The Study On The Grain Production And Countermeasures In The Cropping-Grazing Ecotone Rural Areas In Inner Mongolia Under The Background Of Climate Change

In the background of global climate change, due to the increase of population, the reduce of arable land, and environmental degradation together with the energy crisis, grain production has been a serious threat, which arouses the concern of the world’s governments and international organizations. In this century, bad weather and climate condition appear frequently in cropping-grazing ecotone of Inner Mongolia, and also greatly exacerbate the contradictions of grain production. Therefore, in the background of climate change, study the grain production in cropping-grazing ecotone of Inner Mongolia can help promote advances in agriculture, increase people’income, improve the ecological environment, and achieve the sustainable development of agriculture.Based on the climate data of47countries in cropping-grazing ecotone of Inner Mongolia, the article analyzes the change of climate in farming-pastoral zone of Inner Mongolia and its development trend. And the study shows that temperature shows a clear upward trend Inner Mongolia cropping-grazing ecotone, and the annual average wind speed shows a decreasing trend, while the annual precipitation of each year shows a large fluctuation, basically showing the trend of a slight increase.Based on the study of climate changes, through the research of grain production data and climate data of35sample countries from2001to2004in Inner Mongolia cropping-grazing ecotone, there is a comprehensive analysis of the impact that climate factors and agricultural inputs do on the grain production. And the article focuses on the impact of climate change. First, it shows a simple correlation between the climate factors, agricultural inputs and grain production. Then, through econometric methods, it establishes a multiple regression to analyze the empirical relationship between temperature, precipitation, irrigation, fertilizer and grain production. Finally, according to the analysis above, the paper proposes policy recommendations, aimed at promoting sustainable agricultural development in Inner Mongolia cropping-grazing ecotone, and providing a scientific basis for government departments to make decisions.
