Abstract

The changing process of Guangxi farmland resource in recent 20 years was analyzed via 5 periods of land use data abstracted by remote sensing technique in this paper; farmland potential productivity was estimated and influence of LUCC process on farmland potential productivity was analyzed by combining with daily meteorological data from 1990 to 2010 and adopting environmental factor successive correction model. According to the remote sensing monitoring result, Guangxi farmland area was decreased by 20,843.81hm2 in recent 20 years. Under average climate conditions from 1990 to 2010, farmland change has made the mean value of farmland potential productivity in Guangxi an accelerated decline trend. The mean value of farmland potential productivity for reclaimed farmland was 6,013.44Kg/hm2, and that for lost farmland was 11,408.11Kg/hm2, so the quality of reclaimed farmland cannot catch up with that of lost farmland. In all farmland changes, the dynamic type of turning forest into farmland contributes the most to the increase of gross farmland potential productivity, occupying 80.73% of total value for reclaimed farmland; the dynamic type of turning farmland into construction land decreased gross farmland potential productivity by the most, occupying 74.39% of total value for lost farmland.
