福建省水土流失的时空变化
Temporal and Spatial Variation of Soil Erosion in Fujian Province
摘要
Abstract
[Objective] To provide scientific basis for soil and water conservation,the dynamic monitoring and temporal and spatial variations of soil erosion in Fujian Province from 1990 to 2015 were studied.[Methods] Choosing Fujian Province as a study area,combined with GIS and RS technologies,the research was carried out based on USLE model.[Results] ① The soil erosion intensity of Fujian Province was general light.The soil erosion areas were found primarily in the western and southeastern of Fujian Province and less in central and northern parts,As to the spatial variation of soil erosion,a decreasing trend from the southeast coastal area to the northwest inland area was found existed.During the past 25 years,the transfer of soil erosion intensity mainly occurred between the light/moderate erosion and slight erosion.② From 1990 to 2015,the area of soil erosion reduced by 3 825.55 km2 totally,which was mainly covered by light erosion intensity.Especially after 2010,the area of soil erosion showed a faster shrink.Meanwhile,soil erosion in coastal areas got improvement more evidently than the erosion in inland areas.[Conclusion] The improvement of soil erosion in Fujian Province was obvious during the past 25 years,which showed significant benefits in soil erosion control,关键词
