【摘要】：了解阿克蘇河流域土壤侵蝕狀況是維護(hù)流域生態(tài)安全的關(guān)鍵。文章基于Landsat TM衛(wèi)星影像、土地利用數(shù)據(jù)、地形圖和植被覆蓋數(shù)據(jù),借助ENVI和Arc GIS軟件,針對阿克蘇河流域土壤侵蝕展開分析,結(jié)果表明:阿克蘇河流域土壤侵蝕強(qiáng)度上以輕度和中度侵蝕為主,分別占侵蝕總面積的27.77%、44.76%,侵蝕類型上以風(fēng)力侵蝕為主;2005-2013年間流域侵蝕區(qū)土地好轉(zhuǎn)面積1 381.2 km2,退化面積829.5 km2。阿克蘇河流域內(nèi)的土壤侵蝕情況總體在改善,但在局部地區(qū),土壤侵蝕仍有加劇現(xiàn)象。
[Abstract]:Understanding soil erosion in Aksu River basin is the key to maintain ecological security. Based on Landsat TM satellite image, land use data, topographic map and vegetation cover data, and with the aid of ENVI and Arc GIS software, the soil erosion in Aksu River Basin is analyzed. The results showed that the intensity of soil erosion in Aksu River Basin was mainly mild and moderate, accounting for 27.77% of the total erosion area, respectively, and the erosion type was mainly wind erosion. The area of land improvement was 1 381.2 km ~ 2 and the degraded area was 829.5 km ~ 2 between 2005 and 2013. Soil erosion in Aksu River basin is improving, but in some areas, soil erosion is still intensified.
