| 摘 要： | 以清江流域的两个工程为例,对岩石边坡和混凝土边坡的植被混凝土的肥力差异性进行了试验研究;分析了植被混凝土的各项理化指标:这两种边坡的植被混凝土容重和酸碱度差异不大,但混凝土边坡的植被混凝土含水率远低于岩石边坡;而作为表征植被生长指标的速效磷、碱解氮则是混凝土边坡远高于岩石边坡.以上述试验分析结果为基础,最终明确了影响植被生长的关键因素.

| Abstract: | Under the background of two engineering examples in Qingjiang River,we studied the fertility difference of vegetation-growing concrete between rock and concrete slope.Through analyzing various physical and chemical indicators of vegetation-growing concrete,we firstly found that the bulk density and pH value,as the inherent properties of soil,make no significant difference between concrete and rock slope; while the moisture content of rock slope is significantly higher than that of concrete slope.Secondly,we found that the available phosphorus and nitrogen of it were significantly lower than that of concrete slope.Based on above experimental results,finally we make sure the key factor of deeply affecting the vegetation growth of slope. |
