| 摘 要： | 系统地研究延安研究区的天然植被土壤水分对于认识植被建设的环境具有重要意义,研究结果表明水分条件可以保证植被的正向演替和群落的稳定,虽然在天然植被中也存在土壤低含水层(土壤干层) ,但这是一种正常的自然现象,而且,对植被的自然更新、演替和形成稳定群落没有根本性的影响。文中给出了延安研究区主要植物群落类型土壤水分的适宜范围 |
| 关 键 词： | 植被演替 土壤水分 土壤低含水层 植被建设 |

| Abstract: | The systematical study on soil moisture of natural vegetation in Yan'an experimental area have major significant to recognized environment of vegetation reconstruction, the study results showed as follows. Soil moisture condition of Loess Plateau could ensure the positive succession of vegetation although there is a layer of lower soil moisture in natural vegetation that is a normal natural phenomenon. Furthermore, the layer of lower soil moisture has not fundamentally effect on the natural renewal, succession and forming a stable community of vegetation. The ranges of soil moisture of main plant community types in Yan'an experimental area are listed in the paper. |
| Keywords: | vegetation succession soil moisture layer of lower soil moisture vegetation construction |
