- Abstract:
- The change of land use is the main factor influencing the regional carbon emission, the inappropriate development of the land use will break the local carbon balance. This paper analyzes the carbon emission effect for the different land uses in Ningxia in the past 16 years on the basis of the land use data and energy consumption data of Ningxia from 2000 to 2016. The results show that:(1)the carbon emission of the land use in Ningxia increased, and the increasing rate reaches to 199.11%, while the increasing level is getting slower after year of 2012;(2)from 2000 to 2002, the largest carbon source was farm land in Ningxia; from 2002 to 2016, the largest carbon source was construction land in Ningxia; the largest carbon sink is woodland, the increased carbon absorption of woodland was less than the increased carbon emission of construction land, and the increase of the construction land is the main factor causing carbon commission;(3)the index of carbon emission by land use increased every year, and the increasing level was getting slower after year of 2012; the index of carbon emission pressure declined in 2012 after reaching the peak value, showing that the energy conservation and emission reduction had the positive effect on the environment in the process of economic development after year of 2012;(4)the key point of carbon emission reduction in Ningxia is to increase the coverage rate of woodlands and grazing land and improve the carbon absorption ability greatly when reducing the carbon emission of construction land and farm land.
