Function classification of ecological land in a small area based on ecosystem service bundles: a case study in Liangjiang New Area, China
Evaluation and management of ecological land (EL) are based on its proper function classification,which links closely with ecosystem service tradeoffs and synergies.The study of EL function classification in a small area may be a useful tool for improving the management of natural resource.In this study,we quantified 8 ecosystem services (ES),both ecological and social ones,in Liangjiang New Area,Chongqing,China.Based on the ES data,we identified 6 ecosystem service bundles based on hierarchical clustering analysis,and classified the bundles into 3 levels based on their relationship with key ecological processes and the importance of their service supply.Finally,we discussed the relationship between ecosystem service bundles and land use type,based on which we summarized the concept of EL and classified the land use type into 3 different levels of EL.The results showed that the function classification framework of EL based on ecosystem service bundles can express functional properties more comprehensively,as well as spatially quantify the relative proportions between different ecosystem services,which gives us a deeper understanding of the relationship between EL functions and land use types in small areas and provide guidelines for better ecosystem management.
