摘要

This paper combined with the national land use, ecological environment and the desert in northern ningxia selecting distribution GIS map data biome, mathematical model is established as a case study of yinchuan, we collected 2006-2015 in yinchuan carbon oxygen consumption, land utilization, GDP, population, urbanization rate, gross industrial production. First through the carbon and oxygen balance factor analysis and the analysis of decoupling relationship between carbon and oxygen consumption, it is concluded that the relationship between economic system and ecological system of yinchuan, yinchuan judged by Pearson carbon oxygen consumption coefficient method and the correlation of other related, choose one of the strong correlation indicators, multiple linear regression equation to establish carbon oxygen consumption. Through the analysis of land use in Yinchuan by ecosystem value service model, the carbon sequestration and oxygen release of each type of land are calculated, and the difference between carbon sequestration and oxygen consumption is analyzed. The grey system prediction model is used to predict the GDP, population, urbanization rate, industrial GDP and other indicators of Yinchuan in 2022, so as to conclude that the carbon emission in 2022 is 20.716,600 t and the oxygen consumption is 2.4065,400 t. According to the GIS map of desertification, biology and reservoir of Yinchuan city, the ecological area was planned and the land type was planned. After calculation, the planned carbon sequestration was 29.1586 million T and the oxygen release was 2.406539 million T. After planning, the carbon sequestration was 8.445 million T and the oxygen release was 7.7016 million T.
