  3. By surveying the sample plot, the relations between the stabil ity of the mountai n slope of soil preparation for planting by using explosion and other factors s uch as precipitation, terrain ， were studied. by using the method of quantitative t heory i, the interrelation between the damaged degrees of soil preparation progra ms by using explosion in low mountain area with abundant precipitation and terrain factors was systematically analysed, and the mathematical models relate d were developed. the results show that the precipitation in early days and the m aximum precipitation per day are the primary factors causing the soil prepara tion program damaged. the main terrain factors of the mountain slope that affect the program stability are according to their importance, slope, position and dir ection. the suitable mountain slope for soil preparation by using explosion is th e slope of less than 25

    通過典型標準樣地調查資料，探討了造林爆破整地工程的坡地穩定性與降水、地形等因子的相互關系，應用數量化理論，對在有充分降水條件下的低山丘陵區的爆破整地工程損失程度與地形因子之間的關系進行了系統分析，並建立了相應的數學模型，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損失的激發因素；影響爆破整地工程穩定性的主要地形因子是地面坡度，其次為坡位、坡向，實施爆破整地工程的地面坡度以不超過25為宜。
