[Abstract]:The land types of the five northwest provinces are divided into four categories (residential land, industrial and mining land, transportation land, agricultural land and water conservancy facility land and special land use), and the five northwest provinces of China (Shaanxi, Gansu, Qinghai Province) from 2002 to 2012 are adopted. Ningxia Hui Autonomous region, Xinjiang Uygur Autonomous region, this article is referred to as the five northwest provinces) energy consumption data and land use data, analysis of their land use and energy consumption, establish energy consumption carbon emissions model, Carbon footprint model and carbon efficiency evaluation model are used to measure the carbon emissions and carbon footprint of different land use patterns in 2002-2012. The results are as follows: from 2002 to 2012, the area of four types of land use types in five northwest provinces increased slightly, but the increase was relatively small. The order of area is as follows: agricultural land and water conservancy facility land area residential land and industrial and mining land area, traffic land area, special land area, According to the size of the area, the proportion of four types of land use types in the land use structure of the five provinces of Northwest China is 97.924, 1.916 and 0.156, respectively. The energy consumption in the five provinces of Northwest China showed an upward trend from 2002 to 2012. The total consumption increased from 6758.4593 脳 10 ~ 4 tce in 2002 to 12844.9583 脳 10 ~ 4 tce in 2012, with an average annual growth rate of 7.49.The raw coal, coke, crude oil, gasoline, kerosene, diesel oil, fuel oil, liquefied petroleum gas, dry gas from refineries, The average proportion of natural gas consumption in ten fossil energy sources is respectively: 54.57 / 13.95 / 3.16 and 6.69 / 1.24 / 12.82 / 1.67 / 1.80 / 1.69.3The total carbon emissions from 2002 to 2012 in the five provinces of Northwest China showed a fluctuating growth state. From 3978.6034 脳 104t in 2002 to 9366.1771 脳 104t in 2012, the increase was 135.41, and the average annual growth rate was 9.26.The carbon emission of Shaanxi, Xinjiang, Gansu, Ningxia and Qinghai was in turn. The corresponding annual growth rates are respectively: 1 / 16.25 / 7.50 / 7.56 / 10.35 / 10.11. The carbon emissions of different land use patterns are as follows: residential areas and industrial and mining land, land for transportation, land for agriculture, land for water conservancy facilities, land for agriculture, and land for water conservancy facilities. The corresponding proportions of total carbon emissions are respectively: 8 / 82 / 11.83 / 3.16 / 3.01, with an average annual growth rate of 9: 54 / 16.54 / 3.56 / 3.56 respectively) the overall intensity of carbon emissions from the four types of land use in the five provinces of Northwest China shows an overall upward trend. The order of carbon emission intensity of four types of land is as follows: special land, traffic land, residential land, industrial and mining land, agricultural land and water conservancy facility land, The average annual growth rate according to carbon emission intensity is respectively:: 27.590.10.800.3.14 and 9.23.5.The best ranking of total efficiency of land use carbon efficiency in five northwest provinces is: Qinghai, Xinjiang, Xinjiang, Gansu, Shaanxi, Ningxia, Ningxia, Shaanxi, 2002 to 2012, on the basis of investment in energy consumption. To achieve the best output, Gansu is mainly constrained by technical efficiency. Shaanxi and Ningxia reached a valid value of technical efficiency in 2007 and 2009. At present, they are seriously constrained by scale efficiency, and Xinjiang has reached the best output, total efficiency and technical efficiency in 2012. The scale efficiency is 1. Before 2012, the carbon footprint of the five provinces in Northwest China has been fluctuating and rising. The biggest carbon footprint in the province is Xinjiang, followed by Gansu, Shaanxi, Ningxia and Qinghai. The carbon footprint of the four types of land use is as follows: residential land, industrial and mining land, agricultural land and water conservancy facility land special land, corresponding to the proportion of the total carbon footprint is 82.34%, 11.33 and 3.40 and 2.933 respectively, and the average annual growth rate is 10. 33%, 16.48%, 0.20 and 17. 35%, respectively.The average annual growth rate is 10. 33%, 16. 48% and 0. 20% and 17. 35% respectively.
