中文摘要:

      国土空间规划是统筹区域资源空间配置、开发管理和布局优化的总体方案,在引领区域协调发展上具有重要意义。国土空间规划必然导致土地利用类型及布局的改变,从而引起经济、社会、生态环境等方面的供给与需求变化。本研究从三生空间耦合协调的角度,通过生态系统服务和人类福祉需求的供需关系,揭示三生空间的供需连接与耦合关系。本研究借助 InVEST模型和生态服务价值当量法对生态系统服务供给与需求进行定量分析,同时引入耦合协调度模型与相对发展度模型,通过对生态系统服务供需变化进行耦合协调类型分析,探究国土空间用地结构调整所产生的供需间的协调关系,并用耦合协调状况对国土空间规划效益进行评价。研究发现,在规划期内宜宾市翠屏区生态系统服务供需总体耦合协调度呈现减小态势。2020-2035年耦合协调度从 0.60降低到 0.59,相对发展度由 1.05减小至 1.01。生态系统服务总体供给盈余明显,但由于供需分布空间差异,城镇地区为主要的供给赤字区域。影响生态系统服务需求的主要因素为环境净化需求,城市化指标对生态系统服务供需相对发展度具有较为普遍的负面影响。

英文摘要:

      Territorial spatial planning is an overall plan for coordinating the spatial allocation, development management and layout optimization of regional resources, which is of great significance in leading the coordinated development of the region. Territorial spatial planning will inevitably lead to the changes in land use and layout, which will lead the changes in supply and demand of economic, social and ecological environment. The research reveals the supply and demand connection and coupling relationship among the production-living-ecological space through the supply and demand relationship between ecosystem services and human welfare needs. The research uses the InVEST model and the ecological service value equivalent method to quantitatively analyze the supply and demand of ecosystem services, and using the coupling coordination degree model and the relative development degree model to evaluate the coupling effect. The methods was used in territorial space planning of Cuiping District in Yibin City. The study found that the overall coupling coordination degree of supply and demand of ecosystem services showed a decreasing trend during the planning period. From 2020 to 2035, the coupling coordination degree would decrease from 0.60 to 0.59, and the relative development degree would decrease from 1.05 to 1.01. The overall supply surplus of ecosystem services would be obvious, but due to the spatial difference of supply and demand distribution, urban areas would be the main supply deficit areas. The main factor affecting the demand for ecosystem services was the demand for environmental purification, and the urbanization index had a relatively common negative impact on the relative development of supply and demand of ecosystem services. The coupling and coordination of supply and demand of ecological services in regional territorial spatial planning should be evaluated, and the spatial characteristics and main problems of supply and demand of regional ecological services should be clarified, so as to make scientific and reasonable adjustments to the territorial spatial planning scheme and promote the orderly development of regional ecology and economy.
