Abstract
The relationship between crop fertilization and non-point source (NPS) pollution is a hot topic of research on agricultural NPS pollution. In this paper, the upper reaches of Erhai Lake Basin were taken as the research area. Based on rice-broad bean and maize-potato rotation, the content of chemical oxygen demand (COD), total phosphorus (TP), ammonia nitrogen (AN), nitrate nitrogen (NO3-N), and total nitrogen (TN) in water samples from experiment field plots under normal fertilization, 60% normal fertilization and 30% normal fertilization were measured, and the response relationship between fertilization levels and the values of the indicators was explored by using the method of split-plot experiments and statistical analysis. The experiment results are as follows: (1) The fertilization level of different crops had a significant (P < 0.01) effect on agricultural NPS pollution, and the effect on TP was the strongest (R2 = 0.550; P < 0.01). COD has the second highest impact. (3)The content of AN and NO3-N measured from field plots of maize and broad bean had no significant relationship with the fertilization level, but the content of nitrogen measured from plots of potato presented a downward trend with the increased amount of fertilizer. (4) Overall, the amount of fertilizer positively affected agricultural NPS pollution, and there was a correlation between the indicators. This study can provides new ideas for the evaluation and delineation of the spatial pattern of source-sink risk of NPS pollution in the basin, and puts forth new methods for the management of NPS pollution in the basins of low-latitude plateau fractured lakes similar to the Erhai Lake Basin.

Highlights
1. The main crop rotations are established to be rice-fava bean and maize-potato rotations through field research in the study area.
2. The relationship between fertilizer application levels of different crops and agricultural NPS pollution in the studied basin is modelled.
3. TP, COD, NO3-N, AN and TN are the main indicators for NPS pollution in the study area.
4. NF, 60%NF and 30%NF fertilization can effectively reveal the relationship between the fertilization level and NPS pollution.
5. The fertilization level of different crops had the most significant effect on the content of TP (R2 = 0.550, P < 0.01). The research can provide new ideas and methods for ecological environment management of Erhai Lake Basin.
