Circular Agriculture Structural Analyse Evaluate And Optimize For Village Scale

At present, the study about China's circular economic is common in the industrial and social development research, and to the agricultural cycle of the building, particularly for the larger proportion of the agricultural and rural studies are still a big gap. China's agriculture is the primary village as a unit of social organization, with more larger scale, the more intensive environmental pressure characteristics.Village-wide context has an independent socio-economic and geographical characteristics of the scope, structure relations at the village level, a clear, easy data collection, the agricultural cycle of the building is workable, agricultural production has been significantly linked characteristics, size and structure of agriculture agriculture at the grassroots level have a basic requirement of the agricultural cycle and conditions. Therefore, the agricultural circular of the rural grassroots administrative villages in the social, economic, ecological research, to promote the building of the Party Central Committee initiated a new socialist rural certain guidance.This article is basic of circulates the economical, the circulation agriculture elementary theory introduction, in view of the village scope circulation agriculture structure clear, theindustrial connection is close and so on the characteristic, puts into production the analysis method from the village level circulation agriculture system the research and the application, the village level circulation agriculture system sustainable development synthesis appraisal method research and the application, the village level circulation agriculture system multi-goals non-linearity optimization method and the heredity algorithm research and applies three aspects, carries on the exploration to the circulation agriculture from the different angle and the different method, proposes a mentality for the similar scope circulation agriculture research.Unifies Jiang Yan Jiangsu Province "the whole world 500" of Heheng village for the circulation agricultural development case, in view of its in 2001 , as the beginning of the Jiangsu Province agriculture circulation economicalexperiment site research the superiority, selects in 2001 and in 2004 years, to the river horizontal village agriculture system energy flow, the matter, the value flows the characteristic, the agricultural circulation pattern and the resources recurrent structure,the circulation agricultural economy sustainable development level,circulation agriculture structure aspect and so on optimized development structure carries on the discussion.It should discovers the similar scale and the structure circular agricultural development way.It get the result as following by study:(1) From analyse circular circular agriculture of input-output in Heheng village,since 2001,adjust continuously along with the circular agriculture construction in Heheng,the material circulation rate,energy circulation rate,nutriment matter circulation rate and value circular rate were increased.But along with structural adjustment in industry in farming, caused farming product processes industry's rate has the decreased.At the same time,the input-output during the farmland plants system,farming system and processing three systems of Heheng village,become the construction net relation.in the Heheng circular agriculture of wastes resources use,with making use of staw livestock dejection and processing waiting wastes as tache.(2) Compared circular agriculture sustainable development synthesizes with 2001 and 2004 in Heheng,it is increased 9.3% from 2001.In 2004,it is keeped that environment safety and produce the circulation index are better, can keep on the middle stage, but resources economy ,system synthesizes index just enter the stage of first step development, become that village circulation the agriculture can keep on the important bottleneck of the development.In 2004 Heheng village,circulation agriculture development obstacle factor is main to concentrate in clearly agriculture in the production, affecting agriculture produce quality.(3) After optimized circular agriculture structure of Heheng, it adviced that the plant of economy crop extends,especially the fruit product.The farming industry inside is high with the economic performance,the pollution of the environment is small,benefitting to the industry that offering plant,such as pig,chicken,ash swan that offer raising farming circulate the exploitation.Extend the green rice factory product,vegetables factory, the processing of livestock,can be better to circular primary commodity that make use of plant the industry, farming industry, increasing economic performance.Comparing 2004,it can keep on the development synthesizes the evaluation, excellent evaluate after turning the index number increases 8.3%, promoting in clear production, economy efficiently, system synthesizing etc classification index sign.So in ordre to developing the Heheng circulating agriculture,we must develop circulation agriculture as guaranting the agricultural product produce environment,then it would make ecosystem and economicly arrive unify.
