英文摘要 | Aerial photographs taken in 1978 and 1987, landsat tm images in 1998 as well as soil, hydrology and socio-economic data for the oases in sangong river watershed were processed by remote sensing (rs) and geographic information system (gis). there are two typical agricultural land uses in oases, farm-based land use with large-scale intensified agricultural activities (flu) and household responsibility-based land use with small-scale activities (hrlu). the index model of land use/land cover change (lucc), weighted index sum (wis) and logistic stepwise regression model were established to contrast the two typical lucc processes and their driving forces. the land use patterns were dominated by cropland and grassland for the entire region, and cropland, residential and industrial land were increasing stably. in the hrlu areas, woodland and grassland declined dramatically, but in the flu areas, grassland decreased only by 12.0%, whereas woodland increased by 13.7%. lucc was stronger in the earlier stage (1978-1987) than in the later stage (1987-1998) for the entire region. lucc was more intense in the hrlu areas than in the flu areas during the entire period (1978-1998). policy was a key factor in the land use change, and water resources were a precondition in land use. under the control of policy and water resources, the main human driving factors included population and economy, and the main natural restrictions were soil fertility and groundwater depth. human driving factors controlled the land change in the hrlu areas, but natural restriction factors dominated in the flu areas. in the mean time, intensification of lucc in the region had some spatiotemporal implications with a fluctuation of impact factors. |
