摘　　要：为更加直观地了解维西森林生态系统服务功能价值,更好地保护维西森林植被,以云南省维西傈僳族自治县(简称维西县)为研究区,借助GIS空间分析,从林分尺度评估森林生态系统服务功能价值,根据现行的森林生态系统服务功能评估规范,并结合当地森林生态系统实际情况,以此制作可视化专题地图,分析其空间格局。结果显示:维西县单位面积森林生态系统服务功能价值9.31×10^(4)元/(hm^(2)),总价值335.91×10^(8)元/a;维西县森林生态系统的主要服务功能为涵养水源、生物多样性保护和固碳释氧;松杉林的服务功能价值相对高于其他林分,以云南松林价值最高;维西县森林生态系统服务功能价值存在明显的空间异质性,整体上呈现中部高四周低的分布格局,各乡镇以塔城镇价值最高。研究表明,维西县森林生态系统服务功能价值远高于全国和全省水平;不同服务功能与林分类型价值呈现较大差异,且整体上呈现空间异质性格局。This study aims to gain a comprehensive understanding of the service value of the forest ecosystem in Weixi county of Yunnan Province and protect it.By using GIS spatial analysis,the value of forest ecosystem service functions is evaluated at the stand scale based on forest ecosystem service function evaluation standards and combined with the actual situation of the local forest ecosystem.The results show that the forest ecosystem service value per unit area in Weixi County is 9.31×10^(4)yuan/(hm^(2)·a),with a total value of 335.91×10^(8)yuan/a;The main service functions of the forest ecosystem in Weixi County are water conservation,biodiversity protection,and carbon sequestration and oxygen release;The service function value of pine and fir forests is relatively higher than that of other forests,with Yunnan pine having the highest value;There is significant spatial heterogeneity in the value of forest ecosystem service functions in Weixi County,with a distribution pattern of high in the central region and low in the surrounding areas.The value of Tacheng Town is the highest among all townships.This study indicates that the value of forest ecosystem service functions in Weixi County is much higher than the national and provincial levels;There are significant differences in the value of different service functions and forest types,and overall,there is a spatial heterogeneity pattern.
