Some modifying suggestions on the "Further Study on the Eegionalization of Ag-roclimate of China" (Acta Geographica Sinica, Vol. 38, No. 2) are delivered as follows: (1) The grades are simplified. Sub-belts are replaced by belts, and 46 regions are deduced to 39. (2) indices and boundaries for the regionalization are defined more definitely. (3) Boundaries of regions are defined mainly by precipitation and its distribution, and make them coincide with the natural regions.
