摘要
以1995年,2000年2个时段的土地利用和土壤侵蚀TM影像数据为基础,采用GIS空间分析方法和马尔科夫模型对海伦市土地利用和土壤侵蚀变化进行了综合分析。分析表明,土壤轻度、中度侵蚀以旱田为主,强度侵蚀主要是坡耕地。海伦市1995年土壤侵蚀强度大于2000年,从土地利用和土壤侵蚀整体发展趋势来看是向着良性循环转化。
In order to investigate soil erosion conditions and relationship between soil erosion and landuse in Hailun County, an analysis was performed based on GIS using the data of TM images in 2 different periods of 1995 and 2000. Results showed that dry farm land was the main eroded land type with light and moderate erosion degrees, and slope land was the main type of landuse with an intense erosion degree. Soil erosion rate in 2000 was reduced compared with that in 1995. A good trend was observed after soil and water conservation was implemented in the study region.
