Abstract: The proposal of China's "double carbon" strategy provides a good opportunity for the realization of the value of ecological service products. Green space carbon sinks play an irreplaceable role in the realization of the carbon neutrality vision with their special carbon sequestration properties. Through the technical classification and comparison of the research results of green space carbon sink, this paper discussed the technical path and measurement monitoring method of green space carbon sink value realization based on carbon neutralization vision. Given the technical problems existing in the realization of green space carbon sink value, this paper put forward three technical suggestions: selecting the appropriate carbon sink technology evaluation system, improving the technical rules of carbon sink accounting, and paying attention to carbon sink baseline survey. The paper aimed to help realize the ecological service value of green carbon sink from the perspective of carbon neutrality.
