众所周知,对于已开垦过的丘陵坡地来说梯田是控制土壤侵蚀的最有效的物理方法之一.在印度东北部丘陵地区农业经济和社会经济占优势的条件下,为了求出建造梯田的垂直间隔和台阶的宽度,已经取得了成果即建立一个简单的数学关系式.为了人类生存.在由农业和社会经济结构组成的丘陵地区开垦坡地是迫切的.方程中挑选出的参数是土壤的坡度和土壤下垫面的最小平均深度,这是以前没有考虑过的,是陡坡最大的限制因素.倾斜角度构成了方程的第三个参数.在不同的坡度和土壤深度组合下,根据方程可以求得不同组合条件下的垂直间隔和台阶的宽度,并且用几何图形表示出来.
It is well-known that terraced fields are one of the most effective physical methods for controlling soil erosion in the reclaimed hilly slopes.Under the agro-economic and socio-economic dominance of hilly areas in northeastern India, in order to find the vertical spacing of terraced fields And the width of the steps have already achieved the result of establishing a simple mathematical relation.For humankind’s survival, it is urgent to reclaim the sloping fields in the hilly region consisting of agriculture and socio-economic structure.The parameters selected in the equation are the slope and The lowest average depth of the soil underlying surface, which was previously not considered, is the largest limiting factor for steep slopes, which form the third parameter of the equation, which can be obtained from the equations using different slope and soil depth combinations The vertical spacing and the width of the steps for different combinations are shown graphically.
