摘要: 区域生态承载能力空间格局与优化研究是推动经济转型升级和生态保护修复统筹发展的需要。本研究以江苏沿海区域自然-社会-经济复合生态系统为研究对象,建立生态承载压力-状态-潜力(PSP)概念模型,用15项指标表征3个层面状态的交互关系,在GIS等空间技术支持下,通过分项和多项综合评价,分析研究区域生态承载力的量级、空间分异特征。结果表明: 江苏沿海区域分要素生态承载力适宜性的空间格局呈多种变化趋势,同一指标在不同市县的量级、面积、占比、布局等存在显著差异;从压力与状态叠加指数空间分异性可见,低压力适宜承载、低压力一般适宜承载、低压力不适宜承载、高压力适宜承载、高压力一般适宜承载、高压力不适宜承载的区域面积分别为3971.42、6885.21、3705.23、4597.03、6853.26、6403.97 km2,分别占总面积的12.3%、21.2%、11.4%、14.2%、21.1%、19.8%;状态与潜力叠加指数空间分异性结果显示,低潜力适宜承载、低潜力一般适宜承载、低潜力不适宜承载、高潜力适宜承载、高潜力一般适宜承载、高潜力不适宜承载的区域面积分别为3030.79、6545.30、5874.31、3253.31、7614.38、6097.83 km2,面积占比分别为9.4%、20.2%、18.1%、10.0%、23.5%、18.8%。在空间格局上大多呈现低压力承载区对应高潜力承载区、高压力承载区对应低潜力承载区的分布特征,压力与状态和状态与潜力之间存在相互影响、相互促进、协同提升的交互作用。

Abstract: The research on spatial pattern and optimization of regional ecological carrying capacity is especially necessary to promote the overall development of economic transformation, upgrading and ecological protection and restoration. This study chose the natural, social and economic complex ecosystem of Jiangsu coastal area as subject. The concept model of pressure-state-potential (PSP) of ecological carrying capacity was established. A total of 15 indices were used to represent the interaction of three level states. With the support of GIS and other space technologies, the magnitude, spatial variation of regional ecological carrying capacity were examined through comprehensive evaluation of multiple indices and analysis of single index. Results showed that the spatial pattern of the suitability of single factor ecological carrying capacity in Jiangsu coastal area showed a variety of trends. There were significant differences in the area, proportion and layout of the same index across different cities and counties. The spatial differentiation of pressure and state superposition index showed that low pressure suitable bearing, low pressure generally suitable bearing, low pressure unsuitable bearing, high pressure suitable bearing, high pressure generally suitable bearing, bearing high pressure unsuitable bearing area was 3971.42, 6885.21, 3705.23, 4597.03, 6853.26, and 6403.97 km2, accounting for 12.3%, 21.2%, 11.4%, 14.2%, 21.1% and 19.8% of the total area, respectively. The results of spatial differentiation of superposition index of state and potential showed that the area integral of low potential suitable bearing, low potential general sui-table bearing, low potential unsuitable bearing, high potential suitable bearing, high potential general sui-table bearing and high potential unsuitable bearing was 3030.79, 6545.30, 5874.31, 3253.31, 7614.38, and 6097.83 km2, accounting for 9.4%, 20.2%, 18.1%, 10.0%, 23.5% and 18.8% of the total area, respectively. Most areas showed distribution characteristics of low pressure bearing area corresponding to high potential bearing area and high pressure bearing area corresponding to low potential bearing area in spatial pattern. There was an interaction of mutual influence, mutual promotion and collaborative promotion between pressure and state superposition index and state and potential superposition index.
