摘要

[目的] 基于区域关键生态系统服务，研究西藏自治区生态功能区划，为高原生态系统的区域综合认知和空间综合治理提供科学依据。[方法] 在GIS技术支持下，基于区域关键生态系统服务功能构建西藏生态功能分区指标体系，运用自组织特征映射（SOFM）网络聚类栅格单元指标，并基于小流域单元逐步合并破碎化的聚类结果来确定生态功能区边界。[结果] ①区域内各生态系统服务功能指标整体上呈现出从东南向西北递减的格局；②根据各分类栅格的景观聚集度指数确定最优分类数为5类；③破碎化的5种聚类结果经过子流域单元的合并而最终被划分为5个生态功能区。[结论] 根据各区域生态系统特征进行命名，划分出藏北高寒荒漠草原生态脆弱区、藏中草原牧业盈余区、藏东亚热带山地针叶林农牧产品供给区、藏东南亚热带山地针叶林产水区和藏东南热带季雨林生物多样性保护区5个生态功能区。

Abstract

[Objective] Based on the regional key ecosystem services

the regional ecological function regionalization of Tibet Autonomous Region was studied to provide basis for the regional comprehensive cognition and spatial comprehensive management of the plateau ecosystem. [Methods] With the support of GIS technology

the index system of ecological function partition in Tibet was constructed based on the regional key ecosystem service. Using the self-organizing feature mapping (SOFM) clustering grid cell index

the boundary of ecological functional area was determined by merging small watershed cells. [Results] ① The ecosystem service function index exhibited a notable decreasing gradient from the southeast to the northwest. ② According to the landscape aggregation index of each classification grid

the optimal classification number was five. ③ The fragmented five clustering results were finally divided into five ecological function areas after the merger of small watershed cells. [Conclusion] According to the characteristics of each regional ecosystem

the five ecological functional areas including: the ecologically fragile alpine desert grasslands in Northern Tibet

the animal husbandry surplus areas in Central Tibet region

the agriculture and animal husbandry product supply areas in East Asia tropical mountain coniferous forests

the water production areas in Southeast Asia tropical mountain coniferous forests

and the biodiversity protection areas in Southeast Tibet tropical seasonal rain forests.
