以利用卫星遥感数据评价干旱区绿洲 荒漠交错带地下水位的分布作为主要研究目的 ,使用全波段Landsat 7ETM +图像 ,用遥感 数学 模型学融合的研究方法 ,在实地考察地下水位、土壤水分和其他辅助资料的基础上 ,建立土壤水分和地下水位的实验方程 ,提出了评价地下水位分布的遥感模型———GLDRS模型。利用GLDRS模型对新疆策勒绿洲 荒漠交错带进行了实地验证 ,结果表明 ,研究结果符合实际 ,GLDRS多波段模型优越单波段模型 ,理论地下水位和实测地下水位之间的相关系数为 0 90 1。
Using the satellite remote sensing data to evaluate the distribution of groundwater level in the oasis desert ecotone in arid regions, the Landsat 7 ETM + image of the entire band was used to study the groundwater level, soil moisture and other auxiliary Based on the data, the experimental equations of soil moisture and groundwater level are established. A GLDRS model is proposed to evaluate the groundwater level distribution. The GLDRS model was used to validate the ecotone in the Cele oasis desert region of Xinjiang. The results show that the results are in line with the actual, GLDRS multi-band model with superior single-band model. The correlation coefficient between the theoretical groundwater level and the measured groundwater level is 0 901.
