摘　　要：生态功能分区综合反映了区域自然生态功能的特征差异,是自然资源开发和生态环境保护空间差异化管治的重要依据。针对以往生态功能分区分析框架复杂多样、权重设定人为主观等问题,本文以云南省大理白族自治州为例,基于要素-结构-功能系统分析框架,从基底要素-干扰结构-主导服务三方面构建指标体系,运用自组织特征映射(SOFM)神经网络依次进行流域主导生态系统服务分区、基底要素分区、干扰结构分区和生态功能综合分区,最终将大理州划分为4个生态功能区和10个生态功能亚区。不同要素分区对比结果表明,大理州生态功能综合分区主要受主导生态系统服务制约,二者重叠率达79.98%。本研究基于要素-结构-功能分析框架,系统刻画了区域生态系统结构与功能特征及其空间差异,为生态功能分区提供了新的方法指引。Ecological function zoning comprehensively reflects the different characteristics of re- gional ecological function, which is an important basis of differentiated spatial governance to nat- ural resource development and eco-environmental protection. Aiming at the existent problems of the multiple analytical framework and subjective and complicated weighted value in previous eco- logical function zoning, the ecological function zoning of Dali Bai Autonomous Prefecture was car- ried out based on systematic analysis framework of element-structure-function. An index system was constructed from three aspects of basal element, interference structure, and dominant ser- vices. By the application of SOFM, ecological service zoning, basal element zoning, interference structure zoning, and comprehensive ecological function zoning were conducted. Finally, Dali Bai Autonomous Prefecture was divided into 4 ecological function zones and l0 ecological functional sub-zones. Through comparing the different zones, it was found that the comprehensive ecological function zoning was mainly controlled by the zoning of primary ecosystem services, with an over- lapping rate of 79.98%. By adopting the framework of element, structure, and function, this study systematically described the characteristics and spatial difference of regional ecosystem structure and function, providing a new approach for the zoning of ecological function.
