| 英文摘要 | Based on tupu theory, this paper studied the,dynamic changes, conversion modes, expansion intensity and landscape attributes of the saline-alkali lands in changling county, zhenlai county and da'an city of the western jilin province in 1980-2000 with the help of gis. the results show that the saline-alkali land rather sharply increased in da'an during 1995-2000; the main conversion processes in the three counties were from grassland to saline-alkali land and from saline-alkali land to grassland; and the typical shapes, spatial expansion speed and mode, and landscape attributes of the saline-alkali land were different in the three counties, which were closely related to local topography, predominant wind orientation, water resources distribution, etc. the corresponding spatial expansion mode was marginality in changling, random in zhenlai and more kernels in da'an, respectively. landscape attributes also responded to the spatial-temporal dynamic changes of the saline-alkali land and the landscape indices of da'an fluctuated greatly. the frame of this research may provide fundamental reference for landscape analysis and give some suggestions for regional sustainable development. |
