我国干旱半干旱地区的土壤大部分属于易侵蚀土壤。水的流失是引起土壤侵蚀的主要原因,是制约我国地区经济社会可持续发展的重要限制因子。本试验利用室内模拟人工降雨方法,研究不同降雨强度(50mm/h和100mm/h)对碱性坡耕地(坡度为5°)土壤侵蚀的影响。
我國榦旱半榦旱地區的土壤大部分屬于易侵蝕土壤。水的流失是引起土壤侵蝕的主要原因,是製約我國地區經濟社會可持續髮展的重要限製因子。本試驗利用室內模擬人工降雨方法,研究不同降雨彊度(50mm/h和100mm/h)對堿性坡耕地(坡度為5°)土壤侵蝕的影響。

In the arid of semi-arid areas in our country ,most of the soils belong to easy eroded soil . The water loss is the main cause that lead to soil erosion , and is the main limit factor that restrict the sustainable development of economic society of some regions of our country . The paper's test utilizes the laboratory test method to simulate artificial rainfall , and studies the influence of different rainfall intensities (50 mm/h or 100 mm/h) on soil erosion of alkaline sloping cultivated lands (with a gradient of 5 degresses).
