Abstract


20th century, the issues of climate change and the ensuing cuts by the national experts concerned, energy saving and emission reduction have become important means of adjusting the economic structure and the transformation of development mode. Low carbon agriculture as an important part of the low carbon economy, more and more countries in the world focus their research on it.China as a large agriculture country feed one-fourth of the world population, develop low-carbon agriculture is imperative. Based on the data of input to agriculture in China’s Gansu province from1994to2010,calculaled the carbon footprint of agriculture and studied its influence factors. The purpose is that in the international and domestic situation of energy saving emission reduction, Gausu province how to reduce the resource consumption of agricultural production and the carbon footprint of agriculture, so as to improve the quality of agricultural development.This paper firstly put forward agricultural carbon footprint on the basis of the research in the current low carbon agriculture and carbon footprint. And according to the actual situation of Gansu province, selecting chemical fertilizers, pesticides, irrigation area, plastic film, diesel as the basis index to calculate the agricultural carbon footprint. Then select population scale, the agricultural economy development level and carbon efficiency, agricultural mechanization level, the level of urbanization indicators, using STIRPAT model to analyze the impact factors of Gansu agricultural carbon footprint, get the following conclusion:First, the agricultural carbon footprint in Gansu increased year by year, the carbon cost in most of the year show varying degrees of growth, although in some year reduced, but the lower is far less than the other carbon cost growth, having little impact to the total carbon footprint, so caused continuous growth of the agricultural carbon footprint of Gansu province. Second, among the Gansu province agricultural carbon costs, the pesticide use carbon cost growth most quickly, plastic film is the second, and irrigation carbon cost growth is the slowest. In Gansu province carbon footprint constituters. irrigation cause carbon cost accounts always in the first place, followed by chemical fertilizer, since1996, plastic film exceeded diesel to the third. Third.from1997to2002for the demarcation point, carbon efficiency change in Gansu province is divided into three phases: carbon-efficient reduction stages in stage, but slowing decline; the second phase, improve the carbon efficiency of stage the third stage, after a period of increasing carbon intensity, and there have been declining, but the decline rate fluctuating. Forth, among the influence factors in the Gansu agricultural carbon footprint, population, Animal husbandry fishery output per capita, agricultural mechanization level, urbanization and agricultural carbon footprint into positive relationship, carbon efficiency and agricultural carbon footprint into reverse relationship. Fifth, put forward the countermeasures to reduce the carbon footprint of Gansu province. Vigorously promote, develop low carbon agriculture development consciousness. Both, intensify government support; Strict enforcement of national laws, standards, specification quantity of agricultural input and engagement; To strengthen scientific and technological innovation, development agriculture with low carbon, ecological and high value, improving carbon efficiency.
