土壤流失总量 meaning in Chinese
gross soil loss
Examples
- Finishing quantitative remote sensing task on soil losses of 1998 and 1999 in study area . through running the pixel statistical program , we can obtain the results of soil erosion in the drainage basin - the total amount of soil losses of the experimental region were : 4 . 84 million tons in 1998 and 8 . 69 million tons in 1999 respectively . we also can obtain the results of control areas of soil losses in study area according to soil conservation intensity prediction model : the areas need to administrate was 317 . 77 km2 and in dire need of administration was 17 . 96 km2 in 1998
运行像元统计程序可获得该流域土壤流失结果为： 1998年试验区土壤流失总量为484 . 01万吨， 1999年则为869 . 01万吨；依防治强度预报模型可运算出研究区水土流失防治面积结果： 1998年需要治理的面积为317 . 77平方公里，急需治理的面积为17 . 96平方公里；而1999年需要和急需治理的水蚀面积上升为354 . 45平方公里和18 . 91平方公里。
