This paper provides an in-depth analysis and research on low carbon financial support strategies from the perspective of ecological environmental protection. The understanding and analysis of the development status of ecological environmental protection inspectors, the analysis of the current rule of law construction, organizational structure, operation mechanism and capacity of the current ecological environmental protection inspectors, the understanding of the defects and problems in the work of the inspectors, to provide a basis for improving the inspection function. Through financial instruments It is of great theoretical value and practical significance to realise the full utilization of resources, the optimization of industrial structure and the low-carbon cycle development of agricultural economy. Combining the current situation and constraints of financial support for low-carbon agriculture, we propose targeted financial policy recommendations such as credit innovation for agricultural green projects rich in characteristics and conducive to the development of low-carbon agriculture, broadening private financing channels for low-carbon agriculture, and exploring low-carbon agricultural insurance. The entropy value method is used to determine the index weights, and the comprehensive evaluation method is used to calculate the comprehensive development evaluation value of the two subsystems; finally, the coupling coordination degree model is used to analyse the coupling degree and coupling coordination degree of the carbon finance and low-carbon agriculture composite systems, and the factors affecting the coupling coordination degree are analysed on this basis. Although the coupling level between them is at a low level of coupling, it is in transition to a medium coupling; the coupling coordination degree is at a mild disorder, and gradually in transition to a near disorder.
