含鹽量、含水量與p H顯著正相關(guān),有機(jī)質(zhì)含量與p H顯著負(fù)相關(guān)。
[Abstract]:The spatial distribution characteristics of soil granularity, salt content, water content, organic matter and pH were studied. In the lake area, the main soil is 0. 002 ~ 0. 05 mm), and in the peripheral soil of the lake area is 0. 002 ~ 0. 05 mm). Very fine sand (0. 05 ~ 0. 1 mm) and fine sand (0. 1 ~ 0. 25 mm) are dominant. The soil texture in the eastern part of the lake area is thinner than that in the west, and the soil moisture content decreases gradually from the inside to the periphery of the lake area. But the soil water content was the highest at the edge of the lake. The salinization of the soil in the study area was obvious, and the salt content and pH were both high. The soil salinity and pH in the eastern part of the lake area were higher than those in the western region. The content of soil organic matter in the study area was on the low side. Compared with the western region, the soil organic matter content in the eastern part of the dry lake region was higher than that in the western region. Water content was positively correlated with pH, and organic matter content was negatively correlated with pH.
