| 摘 要： | 通过对泥河沟流域刺槐林地土壤水分2 a的监测资料分析发现,在干旱年份, 土壤含水量在114.3133.2 g·kg-1范围内，平均为124.6 g·kg-1,相当于田间持水量的50%以上,大大高于凋萎湿度，土壤水分条件基本可以满足林木的正常生长。因此,对于小流域的综合治理,刺槐是较为理想的树种；而且秋季土壤水分（129.0 g·kg-1）高于春季(122.8 g·kg-1)，更利于造林成活率的提高。

| Abstract: | Based on the analysis of soil moisture of black locust forest in Nihegou watershed in two years, we discovered the soil moisture was in the range of 114.3133.2 g·kg-1, and the average value was 124.6 g·kg-, which was equivalent to 50% field moisture capacity ,so the soil moisture was satisfied for the normal growth of the forest in drought year. Therefore, black locust is the better choice for the small watershed comprehensive control; the soil moisture in autumn(129.0 g·kg-1) is higher than in spring(122.8 g·kg-1), so in autumn is favorable for the hight survival rate of afforestation. |
