摘　　要：通过对珠江源头区站马地集水区试验点造林前不同土地利用类型土壤的水分和养分的分析结果表明:各土地利用类型在垂直分布的状态下水分可分为降低型和增长型;土壤通透性能均较好,植物根系增殖不会受到抑制;耕地与林地土壤容重相差10%左右;耕地与林地土壤的有机质含量相差50%左右,N、P等其他元素的含量相差约30%左右。The soil water and nutrient of Zhanmadi watershed of headstream area of Zhujiang river were analyzed. The results showed that under the condition of vertical distribution, the soil water of different land use types could be classified into two types of either decreasing or increasing. The permeability of soil was promising, and the root growth of plant will not be restrained. There was 10 % difference between the volume weigh of soil in arable land and that of forest land. The difference on the content of organic matter and other nutrient elements such as N and P were around 50 % and 30 % respectively.
