| 摘 要： | 通过2004年2～12月对古尔班通古特沙漠南缘2年生人工梭梭和沙拐枣混交林内3条典型坡面土壤水分进行了系统监测与研究。结果表明:人工林土壤水分状况受季节性降水、人工林种植密度、地形因子的影响而出现明显的时空分异。在空间上将土壤水分变化划分为三层,0～30cm为活跃层,30～60 cm为次活跃层,60～120 cm为相对稳定层。通过主成分分析,得出地形因子、种植密度对0～30 cm土层土壤水分的影响次序为坡度>坡向>种植密度>高程,30～60 cm土层为坡向>种植密度>坡度>高程,60～120 cm土层为种植密度>高程>坡度>坡向。 |
| 关 键 词： | 人工林 土壤水分 种植密度与地形因子 古尔班通古特沙漠 |

| Abstract: | Soil moisture is one of the most important limitative factors for maintaining growth and development of mixed plantation in the Gurbantonggute Desert,and at the same time,the planting density and terrain factors have the obvious influence that can't be ignored on the variation and redistribution of soil moisture.Choosing three typical slopes in Haloxylon Ammodendron and Calligonum mixed plantation of two years'old in the southern part of the Gurbantonggute Desert as study objects from February to December,2... |
