通过利用Terra/Aqua卫星上搭载的MODIS传感器计算获取的16d合成植被指数产品(MOD13A2),进一步按照最大值合成法计算月合成光谱植被指数,按照USLE模型月模式评价江西省2005年土壤侵蚀,并与传统的USLE模型年模式计算的结果进行了比较。 更多还原

【Abstract】 Rich of quaternary red soil with sticky clay,low water permeability and abundant precipitation caused soil erosion extensive in Jiangxi Province.USLE have been used in evaluating soil erosion for several decades with a multiplication formula by 5 parameters characterizing annual erosion power of precipitation,annual vegetation factor,topography,measure of land management and Soil erodibility respectively.Considering that most of precipitation happened during from May to August in Jiangxi Provinc... 更多还原
