摘要: 1980年作者与卢其尧曾在本刊发表了“中国农业气候区划试论”一文。近两年来,中央气象局与有关单位协作,提出了“全国农业气候区划初步方案”,出版了《我国农业气候资源与种植制度区划》,中国农业科学院先后完成了小麦、甘蔗、甜菜、柑桔、茶树、烟草等作物的气候区划,各省、市、自治区也陆续进行了各自的农业气候区划。

Abstract: A former paper (Acta Geographica Sinica, Vol. 35, no. 2) by the present author and Lu, using hydrothermal condition, presented a tentative regionalization of agroclimate of China, three large regions were defined, the monsoon area, the arid area and the Tibetan Plateau. Regions of order 2 were based on the accumulated temperature above 10℃ and as for the regions of order 3, the aridity was adopted as the main index.In this paper, some principles for regionalization are revised as follows:1. In the former paper, the warm temperate climate belt was divided into two partsbut they were combined into one in the present paper. As for the Tibetan Plateau, three belts are defined: highland cold, sub-cold and temperate climate.2. Regions of order 3 not only defined according to humidity conditions, but also the differences in temperature and other factors as landform, surface water, soil and vege-tation are considered combinatively.3. Some climatic indexes used as bases in former case are modified and the bounda-ries have been redrawn. For example, the boun dary that separate the regions of aridity from the monsoon area is moved eastward to the west side of Daxingan Ling Mt., which is the crisscross area of pasture land and farm land. Belts define above may further reflect the differences between agriculture and pasture and so the cropping system; the regions of order 3 fit well to the physical environment, as well as in guiding agricultural development.
