中文摘要	[目的]探讨沙漠化地区地下水位的分布状况及其对沙漠植被的影响,为塔里木河流域生态环境保护提供科学依据。[方法]利用MODIS卫星遥感数据,采用遥感数学模型学融合的研究方法,在实地考察塔里木河中游区域的地下水位、土壤水分和其他辅助资料的基础上,通过建立土壤水分和地下水位的线性方程,提出在土壤中存在毛细管补给条件时,简便、有效地监测沙漠化地区地下水埋深的监测模型,并在塔河中游沙漠化地区进行实地验证。[结果]该模型反演地下水位和实测地下水位之间的相关系数为0.896 9,误差较小。研究结果符合实际。[结论]在较大范围且地下水埋深不大于6m的沙漠化地区,利用MODIS多波段遥感模型监测并评价地下水位埋深的空间分布是可行的。
英文摘要	[Objective]In order to provide the theoretical basis for protecting the ecological environment of Tarim River Basin,the spatial distribution of groundwater level and its effects on vegetation in Aeolian desertification areas was explored.[Methods]MODIS satellite remote sensing image data and combined method of remote sensing-mathematical-model were used.Field investigations of groundwater level,soil moisture,and other relevant information in desertification area in the middle reaches of Tarim River in Xinjiang Uygur Autonomous region were measured.Through the empirical model fitting between the measured soil moisture as independent variable and groundwater level as dependent variable,under the prerequisite condition when there is capillary supply in soil,a simple and effective remote sensing method was proposed,and it was verified that can be used to evaluate the distribution of groundwater level based on the MODIS image data. [Results]The correlation coefficient of the measured groundwater and the remote sensing retrieved water level was 0.896 9,and the error was small.The result proved that the model is applicable.[Conclusion] When groundwater depth is not more than 6m,it is feasible to use MODIS multi band remote sensing data to monitor and evaluate the groundwater level and its spatial distribution in the desertification area.
