摘要：The content of nitrogen, phosphorus, potassium and organic matter in soil is an important index to determine soil nutrient status. In this paper, the contents of nitrogen, phosphorus, potassium, organic matter and soil salt in the soil of several different plant communities in the campus were measured by the chemical measurement characteristics of several different communities in University of Jinan. The differences in the measurement characteristics of soil chemical measurement in different plant communities were analyzed. The results showed that the highest organic matter content in several communities was Cherry Blossom community, 76.33mg/kg, and the highest ammonium nitrogen content was 196.08mg/kg; the highest content of available phosphorus was the community of Begonia, 168.14mg/kg, and the highest content of available potassium was the community of Robinia pseudoacacia, which was the highest salt content in 64.99mg/kg soil. The community of cherry blossoms is 569 μs. There was little difference in soil organic matter, available phosphorus and available potassium in different plant communities..
