- W2378342357 abstract "As a huge agricultural country, food security is very important for the stability of society and sustainable development of social economy in China for all the time. There are many ways to increase the food security level, among which crop trade is a major way, especially under the globalization background. Crop trade may cause the input or output of many resource and ecological factors, which may generate some effects of resource, ecology and economy. Among these factors, Virtual water flow embedded in crop trade has been studied in many papers, but other factors were ignored in some degree, and there are still few achievements in this field till now. As for the effects of resource, ecology and economy, there are fewer studies. In this paper, flows of virtual resource factors (virtual water, virtual land) and virtual ecological factors (virtual chemical fertilizers, virtual pesticides, virtual agricultural film) caused by the crop trade in 2000 and 2008 in China were calculated from both the international and interregional aspects. The results indicate that the flows of both two factors show an expanding tendency in both international and interregional aspects. In international aspect, there is an obvious expansion of net imports of virtual resource and ecological factors, and the main reason is the rapid increase in soybean imports. In interregional aspect, South China and Southwest China are the most important inflow regions of virtual resource and ecological factors while Northeast China, North China and the middle and lower reaches of Changjiang River are the main discharge regions. In addition, the paper has respectively discussed the effects of resource, ecology and economy caused by the flow of virtual resource and ecological factors embedded in grain trade. The results show that the discharge regions ’agricultural resources and agricultural ecological environment have to endure great pressure, and the terrestrial natural ecosystems are being threatened due to diversion of green water by agricultural production. Moreover, the economic development also suffers great losses. At the end of the paper, policy enlightenments for the support mechanism of virtual resource and ecological factors’flow in China were put forward from such five aspects as refining the agro-ecological compensation mechanism, implementing the water resources assistance strategy, carrying out the water transfer projects across river basins, developing water-saving and green agriculture and extensively utilizing the international resources." @default.
