Nanzhao Country Land Use Carbon Source Carbon And Its Change Analysis

At present,global warming has became a fact of life,and man-made greenhouse gases(mainly forthe CO2and CH4) emissions are the main factors of greenhouse, according to the IPCC’s prediction,greenhouse gas emissions will lead to the average global temperature increase of0.2℃every10years(IPCC,2001). In the long run, human beings rely on the earth will be born because of increased greenhousegases with rising sea levels, glaciers, climate extreme events such as natural disasters and damaged survivalenvironment also deteriorates.The study found that in recent years, the land use change of ecological system carbon emissionsare closely linked. Based on the land use change on carbon source carbon sink influence as a starting point,a quantitative method to NanZhao county8years of land use of the time and spatial change and its carbonsource article analyzes the influence of carbon, and combined with a new round of land use planning for thefuture NanZhao county of carbon source carbon amount forecast. The main analysis results are:(1)8years of the main land use types NanZhao county happened certain change, of which,cultivated area increased by0.25%, the land use change rate is1.89%, the land use dynamic for0.04;Forest area increased by0.59%, the land use change rate is0.91%, the land use dynamic for0.02;Construction land reduced0.01%, use the land for construction land use change rate is0.2%, the land usedynamic for0.03.(2) NanZhao county2003to2010total carbon source from69700tons to147400tons of increase,the average changing quantity is9700tons, the change to a larger extent, is mainly due to construction landcarbon emissions of the increased; Carbon amount on the whole show the trend of increasing year by year, from736200tons to748600tons of increase, the average changing quantity is1500tons, the variation isnot obvious, the largest amount of carbon contribution is forest land; Net carbon emissions from-from666600tons of increased to601100tons. To all carbon emissions intensity from2.33t/(hm2*a) increasedto5.03t/(hm2*a), carbon emissions per unit of GDP strength from0.18t/(hm2*a) reduced to0.16t/(hm2*a).(3) Based on a new round of the NanZhao county general land use planning "predict NanZhaocounty of carbon source in2020to151200tons, an increase of6500base than planning tons, more than2010years to add3800tons; Carbon to16500tons, an increase of37500base than planning tons, morethan2010years to add27400tons, net carbon emissions is planning to reduce the ams31000tons,compared with2010reduced23600tons.Finally, according to the relevant analysis results, this paper puts forward the technology andpolicy aspects of land use of the future Suggestions and countermeasures, and points out that needs furtherresearch related issues.
