An Empirical Study on agricultural productivity and pollination

为了考虑传粉媒介的重要性，本研究的重点是农业与蜂业之间的关系。为了了解养蜂业的经济状况，对油菜籽生产进行了评价，作为一种花蜜供应。对黄芪、豇豆种植减少的进一步分析表明，水稻生产与养蜂之间的经济关系发生了变化。通过分析作物之间的竞争或互补关系，可以从生态环境的角度重新认识农业生产力的概念。

This study focuses on the relation between agriculture and apiculture in order to consider the importance of pollinators. To know the economic situation of apiculture, the rapeseed production is evaluated as a nectar supply. The further analysis of the decreasing of planting astragalus, milk vetch, shows that the economic relation between rice production and apiculture has changed. Through analyzing some competitive or complement relations between crops, the concept of agricultural productivity could be reconsidered from the ecological and environmentalperspective.
