| 摘 要： | 坡度作为一个重要的地形因子,对地区内的植被生长有着重要的影响,不同坡度条件下的坡面植被生长状况存在很大差异。为探明坡度与植被生长状况之间的关系,采用实验室对比试验研究分析方法研究了10°、20°、30°、40°、50°五个坡度条件下各100粒植物种子的生长变化关系。结果表明:随着坡度的增大种子的流失率呈增加趋势,10°~30°坡度范围内增加幅度较大,其中20°~30°范围内增幅最大,30°~50°坡度范围内增幅较小;随着坡度的增大坡面植物的生物量明显下降,其中在10°~30°下降的最快,30°~50°下降趋势减弱。

Red Soil Vegetation Growth Status Study on Different Slopes |

| Abstract: | The slope of the terrain ,as an important factor ,has important implications in the region of vegetation growth ,different slope was different under the slope vegetation growth status .In order to investigate the slope and vegetation growth status and the relationship between laboratory ,a comparative experimental was conduc‐ted to study 100 grain seed growth relationship under five slope method of 10° ,20° ,30° ,40° and 50° .The re‐sults showed that with the increasing of the slope seed loss rate ,the 10°~30° slope range increased greatly ,and 20°~30° amplitude was maximum ,within a smaller increasing for 30°~50° slope;with the increasing of the slope surface vegetation biomass decreased significantly ,10°~ 30° dropped quickly ,30° ~ 50° had a weaker dow n trend . |
