Abstract: According to the latest FAO statistics, analysis was made of the international walnut harvest area and production quantity. The results showed that Asian, North America, Europe and South America were main walnut cultivation areas, where the harvest area and production quantity occupied respectively 98.07% and 98.86% of the world. Although walnut industry made great progress in China, varietal mixture, the low degree of improved variety, unreasonable cultivation and management seriously restricted the development of walnut industry. Therefore, some countermeasures should be adopted, such as raising the degree of improved variety, adopting reasonable cultivation and management, to insure healthy developmen of Chinese walnut industry.
