The invention relates to a processing method of ecological agriculture comprehensive benefit evaluation. The processing method includes that: a stem line body group b of a target ecological agriculture system is b=(b1, b2,..., bn) T; benefit state vectors are built: w (e) n*1=(e1, e2,..., en) T; associated weight matrixes Rn*n of stem line bodies are built according to the incidence relation of the stem line bodies; a start vector is made to be (img file='DDA0000600858560000011. TIP' wi='384' he='72'/) (/maths), and iteration is conducted according to a formula: (img file='DDA0000600858560000012. TIP' wi='568' he='94'/) (/maths); iteration processing is finished when (img file='DDA0000600858560000013. TIP' wi='184' he='72'/) (/maths) and (img file='DDA0000600858560000014. TIP' wi='208' he='72'/) are zero; (img file='DDA0000600858560000016. TIP' wi='64' he='67'/) in the obtained (img file='DDA0000600858560000015. TIP' wi='144' he='86'/) is the comprehensive benefit gross output evaluation result of the target ecological agriculture system, and (img file='DDA0000600858560000017. TIP' wi='184' he='80'/) is the comprehensive benefit evaluation result of the target ecological agriculture system. The processing method views the comprehensive benefit evaluation process of the ecological agriculture system as an open, nonlinear function, and accordingly can obtain more accurate processing results after processing of the ecological agriculture comprehensive benefit evaluation.
