Abstract

Abstract: In order to understand the current situation of carbon effect of land use in Huarong county and realize carbon emission reduction from the perspective of land use, the low-carbon optimization of land use structure was carried out to promote the low-carbon development of Huarong county’s economy. The carbon effect of the land use structure of Huarong county in 2006, 2012 and 2020 was estimated by mathematical measurement method, and then three optimization schemes of the low carbon land use structure at the end of the 13th Five Year Plan period were calculated by constructing the carbon effect evaluation index of the low carbon land use structure optimization and the multi-objective linear programming model. The scheme with the strongest comprehensive carbon accumulation capacity was selected as the optimal scheme. Under this low carbon scheme, 71 223.70 hm² of arable land, 8 744.80 hm² of garden land, 18 790.87 hm² of forest land, 19 569.94 hm² of other agricultural land, 14 207.55 hm² of residential land, 14 207.55 hm² of industrial and mining land, 1 329.83 hm² of land for transportation, 2 459.57 hm² of land for water conservancy facilities and 340.95 hm² of other construction land were selected. The comprehensive carbon storage of land use structure under this scheme was 514 900 tons more than that of 2020 plan, the area of garden land and forest land increased 249.12 hm² and 147.90 hm² respectively, and the area of construction land increased 155.88 hm². Under the optimized plan, the comprehensive carbon storage capacity of land use structure of Huarong county is better, which meets the requirements of low carbon economic development of Huarong county.

Key words: land use structure, low carbon economy, carbon effect, low carbon optimization, Huarong county
