The environmental differences between an alpine and a lowland environment near the sites sampled in this study, based on [34].

Only soil NH3 is provided, as other soil nutrients (NO3 and PO4) follow a similar pattern (higher nutrient and organic content in alpine than lowland). PAR - photosynthetically active radiation.

本数据集仅提供土壤氨（NH3）相关数据，其余土壤养分（硝酸盐NO3与磷酸盐PO4）均呈现相似的变化规律——高寒地区的养分与有机质含量均高于低地地区。其中，PAR指代光合有效辐射（photosynthetically active radiation）。
