中文摘要:
      以于田绿洲为研究区,借助 ENVI 5.1、ArcMap 10.2、Origin 8.5、SPSS 20.0,同时结合野外实测数据,对盐渍土不同土层(0 ~ 20、20 ~ 40、40 ~ 60、60 ~ 80、80 ~ 100 cm)的土壤含水量、温度、电导率的变化规律及相关性进行了研究。结果表明:研究区土壤含水量、温度、电导率从6月到8月呈升高趋势,绿洲南部和北部地区的5、8号点在60 ~ 80、80 ~ 100 cm土层的土壤含水量最高,8、22号点表层(0 ~ 20 cm)土壤电导率最高,而南部和西部地区的5、22号点在40 ~ 60 cm土层的土壤电导率最高;秋季和夏季的土壤含水量、温度、电导率均高于冬季和春季。研究区西部的16、22号点各土层的含水量与电导率呈显著正相关,60 ~ 80 cm土层土壤含水量与电导率的相关性最强,相关系数分别为0.970**、0.987**。通过对盐渍土不同土层的水分、盐分、温度的变化规律及相关性进行分析,有利于快速诊断土壤盐渍化,为掌握研究区土壤水盐状况以及土壤水盐动态研究提供了理论基础,为干旱区绿洲生态环境保护和农业可持续发展提供科学依据。
Abstract:
      This paper quantitatively analyzed the seasonal variation and correlation of saline soil water, salt and temperature in Yutian Oasis, located in southern Tarim Basin of Xinjiang by using ENVI 5.1, ArcMap10.2, Origin 8.5 and SPSS 20.0 software and the measured data of soil water contents, electrical conductivities and temperatures in different layers of soil profiles in different sites. The results showed that soil water contents, temperatures and electrical conductivities in all layers of all soil profiles increased gradually from June to August. Water content was highest in 60 ~ 100 cm layers in No.5 and No.8 sampling sites. Electrical conductivities were highest in 0—20 cm layers in No.8 and No. 22 sampling sites and in 40~60 cm layers in No.5 and NO.22 sampling sites. Water contents, temperatures and electrical conductivities in all layers of all soil profiles were higher in Autumn and Summer than in Winter and Spring. Soil water contents and electrical conductivities of No.16 and NO.22 sampling sites had significantly positive correlations, and the correlation coefficients were the highest in 60 ~ 80 cm layers, which were 0.970** and 0.987**, respectively. The above results indicate that the analyses on the seasonal variation and correlation of saline soil water, salt and temperature is helpful for the rapid diagnose of soil salinization, and they can provide the reference and guidance for the sustainable development of ecological environment and agriculture in Yutian Oasis.
