- 摘要:
- 以黄龙滩生态护坡工程为对象,通过现场取样和室内处理测定,研究了水泥边坡植被混凝土肥力指标随坡向、坡位和年限的变化特性.结果表明：不论阴坡或阳坡,3个坡面地形部位(上坡位、中坡位、下坡位),下坡位物理结构最好,营养水平也较高,其中有机质、速效磷、速效氮含量受坡位影响极显著(P<0.01).阴坡各项指标(除容重外)均优于阳坡,其中含水率、pH值差异极显著(P<0.01).年限则对全磷和速效钾含量影响极显著(P<0.01).相关分析表明,基物理指标与营养因子间存在相关关系,说明土壤结构与养分积累存在相互影响.
- Abstract:
- The effects of slope positions and directions and years on fertility properties of ecological protected-slopes in Huanglongtan hydropower station was studied through field sampling and indoor determination.The results showed that among three positions(upper slope,middle slope,lower slope),the lower slope had the best physical composition and higher nutrition level,while the effects of directions on the content of oganic matter and available phosphorus and available nitrogen were very significant(P<0.01).Other than bulk density,the indicators of shady slope were better than sunny slope,while soil water content and pH had very notable difference(P<0.01).The effects of years on the content of soil total phosphorus and available kalium were very conspicuous(P<0.01).The correlation analysis showed that there were correlalative relations between substrate physical indicators and nutrient factors,which indicated that soil composition and nutrient accumulation interacted each other.
