Comparative Study Based On The Bifferent System Simulation Model Kiwifruit Orchard Ecosystem Carbon Sink Capacity

The problem of global warming, has become the current domestic surgical an academic topic. Most of the meteorological expert thinks that greenhouse gas, particularly the CO2concentration increase caused by climate warming. At the same time, climate warming may also cause some extreme weather events occurred, followed is to be the global ecological problems, human production and life caused great threat. Therefore, the current carbon emissions, carbon pools and other related issues become the focus of research in academic circles.Sure our country agriculture orchard ecosystem carbon sequestration capacity of comparative study of different kiwifruit orchard ecosystem carbon sequestration capacity, to promoting our country agriculture orchard ecosystem carbon sequestration capacity to seek better methods. At the same time for China to establish and implement the corresponding measures to reduce emissions as well as through carbon trading to make industry carbon, all has the significance and contribution.This article in the mountain areas around the Ya’an city county, the choice of traditional retail planting and agricultural enterprise scale planting two different patterns of Kiwifruit orchard. Through field investigation and sampling of soil, plant sampling analysis, on two different kiwifruit orchard ecosystem carbon source/sink carbon emissions, carbon sequestration and net carbon sink were identified and estimated and compared. On the basis of introducing the concept of system dynamics, with the method of system simulation modeling, macro, quantitative, dynamic prediction of two different kiwifruit orchard ecosystem carbon sequestration capacity over the next10years the size and change trend. Research results show that:1,The traditional retail cropping patterns exist fertilizer discharge CO2, kiwi fruit orchard with infrastructure construction energy consumption emissions of CO2, agricultural waste, the use of pesticide emissions CO2, transport and packaging energy emissions CO2, agricultural and mechanical energy emissions CO2carbon source emission point. With the traditional retail planting mode photograph is compared, dimensions is changed cultivate model increased irrigation, energy consumption emissions of CO2two emission of carbon source.2,The traditional retail planting patterns of carbon sources, kiwi fruit plant surface biomass, and soil organic carbon. The scale of the carbon source and traditional retail roughly the same, but compared with the traditional retail planting mode, ground biomass model compared to the single, forest not interplanting other crops, surface biological only weeds.3,The scale of planting mode of kiwifruit orchard ecosystem carbon reserves is9046(kgC/667m2), carbon is7066.29(kgCO2/667m2). A value of two to offset each other, a net carbon sink is1979.71(kgC/667m2). While the traditional retail under planting mode of the carbon reserves is8964.77(kgC/667m2), carbon is4702.36(kgCO2/667m2). A value of two to offset each other, a net carbon sink value of4262.41(kgC/667m2). Therefore, the traditional retail planting mode is more beneficial to kiwifruit orchard ecosystem carbon sequestration capacity.4, Use a system kinetic method and principle, build a consists of seven modules (demographic factors, yield status module, module of kiwi kiwi income module, kiwi fruit, kiwi and emission reduction energy consumption module, management module, input module of kiwifruit Actinidia carbon sink module) consisting of the simulation model, the simulation of future carbon sequestration capacity. Through continuous modification, debug, test prove that the model is feasible, and can be used to support a system simulation.5,In two different planting patterns of kiwifruit orchard ecosystem carbon sequestration capacity simulation data show that, in the future10years in two different planting patterns of carbon growth potential were gradually rising trend. Relatively speaking, the future of the traditional retail under planting mode of kiwifruit orchard ecosystem carbon sequestration capacity.6, From the perspective of traditional retail carbon sequestration, planting pattern has an advantage more, but from the research data show that economic benefit, the traditional retail under planting mode of average per667m2kiwifruit orchard economic income is3250yuan, and the scale of planting patterns on average every667m2kiwifruit orchard economic income is4300yuan. The scale of the economic benefits of planting pattern was significantly higher than that of traditional retail planting pattern.For carbon sequestration and economic balance point, so that the carbon sequestration and economic benefits to achieve a win-win situation. According to the modern agricultural development on a moderate scale of the trend set out, is recommended in the large-scale cultivation of Kiwifruit in the process, some in favor of a net carbon sink of cultivation and management measures. For example, adjustment of kiwifruit orchard cultivation mode; apply farmhouse fertilizer; straw return Lin and other measures.
