The Material Circulation Of Farmland Ecosystem And Management Countermeasures Based On Peasant Households

Ecosystem of cropland is a significant basic unit to coordinate the nexus between rural resources and environment,economy and society.Farmer's ecosystem is an important basic unit to coordinate the development of farmland ecosystem.Based on ecology theory and energy flow analysis and emergy analysis and swot analysis and precision poverty analysis architecture,from the perspective of energy flow,we analyzed farmers'production decision data of investigation covered 222 typical households form 10 villages and the related data of emergy analysis from the 67 precise poverty households in xinhua township in tianquan county of Ya'an city in the hilly area of Basin and mountainous area.Energy flow and emergy analysis indicators are used to evaluate the current situation of Xinhua Township in Tianquan County Ya'an City mountain basin.The results show that farmland ecosystem is a multi-operational system that is not only an essential traditional agriculture but also a modem agriculture.Due to low total supple mental and organicenergy input in agricultural system,sutilization efficiency,hence energy output levels are low increasing total supple mental and organic energy input can improve energy transformation efficiency,hence enery output levels.Energy relationship between pri:mary and secondary produttion systems is in disharmony,with large energy deviation that not only results in serious organic energy waste but also equaly brings about scarcity in the souses of organic fertilizer.For the specific results are as follows:Through a series of empirical and analytic process,the main conclusions of this study are as follows:First,effective input and capacity energy,solar energy use efficiency,energy cycling index and membership function value.The results showed that the region of in xinhua township in tianquan county of Ya'an city in the hilly area of Basin and mountainous area is wholly at high input with high output agricultural production level,which in the trend of energy input constructure with highly homoplasy,causing excessive investment of industrial chemistry input energy and a wasting of resource utilization;Second,As for input energy composition of projects,the dominant position of used amount are taken by chemical fertilizer,pesticides,organic fertilizer,agricultural mechanization level has an insignificant appearance;Compared with under the no scale management mode ecological region,Under the scale management mode ecological region has a obviously advantage in both energy utilization efficiency and economic benefit in the same paddy-upland rotation pattern,the production capacity of different pattern is affected by regional disparity as well as aspect of cultivated crop in dry season;Third,according to the comprehensive assessment of 8 patterns via energy flux status,we found that the wheat-rice rotation pattern in Farmland ecosystem management model driven by leading enterprises shows its optimal benefit over others for obtaining higher energy,resource utilization efficiency and material output.Last,essential and reasonable countermeasures based on the study contribute to developing rotation agriculture in Sichuan are put forward,energy flux and direction ought to be enhanced properly,expanding the crop area to acquire scale economics effect.at length,updating the field corp cultivation tech with the modem,information and precision way.fourth,Tianquan County Xinhua Township farmland ecological system belongs to the growth type strategy;Fifth,The industry auxiliary energy ratio and organic auxiliary energy are 0.87 and 0.095 respectively.The 67 typical households are much higher than the later,indicated that this fanning ecological system relied mainly on the industry auxiliary energy such as chemical fertilizer,electricity and they will do harm to the environment.However,the famer family didn,t make full use of the organic fertilizer which is environment friendly.For this reason,the increasing of the input of organic auxiliary energy will enhance the economic benefit and the sustainable development degree of this ecosystem.Finally,form the aspects of optimizing resource Allocation and improving energy consersion efficiency.foremost,promoting the recycle utilization of energy by all means,environment friendly biomass energy source should be extended widely.
