Study On Emergy Analysis Of Anhui Agriculture Eco-economic Systems

The agricultural ecological-economic system in Anhui Province is main study object of this thesis. In this thesis, the input-output and sustainable development conditions of agrosystem in Anhui Province are assessed, and main influential factors of agricultural development are analyzed.According to the energy the cycle of operations, this article divided the Anhui Province agriculture ecology economic system's resources investment part into four bulks, respectively, which are renew the environment resources, unrenew the environment resources, unrenew the industry auxiliary, renew organic resources; the output unit divides into the crop production, the forestry, the livestock industry, the fishery four parts. Counted them to put into production the situation separately, then carried on to it emergy computation. Established 1997-2008 year Anhui agricultural system to be able the value analysis time series, and overcame the static state to be able the value analysis insufficiency. In this foundation, establish the emergy evaluating indicator system in view of the Anhui Province sentiment. Through a series of the emergy appraisal target analysis, we thought that the Anhui Province agriculture ecology economic system is at the quite preliminary stage, and the emergy investment structure is unreasonable, has organic emergy to invest the insufficiency, the ecological environment pressure is also quite big, delivers the structure also to need to make the adjustment. We should enlarge the bigger emergy transfer ratio product output, to increases the economic efficiency. The Anhui Province related government should note this situation as soon as possible, and develop ecological agriculture economy, reduces the environmental pollution, and prevents the ecological environment worsening.Because the relations of the agricultural ecology economic system and the external environment are complex, the agriculture emergy deliver is affected and the restricted by the various factors. In the basic of above counts of the computation, by the factorial analysis method using the SPSS software, analyze the influencing factor which is the emergy deliver the Anhui Province agriculture ecology economic system. The 11 data is analyzed which are annual rainfall in 1997 ~2008, the agricultural land area, the nitrogenous fertilizer, the phosphate fertilizer, the potassium fertilizer, the farm machinery gross power, the agricultural chemicals, the agricultural membrane, the diesel oil amount of use, the agriculture used electricity, agricultural labor force as the Anhui Province agriculture ecology economic system's major effect factor. After the operation, we discovered that among these influencing factor there are a more remarkable relevance, also explained that it is necessary to carry on the factorial analysis the. Then withdraw three latent common factors according to the factor loading, there are the social factor, the mix factor, the natural factor.Finally, make the forecast in the Anhui Province agriculture's recent development, and makes the suggestion of promotion development.
