摘要:

为探究植物措施对沙漠光伏电站土壤理化性质的影响,以电站内羊草、甘草、油蒿、花棒及沙障样地为研究对象,测定各样地土壤粒度、容重、孔隙度及养分指标。结果表明,研究区土壤细沙、中沙、极细沙3种主要粒级含量达90%以上,其中羊草措施<0.25 mm组分含量最高。0 —30 cm土层土壤容重为1.47~1.67 g·cm-3,毛管孔隙度为14.53%~31.52%,均以沙障措施的土壤结构性最优。0 —30 cm土层羊草措施碱解氮、速效钾含量最高,甘草措施有机质含量最高,花棒措施速效磷含量最高。研究可为沙漠光伏电站生态保护修复提供理论依据。

Abstract:

In order to explore the effects of plant measures on soil physical and chemical properties of photovoltaic (PV) power station in desert, soil grain size, bulk density, porosity and nutrient indexes were determined with sample plots planted Leymus chinensisGlycyrrhiza uralensisArtemisia ordosicaHedysarum scoparium and sand barrier in the power station, respectively. The results showed that the granularity content of fine sand, medium sand and extremely fine sand in the study area was over 90%, among them, the content of components <0.25 mm in Leymus chinensis measure was the highest. The soil bulk density of 0—30 cm layer ranged from 1.47 to 1.67 g·cm-3, and the capillary porosity was 14.53%~31.52%. The soil structure of sand barrier was the best. In 0—30 cm soil layer, the contents of alkali-hydrolyzable nitrogen and available potassium in Leymus chinensis, organic matter in Glycyrrhiza uralensis Fisch and available phosphorus in Hedysarum scoparium were the highest. The research results could provide theoretical basis for ecological protection and restoration of desert PV power stations.

Key words: bulk density, porosity, nutrients, photovoltaic power station
