摘　　要：生态系统服务之间通常呈现权衡或协同关系,然而有研究表明它们之间还存在着一种新的约束关系。由于喀斯特地区环境的空间异质性,已有关于非喀斯特地区生态系统服务约束关系的研究结果可能不适用喀斯特环境。以约束线方法结合限制性立方样条分析,探讨了典型喀斯特山区贵阳市的生态系统服务两两之间的非线性约束关系。研究结果显示,养分保留量-产水量呈正凸型曲线约束关系,土壤保持量-产水量和土壤保持量-养分保留量呈负凸型曲线约束关系,生境质量-产水量和生境质量-土壤保持量呈驼峰型曲线约束关系,生境质量-养分保留量呈凸型曲线约束关系。Ecosystem services usually exhibit trade-offs or synergies relationships with each other;however,there is also a new type of constraint relationship between them.Due to the spatial heterogeneity of the environment in karst regions,existing findings on constraint relationships of ecosystem services in non-karst areas may not be applicable to karst environments.We explore the non-linear constraint relationship between two pairs of karst ecosystem services using the constraint line method combined with restricted cubic spline analysis.The results show that nutrient retention-water yield showed a positive convex curve constraint relationship,soil conservation capacity-water yield and soil conservation capacity-nutrient retention showed a negative convex curve constraint rela⁃tionship,habitat quality-water yield and habitat quality-soil conservation capacity showed a hump-shaped curve constraint relationship,and habitat quality-nutrient retention showed a convex-waved curve constraint relationship.
