From the perspective of meteorology, the present invention makes full use of the characteristics of easy availability, good consistency and predictability of meteorological or climate data, to carry out the prediction and evaluation of the regional eco-quality annual harvest. Further, the present invention has the advantages of simple operation, easy promotion and application, and high indication significance.Drawings of the Description Obtain the climate production potential of a region to be evaluated 3101 Calculate the pro and con yields K of the region to be evaluated according to the climate production potential of the region to be evaluated, wherein the pro and con yields K of the region to be evaluated refers to the increase and decrease S102 percentages of the climate production potential of the region to be evaluated relative to standard climate average status production potential Determine the regional eco-environment quality grade corresponding to the pro and con yields K of the region to be evaluated according to the preset correspondence relationship between the pro and con yields K and the regional S103 eco-environment quality grade Output the pro and con eco-quality annual harvests corresponding to the regional eco-environmental quality grade according to the preset correspondence S104 relationship between the regional eco-environment quality grade and the pro and con eco-quality annual harvests FIG. 1
