| 摘 要： | 文章采取典型样地调查的方法,对不同带间距对柠条林的影响进行研究,结果如下:①柠条灌丛生长中冠幅、树高、新梢的相关性较强,各带间距林地柠条3个生长指标排序均为:2m>16m>8m>4m;丛径排序均为:2m>4m>8m>16m;枝条数量排序均为:4m>8m>2m>16m。②2m、4m、8m、16m带间距林地一年生枝叶与多年生枝的比例依次为3∶7、1∶9、3.4∶6.4、4∶6,8m和16m带间距林地柠条的饲用价值更为突出。③4m、8m带间距林地土壤含水量接近,且垂直分布较均匀,好于2m、16m带间距林地。④随带间距增加风速和湿度增加,温度下降;2m带间距林地作用较明显,其他3种林地则作用相似。⑤4m、8m带间距林地优质牧草重要值占总值的51.79%~43.03%之间,多年生植物重要值占总值的1/3左右,好于2m、16m带间距林地。⑥柠条林带间植物多样性指数排序为:16m>4m>8m>2m,丰富度指数排序为:2m>8m>4m>16m,均匀度指数排序为:2m>8m>4m>16m。⑦综合柠条生长情况、带间植物重要值和多样性指标、林地土壤水分和林地对小气候的调控作用,4m、8m带间距林地在研究地是比较适合的造林模式。

| Abstract: | Typical plot investigation method was used in this paper to study on the effect of different spacing between strips on Caragana plantation.Results are as follows:1)There is strong relative relationship among the crown width,height,shoot of Caragana shrub.The order of those above growth indicators are: 2m> 16m> 8m> 4m;the order of tuft size are: 2m> 4m> 8m> 16m;the number of branches are: 4m> 8m> 2m> 16m.2)The ratios of annual and perennial branching with a spacing of 2m,4m,8m,16m are 3:7,1:9,3.4:6.4,4:6.The... |
