针对水电站边坡植被混凝土生态防护工程基材土壤主要肥力因子的逐年变化问题,采集了四处植被混凝土生态防护边坡的基材土壤样品,对植被混凝土相邻年份(2008年和2009年)土壤主要肥力因子进行定量测定分析。同时,采用标准综合级别法对该四处的肥力水平进行了理化性质方面的综合性评价。结果表明:除样地2外,在一个年循环周期内,其他样地的植被混凝土基材土壤肥力因子各指标值均呈增强趋势,且各样地相邻年份肥力水平表现为隔年增加。这为植被混凝土肥力可持续演替以及植被长期稳定的生长提供了一个良好的营养水平。
According to the year-by-year changes of the main fertility factors of the substrate soil in the vegetation protection project of the concrete slope of hydropower station, four soil samples of the substrate slope of ecological protection vegetation were collected. The soil samples of the adjacent vegetation (2008 and 2009) Fertility factors for quantitative analysis. At the same time, the comprehensive level of physical and chemical properties of the four levels of fertility levels were evaluated by the standard integrated level method. The results showed that except for sample 2, the index values of soil fertility factors of all samples showed an increasing trend in one year cycle, and the fertility level of adjacent years in each sample showed an increase every other year. This provides a good nutrition level for the sustainable succession of vegetation and fertility and the long-term and stable growth of vegetation.
