Study on Effects of Carbon Emission by Land Use Patterns of Shaanxi Province
摘要
Abstract
Taking Shaanxi province for example, based on the statistic area data of cultivated field, woodland, grassland and construction land, data of consumption of coal, oil and natural gas from 1989 to 2008 and the statistic data of different land use patterns in Shaanxi province in 2006, the paper analyzed the carbon emission of land use patterns by regression analysis,IDW-interpolation and Hopfield neural network. The results were as follows: (1) the total carbon emission was increasing at average speed of 178. 869 × 104 t/a in Shaanxi province from 1989 to 2008. (2) the main carbon sources were the construction land and cultivated field. The two main carbon sinks were woodland and cultivated field. (3) the amount of carbon emissions were different among regions in 2006: Guanzhong was the most one. Northern Shaanxi came next. The smallest one was Southern Shaanxi. Among cities of Shaanxi, Weinan was the highest one. Yangling was the lowest. (4) there was certain relationship between land use structure and carbon emissions. Land use patterns had a certain influence upon the carbon emission, and there are some mutual relations coexisted between them. When the proportion of woodland is constant, the more proportion of cultivated field and construction land accounted, the more quantities would be carbon emi sions. The more proportion of woodland accounted, the more carbon emissions would be decrease. Some suggestions about low-carbon were put forward in order to reduce carbon emission.关键词
