摘要
以锡林郭勒草原自然保护区为例,采用谢高地等人的草地生态系统服务功能价值评估方法,利用2005年的研究区专题绘图仪(TM)遥感影像数据和单位面积平均产草量数据,评估草原生态系统服务功能价值,并计算出研究区不同土地利用类型的气体调节、气候调节、水源涵养、土壤形成与保护、废物处理、生物多样性保护、食物生产、原材料生产、文化娱乐等9种生态服务功能的经济价值。得出结论:(1)2005年研究区生态系统总服务价值为63.41亿元;(2)草地服务价值占到研究区总服务价值的80%,其平均单位面积服务价值高于耕地和荒漠;(3)生态系统各种服务功能的价值差别较大,间接使用价值是直接使用价值的16倍。
Taking Xilinguole grassland natural reserve as an example, this paper adopted ecosystem service value (ESV) assessment for grassland proposed by Xie Gaodi et al.. Grassland ESV was evaluated employing TM remote sensing image and average grass production per unit area in the study area in 2005. Meanwhile, the economic value of 9 types of ecosystem services were assessed, including gas and climatic regulation, water conservation function, soil formation and protection, waste disposal, biodiversity protection, food and raw material production, as well as culture and entertainment. The results showed that: 1) total ESV of study area reached 6.341 billion Yuan in 2005; 2) the service value of grassland accounted 80% in total ESV with higher per unit area service value than crop field and desert; 3) there were significant differences in value among ecosystem services and indirect useable value was 16 times higher than the direct.
