世界马铃薯生产发展基本态势及特点

马铃薯是世界第四大粮食作物，在世界范围内有着广泛的种植，关注世界马铃薯生产的发展情况对发展中国马铃薯产业有着重要的指导意义。从世界马铃薯生产角度出发，分析了世界及各区域马铃薯生产的状况和历史变迁，对世界马铃薯生产状况做出基本判断。研究结果表明：（1）世界马铃薯生产集中在“三区两带”，即高山地区、低地热带区、温带区三大主产区，23°—34°N、44°—58°N两个纬度带，占世界种植面积70%以上；（2）马铃薯在世界有着广泛的种植，但生产水平和农业生产地位差异较大；（3）世界马铃薯生产重心正在由西向东、由发达国家向发展中国家转移；（4）世界马铃薯生产格局正在发生重大变化。

Analysis on the Basic Trend and Characteristics of World Potatoes Production

Potatoes is the world's fourth largest food crop, widely planted in the world, about 160 countries growing potatoes. Concerned about the development of world potato production is favorable to China's potato industry. This paper analyzed the world and regional potatoes production and its historical evolution from perspective of world potatoes production, and made some basic judgments. The results showed that: world potatoes was intensively distributed in three zones, which were the high mountain zone, lowland tropical zone, and temperate zone. There were two remarkable latitude bands, which were 23° N-34° N and 44° N-58° N, accounting for 70% of total potato area. Potatoes was widely cultivated in the world, but production differs from country to country. World potatoes main producing area is transferring from the developed countries to the developing countries. World potato production pattern is undergoing huge changes.
