摘要：根据森林生态系统结构与功能特征,探讨森林资源二类调查资料与定位观测资料相结合的森林生态系统服务功能评价方法,并以秦岭火地塘林区为例,将有林地小班按优势树种划分为12个林分类型,并对各林分的供给功能、调节功能、文化功能和支持功能进行评价。研究结果表明:(1)1990年火地塘林区森林生态系统服务功能价值总量为877.28万元·a^(-1),单位面积价值量为469 1元·hm^(-2)·a^(-1),其中产品服务价值为613元·hm^(-2)·a^(-1),调节功能价值为103 8元·hm^(-2)·a^(-1),文化功能价值为52元·hm^(-2)·a^(-1),支持功能价值为298 8元·hm^(-2)·a^(-1),总的生态效益是经济效益的6.65倍。(2)不同林分类型之间以及生态系统的不同服务功能之间,功能与价值均存在较大差异,阔叶树种的服务功能要高于针叶树种,其中杨类总的生态系统服务功能价值最高(809 9元·hm^(-2)·a^(-1)),冷杉林总的生态系统服务功能价值最低(264 8元·hm^(-2)·a^(-1)),并且生态系统的支持功能明显高于其它服务功能。
According to the characteristics of structure and function of ecosystem, evaluating methods of the ecosystem service based on the combination of the class Ⅱ investigation to forest resource and long-term fixed observation data were discussed. At the same time, 12 types of forest ecosystem were divided at Huoditang forest region according to the predominance tree species and the function and value of different forest types, such as provisioning services, regulating services, cultural services and supporting services were assessed. The results showed that： （1）In 1990, the total value of ecosystem services at Huoditang forest region was 877.28×10^4 yuan ·a^-1 , about 4 691 yuan^-2 ·hm^-2· a^-1 , the values of provisioning, regulating, cultural, and supporting services was 613 yuan^-2 ·hm^-2· a^-1, 1 038 yuan^-2 ·hm^-2· a^-1, 52 yuan ^-2 ·hm^-2· a^-1, and 2 988 yuan ^-2 ·hm^-2· a^-1 respectively. The overall economic value of ecosystem services was 6.65 times as much as the value of provisioning services （2）There had a difference between different forest types and different forest ecosystem services. The services of broadleaved species were higher than those of conifer species. The value of Populus ecosystem services was the highest, about 8 099 yuan ^-2 ·hm^-2· a^-1. The value of Abies fargesii ecosystem services was the lowest,about 2 648 yuan ^-2 ·hm^-2· a^-1. The supporting services of the ecosystem were higher than other services.
