description	The invention discloses a southwest mountainous area reservoir chlorophyll a concentration inversion method based on GF-1 data, and the method comprises the following steps: S1, obtaining GF-1 remote sensing image data, and carrying out the preprocessing; s2, acquiring original actually measured chlorophyll a concentration data and preprocessing; s3, constructing a chlorophyll a concentration remote sensing inversion model by taking the data preprocessed in the step 1 as an independent variable and taking the data preprocessed in the step 2 as a dependent variable; and S4, verifying the model in the step 3 and carrying out error analysis. According to the method, the GF-1 remote sensing image is adopted, high-spatial-resolution, multispectral, large-area and real-time surface monitoring can be realized, comprehensive model accuracy verification is carried out on multiple common single-band and multiband combination forms based on a stepwise regression analysis method, the optimal band combination is found out
