| 摘 要： | 以TM影像为数据源,动态监测了延安市宝窄塔区1997,2004年的土地利用、土壤侵蚀的时空变化,并对该变化进行了分析.结果表明,宝塔区土壤侵蚀主要发生在耕地、林地、草地、果园这4种土地利用类型中;1997-2004年期间,宝塔区耕地面积人幅减少,林地、草地面积有所增加,土壤侵蚀面积减少,侵蚀等级下降.总体上来说,延安市土地利用和土壤侵蚀状况都是向良性循环发展的.

| Abstract: | In order to dynamically monitor soil erosion and determine the relationship between landuse and soil erosion in Baota District of Yan'an City,an analysis was performed using the data from TM images in the two periods of 1997 and 2004.Results show that soil erosion occurred in cultivated land,forestland,grassland,and orchard.The area of cultivated land decreased and the areas of woodland,grassland,and orchard increased from 1997 to 2004.The area of soil erosion decreased and its grade descended.Generally spe... |
