摘  要:
利用不同时期福建省的土壤侵蚀数据,对闽南地区土壤侵蚀的时空变化进行分析。分析结果表明,闽南地区是福建省土壤侵蚀最严重的地区,区域内侵蚀最严重的局部位于东南低丘平原区;在空间分布上,土壤侵蚀呈现出20世纪80年代由东南低丘平原区向西北丘陵山地区减缓,而90年代呈相反的规律;在时间变化上,土壤侵蚀总体呈下降趋势,且东南低丘平原区的降幅远大于全区平均值,而西北丘陵山地区则呈现出在20世纪80年代至90年代中期上升而后有所下降的趋势。

摘  要:
Through soil erosion data of-diffenrent period in Fujian Province,spatio-temporal variation of soil erosion in the south Fujian were disscussed. The result showed that the south Pujian, in which the serious erosion area lain in the south-east foothill-plain area, was the most serious erosion area in Fujian Province. The spatial distribution of soil erosion abided by the law that soil erosion lightened from the south-east foothill-plain to the north-west upland-mountain area in 1980's, the opposite way round in 1990's. The temporal variation of soil erosion indicated that soil erosion decsended in general, especially in the south-east foothill-plain, while soil erosion in the north-west upland-mountain area asended from 1980's to the middle of 1990's and descended after the middle of 1990's.
