| 利用区位商的概念研究了17种农作物大类的空间分布和各地农业种植结构的演化，从自然因素和经济因素两方面解析了中国农业种植结构分布和变化的原因和动力。得出的主要结论为中国农业种植结构的空间分布主要是由自然条件决定的，而其分布的变化则主要是经济行为的结果；劳动力密集型的种植比重同人均土地资源的数量呈负相关，土地密集型的种植比重同人均土地资源的数量呈正相关；城镇化和人口发展决定了蔬菜生产的分布和变化，城镇化还影响着各地的复种指数的变化。提出政府应加强对各种农产品市场的状况分析和信息服务等对策。 |

| Abstract: |
| This paper utilizes the concept of location quotien to study the space distribution of 17 crops and the changes of agriculture planting structure in various locations. It resolves the reasons and motivations for the distribution and changes of agriculture planting structure in China from natural factors and economic factors. The conclusions are that the space distribution of agriculture planting structure in China is mainly determined by the natural conditions, while its changes in distribution are mainly resulted from eco nomic behavior. The planting specific gravity with intensive labor shows negative relation with the amount of land resources per capita. The planting specific gravity with intensive land resources shows positive relation with the amount of land resources per capita. The urbanization and population development determines the distribution and changes of vegetable production. The urbanization also influences the changes of multiple cropping indexes of various places. This paper puts forward several counter measures that the government should strengthen its analysis on markets of various agriculture products and provide more information services. |
