美国西部正在进行密集的能源开发，因为大量的煤炭储量很容易通过地表开采获得。这项研究提供了从三个州（亚利桑那州、新墨西哥州和北达科他州）地表采矿场收集的弃土和表土的物理、化学和生物特性的基线数据。通过聚类分析和多元线性回归方法，对土壤理化性质与藻类的分析数据进行整合，揭示了不同的关系。高钠和低氮水平可能是亚利桑那州和新墨西哥州站点蓝绿藻占优势的原因。其他营养物质，如钙、氯化物和某些微量元素可能对土壤藻类群落很重要。藻类在演替和土壤发生中的重要性被强调。
Intensive energy development is taking place in the western United States, because of the large coal reserves that are readily available by surface mining. This study provided baseline data on the physical, chemical and biological properties of spoil and topsoil collected from surface mined sites in three states (Arizona, New Mexico and North Dakota). Integration of analytical data on the physical-chemical properties of the soils with the algae present revealed distinct relationships by the cluster analysis and multiple linear regression methods. High sodium and low nitrogen levels may have accounted for predominance of blue-green algae at the Arizona and New Mexico sites. Other nutrients, such as calcium, chloride and certain trace elements may have been important to the soil algal community. The importance of algae in succession and soil genesis is stressed.
