从食物消费需求角度谈中国土地利用战略

     

摘要

The purpose of this paper is to study the land use strategies in China from the viewpoint of food consumption so as to provide scientific basis for national food security and land resources sustainable use. Methods employed are documentation, induction and summarization. The results indicate that (1) With the improvement of income level, the animal consumption of urban and rural residents in China, particularly the poultry and aquatic products, has increased considerably. By contrast, the grain consumption has decreased obviously. (2) The food consumption levels and structures are significantly different between urban and rural sectors, and also among regions. (3) Grain for fodder and industrial uses have increased steadily and the ratios account to the total grain consumption have also increased in China. (4) The non-major grain production area should change the mind of being "main food consumption area" and be responsible to grain production. (5) The grain production center of gravity has changed fromthe south to the north and from the east to the middle of China. Thus the potential grain productivity should be strengthened in the south and middle of China. It is concluded with some policy recommendations for current land use strategies, such as ( 1 ) Enlarging the concept of "food" and expanding the sources of food supply to meet urban and rural residents' food demand. (2) Readjusting land use structure and paying attention to the quality protection of arable land. (3) Changing the traditional grain supply concept and improving the food supply capacity in non-major grain production area.(4) Strengthening the development of the major grain production area and enhancing its grain productivity.%研究目的:从食物消费需求角度,研究中国土地利用战略,为保障中国食物安全和加强土地资源有效管理提供科学依据。研究方法:文献分析法,归纳总结法。研究结果:随着人均收入的增加,城乡居民对粮食的消费需求呈减少趋势,而对动物性食物消费尤其是家禽和水产品消费将会显著增加。中国城乡居民食物消费结构及水平地域差异明显。中国饲料用粮和工业用粮持续增长,占粮食总消费量的比重不断提高。粮食非主产区应转变“主销区”的观念,承担相应的粮食生产任务。中国粮食生产的重心已由南方向北方、东部向中部推移,应该加强对北方及中部新增长中心的潜
