煤矸石山不同坡面土壤营养元素与植被配置模式研究

The Research about Nutrient Element and Plant Configuration Mode on Different Slopes in Coal Gangue Mountain

煤矸石是煤炭生产和加工过程中主要的固体废物,堆积在矿区附近形成煤矸石山。由于煤矸石山体不同坡面上水分、温度等环境因子和土壤营养元素含量不同,导致不同坡面适宜的植物配置模式也不同。选取山西省阳泉市280煤矸石山阳坡、半阳坡、阴坡、半阴坡和平台共5种坡面,研究其土壤中营养元素的差异,并进行植被调查,分析在不同坡面上适宜采用的植物配置模式,为矿区的修复奠定基础。研究结果表明,阳坡与半阳坡上适宜种植乔灌草相结合的配置模式,阴坡与半阴坡上适宜种植以草本为主的配置模式,而平台上适宜种植以灌木和草本相结合的配置模式。

As the main solid waste of coal production and processing,coal gangue formed coal gangue mountain near the mining area.The differences in environmental factors of the moisture content,temperature and nutrient element content on slope surfaces of gangue mountains lead to different plant configuration mode suitable to different plant configuration mode.In the study,5 kinds of slope surface of sunny,semi-sunny,shady,semi-shady slopes and platforms on 280 gangue mountains were chosen in Yangquan Shanxi,research about the nutrient elements difference under various soil conditions and the vegetation diversity were investigated,and the appropriate configuration model for various slope approached.The results showed that： sunny and semi-sunny slope was suitable for planting a combination of the arbor,the shrub and grasses;shady and semi-shady slope suitable for the glasses,and the platform a combination of shrubs and herbs.
