新兴发展区域土地低碳利用结构优化研究——以广西北部湾经济区为例

土地利用结构优化是引导区域经济社会的低碳发展的重要途径.以广西北部湾经济区为例,在低碳经济背景下,采用灰色预测和灰色线性规划相结合方法,对新兴发展区域现行土地利用总体规划进行优化.结果表明,现行土地利用总体规划在减缓碳排放、增加碳蓄积方面都有优化潜力,林地、城镇工矿和农村居民点用地规模与碳排放效应密切相关.提出应当注重通过调整土地利用结构减缓土地利用碳排放的作用,引导土地开发模式的低碳化;规划调整需要大力保护林业用地,适度增加林地数量;在保障社会经济发展的基础上,严格控制建设用地的无序增长,削减农村居民点规模.

Structural optimization of low-carbon land use in newly-developing regions A case study of Guangxi Beibu Gulf economic zone

Optimizing land use structure is an important way to lead low-carbon in regional economy development.In the circumstance of low carbon economy, taking Guangxi Beibu Gulf economic zone as an example, GreyPrediction and Grey Linear Programming were used to optimize the comprehensive land use planning in the newlydevelopingregions. The results shows that based on the current land use planning, there is a potential in mitigatingcarbon emissions and increasing carbon storage. In addition, the scale of forest land use, urban industrial land useand rural residential land use is closely related to the effect of carbon emissions. The paper also put forward thatpeople should pay attention to mitigating the effect of land-use carbon emissions by adjusting the land use structureand guiding low-carbonization land development mode. These adjustments ask human to try great efforts in protectingforest land and restricting moderately increase in forest land use. Besides that, on the base of the protection of socialeconomy development, people should strictly control the randomly growth of construction land and reduce the scale ofrural residential region
