Granite red quality is light, Sha Xingchong, and knot holds power difference, and easily by rain-out, the ridge, innovation become short, reduce; Due to natural subsidence, comparatively large on the contour impact of the low bank of earth between fields, particularly become the 1st year of the ridge (innovation), herbage covers limited, it is very general that the low bank of earth between fields (innovation) damages phenomenon, according to observation, see table 8, under the ridge (innovation) condition do not rebuild by the large nest of band innovation wholely, 1st year the ridge (innovation) become short 2.1cm, reduce 3.2cm, and the low bank of earth between fields does not wait the low bank of earth between fields up to 100%, 22.5% to be washed out; 2nd year the ridge (innovation) become short 2.7cm, reduce 3.7cm, and the low bank of earth between fields of 31.4% is washed out.
The low bank of earth between fields (innovation) the damaged condition table of comparisons under table 8 not trimming condition
Band innovation large nest is wholely owing to being with native innovation, and long-pending rain face diameter stream all can collect at large nest Inner, and institute be with silt to become in large nest Inner sedimentation the soil that becomes silted up, and these silts are native can have a strong impact on the water holding volume of large nest if do not removed, unfavorable to conserving water and soil.According to observation, see table 9, under herbage condition is not planted in long-pending rain face, the thick 11.2cm of annual mud, like this, only need 3 years, large nest just can become silted up full, forms new hillside fields, produces new water and soil loss, therefore, within behind whole ground the 3rd year, increases 899.9m3/hm than the 1st annual flow behind whole ground
2, increase by 114.3%, increase at double; Under the kind herbage condition of long-pending rain face, annual mud is thick also reaches 8.5cm, within behind whole ground the 3rd year, increases 467.2m3/hm than the mat woven of fine bamboo strips 1 annual runoff behind whole ground
2, increase by 113.3%, also increase at double.This illustrates, whether no matter long-pending rain face plant grass, as long as not desilting, the ability that large nest stores rainwater will obviously reduce.
The rainy long-pending face of table 9 not desilting condition is not planted grass and plants the careless water and soil loss table of comparisons
