摘要
通过典型标准样地调查资料，探讨了造林爆破整地工程的坡地稳定性与降水、地形等因子的相互关系，应用数量化理论Ⅰ，对在有充分降水条件下的低山丘陵区的爆破整地工程损失程度与地形因子之间的关系进行了系统分析，并建立了相应的数学模型，研究指出，充分的前期降水和日最大降雨量是引起爆破整地工程损失的激发因素；影响爆破整地工程稳定性的主要地形因子是地面坡度，其次为坡位、坡向，实施爆破整地工程的地面坡度以不超过２５°为宜。
By surveying the sample plot ,the relations between the stability of the mountain slope of soil preparation for planting by using explosion and other factors such as precipitation,terrain, were studied.By using the method of Quantitative Theory I,the interrelation between the damaged degrees of soil preparation programs by using explosion in low mountain area with abundant precipitation and terrain factors was systematically analysed,and the mathematical models related were developed.The results show that the precipitation in early days and the maximum precipitation per day are the primary factors causing the soil preparation program damaged.The main terrain factors of the mountain slope that affect the program stability are according to their importance ,slope ,position and direction.The suitable mountain slope for soil preparation by using explosion is the slope of less than 25°.
