| 摘 要： | 通过对黄土高原沟壑区南缘的油松(Pinus tabulaeformis)、刺槐(Robinia psedudoacacia)人工林及荒坡的土壤水分有效性和亏缺状况的分析发现,无论是土壤水分有效性,还是水分状况都表现出油松＞刺槐＞荒坡的特征,据此认为,在该区造林工作中,如果立地条件允许,更适宜造油松林;不但降水的多少影响着土壤的干湿状况和土壤水分的有效性,降水的分布状况尤其是生长季中的降水分布状况也严重影响土壤水分干湿状况和有效性.

| Abstract: | The soil moisture availability and deficit state of Pinus taulaeformis plantation, Robinia pseudoacacia plantation and uncultivated lands in Chunhua county, Shaanxi province were studied from April 1999 to March 2000. The results showed that both the availability of soil water and the soil water state were P. tabulaeformis>R. pseudoacacia forest>uncultivated land. It is thought that P. tabulaeformis should be planted if the site condition fitted. The moisture content and deficit were affected by precipitation and the distribution of rainfall, especially that during growing season. |
