| Abstract: |
| By using 3S technology and supervised classification method, the Landsat-TM remote sensing images of Weigan-Kuqa oasis in 1989 and 2010 were statistically analyzed so as to obtain the quantitative statistic data and vector graphics on land use and land cover change (LUCC). Furthermore, the
relation between land use change and water resource was investigated according to the exploitation of land surface runoff and groundwater resource, agricultural planting structure, urban water consumption and ecological vegetation water consumption. The results showed that: the arable land in the study area increased year by year, which was expanded by 141 573.4 hm2 in 22 years, or 6 741.59 hm2·a-1 in average; the woodland and grassland decreased drastic
ally at the rate of 7 682.38 hm2·a-1; the urban water consumption incre
ased from 0.41×108 m3 to 4.26×108 m3, and the number of electromechanical wells increased rapidly, causing serious ecological problems in the downstream such as the falling of water tables, the increasing of water salinity and the reduction of natural vegetation. |
