Abstract: Based on the leaf and root economic spectrum, we analyzed the plant economic spectrum, and further analyzed the correlation between underground and aboveground about plant economic spectrum, in the meantime, we evaluated its correlation research. Based on the existing research results, we elaborated the plant economic spectrum though the functional traits covariation consist of leaf lifespan, specific leaf area, photosynthetic rate, respiration rate, nitrogen and phosphorus concentration. And we researched the functional traits covariation consist of the root diameter, root dry matter content, specific root length, carbon and nitrogen content, water soluble compounds, cellulose and lignin concentration, in order to explain the root economic spectrum in detail. Meanwhile, by the summary of the functional traits covariation, the correlation of the plant economic spectrum between the underground and aboveground was worked out. In order to further understand the plant economic spectrum, the following contents were put forward: increase the species and community of the plant economic spectrum, analyze and integrate the functional traits parameters of the whole plant, establish global plant economic spectrum model, explore the impact of environmental factors on plant economic spectrum. Through the plant economy spectrum was detailedly analyzed and discussed , which can provide technical support for this new research direction.
