摘要
“三生”空间转型的碳储量效应及其空间分异特征是指导区域国土空间开发与生态环境保护的重要依据.基于人地关系理论,运用动态度模型、变化轨迹方法探析了北京市“三生”空间分布格局和转型特征,借助InVEST模型和生态环境质量贡献率揭示了北京市1980~2020碳储量时空分异特征和“三生”空间转型对碳储量的影响.结果表明:(1)在人类文明发展阶段,人为诱导和自然转化两种转型方式呈现相互演替趋势;(2)1980~2020年北京市“三生”空间结构主要以生态空间为主,农业生产空间呈持续减少趋势,城镇生活空间则主要分布在主城六区;(3)40年间“三生”空间转型剧烈,人为诱导引起的转型变化占所有转型变化面积92.68%;(4)1980~2020年北京市碳储量高值区域分布在生态涵养区,农业生产空间和草地生态空间转向林地生态空间是碳储量增加的主要原因,相反,城镇和农村生活空间对生态空间的侵占是碳储量减少的主要原因.
Since the carbon storage effect and spatial differentiation characteristics of"production-living-ecological"space transformation were the important basis for guiding regional land spatial development and ecological environment protection,the spatial distribution pattern and transformation characteristics of"production-living-ecological"space in Beijing were analyzed by using dynamic attitude model and change trajectory method based on the theory of man-land relationship,while the spatial differentiation characteristics of carbon storage in Beijing from 1980 to 2020 and the influence of"production-living-ecological"space transformation on carbon storage were revealed by means of InVEST model and contribution rate of ecological environment quality.The results showed that:In the development st①age of human civilization,the two modes of transformation,artificial induction and natural transformation convey a mutual succession trend;②From 1980 to 2020,the spatial structure of"production-living-ecological"space in Beijing was mainly ecological space,and the agricultural production space was decreasing continuously,while the urban living space was mainly distributed in the six districts of the main city;③During the past 40 years,"production-living-ecological"space had undergone drastic spatial transformation,and the transformation and changes caused by human activities accounted for 92.68%of all the transformation and changes;④From 1980 to 2020,the high-value areas of carbon storage in Beijing were distributed in ecological conservation areas,and the main reason for the increase of carbon storage was the shift of agricultural production space and grassland ecological space to woodland ecological space.On the contrary,the occupation of ecological space by urban and rural living spaces was the main reason for the decrease of carbon storage.
