Abstract

In order to get the information of soil moisture change caused by human activities, the influence of the regional dynamic change of land use on soil moisture level was analyzed in this paper. Firstly, the graphs of land use type in two phases were worked out with remote sensing images (collected on 1987-05-07 and 2000-05-02, respectively). On the other hand, the soil moisture in the two days was correspondingly achieved by using the NDVI-LST feature space. Comparing the soil moisture change with the land use change, we can conclude that there was great correlation between changes in the soil moisture and changes in land use. But as the factors which can affect the soil moisture are various, the situation in some areas came up as inconsistent with the common sense which is worth to do some further studies. Besides, with the transforming of saline-alkalized land in this region, not only the cultivated area was increased, but also the vegetation degree of land coverage and the soil moisture level in most regions were enhanced, and moreover the ecological environment was improved.
