摘要
面对现有区域生态空间格局构建方法跨尺度研究较少、生态系统服务(以下简称"ESs")评价阈值设置存在不确定性和主观性、生态空间管控政策有待明确等问题,以川西北省级次区域为例,在测度水源涵养、水土保持、气候调节和生物多样性维护4项ESs供应水平的基础上,根据生态空间供应ESs的累计功能特征,提出生态系统服务重要性分级的评价方法,进行ESs重要性的单项和集成评价,识别四级生态优先区和两级生态廊道,构建符合生态战略一致性检验的区域生态空间格局,进而提出生态空间的分区管控政策。以期为跨尺度、跨区域生态空间格局提供理论和方法支撑。
Faced with problems such as rapid urbanization squeezing out ecological space and leading to a decline in the supply of ecosystem services(ESs),the existing methods for constructing regional ecological spatial patterns still have research gaps,such as few cross-scale studies,uncertainty and subjectivity in threshold setting,and ambiguous control policies.Taking the provincial sub-regions of northwestern Sichuan as an example,on the basis of measuring the supply level of four ESs of water conservation,soil and water conservation,climate regulation and biodiversity maintenance,it is the first time to propose the method for determining the importance classification evaluation based on the efficiency characteristics of the ESs supply of ecological space.On this basis,the importance of individual and integrated evaluation of the importance of the ESs is carried out.This paper then identifies four-level ecological priority areas and two-level ecological corridors,constructs a regional ecological spatial pattern that conforms to the consistency test of ecological strategies,and proposes targeted zoning management and control policies.It is expected to provide theoretical and methodological support for constructing a crossscale and cross-regional ecological spatial pattern that improves the supply capacity and efficiency of ESs.
