摘要: 为了解华容县土地利用的碳效应现状,从土地利用的角度实现碳减排,对土地利用结构进行低碳优化,促进华容县经济的低碳发展。采用数学计量方法估算出华容县2006年、2012年、2020年3期规划年份的土地利用结构的碳效应状况,再构建低碳土地利用结构优化碳效应评价指标、建立多目标线性规划模型计算出华容县十三五规划期末的低碳型土地利用结构的3种优化方案。选取综合碳蓄积能力最强的方案作为最优方案,在此低碳方案下耕地71 223.70 hm2、园地8 744.80 hm2、林地18 790.87 hm2、其他农用地19 569.94 hm2、居民点及工矿用地14 207.55 hm2、交通运输用地1 329.83 hm2、水利设施用地2 459.57 hm2、其他建设用地340.95 hm2。该方案下土地利用结构的综合碳储量比2020年规划方案增加了51.49万t,园地和林地面积分别增加了249.12 hm2和147.90 hm2,建设用地面积也增加了155.88 hm2,优化方案下的华容县土地利用结构的综合碳积蓄能力较好,符合华容县低碳经济发展的要求。

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
