| Abstract: | Based on multi-temporal remote sensing images of the Yellow River Delta acquired in 1984, 1986, 1989, 1992, 1995 and 1999, together with auxiliary data and geo-knowledge, oil fields concentrated area was delineated and land use elements were extracted. With the spatial analysis function of Geological Information System, land use changes in oil fields concentrated area from 1984 to 1999 were analyzed. The quantity of land use types and changes, and the spatial distribution of land use change in different periods were acquired. In the 15 years from 1984 to 1999, the area of oil fields increased from 245.7km2 to 799.69km2 and the density of wells increased too. The average annual increased rate was 8.18%, and the rate of increase was more rapid before 1989 than that after 1989. Before 1984, the oil fields were concentrated in the Kenli County, Dongying District to the south of the Yellow River and Hekou District to the north of the Yellow River. The newly developed oil fields concentrated area mainly lies to the Bohai Bay to the north of the Yellow River Delta,which leads to the main changes ranging from tidal flat to saline-alkaline land. Because of eco-environmentally extremely fragileness in the study area, the land use types changed frequently with higher proportion of the affected area. The main changes in oil fields concentrated area were conversions between shrub-grassland and saline-alkaline land. This study shows that it is possible to delineate the oil fields concentrated area and extract land use elements with remote sensing images and offer timely information for oil fields development and management. |
