Research On Climate Carrying Capacity Evaluation Of Nanchang City

With the increasing global climate change,people pay more and more attention to the impact of climate change on human beings' production and life.The climate carrying capacity reflects the climate condition of a region and the research on the carrying capacity of climate becomes more and more important.Based on the existing research methods of climate bearing capacity index system and the present situation and characteristics of climate resources in Nanchang,this paper sets up an index system of climatic carrying capacity conforming to the current climate status of Nanchang City,Climate resources conditions,climate pressure conditions and climate sustainable development capacity of the three elements of 17 representative indicators selected to build the actual situation in Nanchang city climate carrying capacity evaluation index system.Through research,draw the following main conclusions:(1)The climate resource index(CR)of Nanchang City fluctuated between 1.02 and 1.53,with little change in the overall degree and a more stable trend.The maximum appeared in 2006 with a value of 1.53;the minimum value of the Climate Resources Index(CR)appeared in 2007 with a value of 1.02.(2)The Nanchang Climate Pressure Index(CS)shows a year-by-year upward trend from 2006 to 2015,which shows that the climate pressure in Nanchang City has been increasing year by year since 2006 and 2015.The climate stress index in 2015 It was 5.94.(3)The Nanchang Climate Sustainability Index(CD)has been increasing continuously from 2006 to 2015 and reached a maximum of 5.13 in 2015.However,there was a two-year decline in 2011-2013,mainly due to a decrease in spending on investment in ecological protection and environmental governance.(4)The climate carrying capacity index in Nanchang City shows a tendency of great fluctuation from 2006 to 2015.The values of CCI are all less than 1,which shows that the weather carrying capacity of Nanchang is not stable enough and the weather carrying capacity has not Reaching the target value.The minimum value of CCI appeared in 2013(0.39),which shows that the climate condition of Nanchang in this year is extremely optimistic.
