中国米质气候资源的地域分布

稻米品质受着气候条件的明显影响。在我国不同地域，米质气候资源各不相同，对米质的影响也各具特色，总的趋势是，北方优于南方；西部优于东部；晚茬口水稻优于旱茬口；在地形复杂地区，米质气候资源还具有垂直地带性结构。我国丰富的米质气候资源为各种类型优质米的生产创造出优越的环境条件。

REGIONAL DISTRIBUTION OF CLIMATIC RESOURCES IN RELATION TO THE RICE-QUALITY IN CHINA

The rice quality is affected obviously by climatic conditions. The rice-quality climatic resources are diversified in various regions of our country and their influences upon the rice quality have their respective characteristics. The general trend of the distribution of such climatic resources is that the resources in the north are more excellent than those in the south,the resources in the west are more excellent than those in the east, the resources of the latestubble rice are more excellent than those of the early-stugbble rice,and the resources in the regions with complex terrain have vertical zonality structure. The rich rice-quality climatic resources create superior environment for the production of the good quality rice of various types in our country.
