采用频度法对喀斯特生态系统服务类型及指标进行分析，结合中国南方喀斯特环境特征、生态功能区位等因素，构建了石漠化生态系统服务价值评估指标体系；并以贵州花江示范区为例，基于实测和调查数据，采用物质量和价值量相结合的方法对其2010年生态系统服务价值进行评估。结果表明：示范区生态系统服务价值为19604.71万元。其中，固碳制氧价值11181.25万元、土壤肥力价值3051.56万元、产品供给价值为2850.40万元、涵养水源价值2521.13万元、土壤保持价值为0.37万元。示范区生态系统服务价值以间接价值为主，占85.5%，直接价值仅占14.5%；生态功能价值主要依靠灌丛、经济林、耕地和疏林生态系统提供，裸岩荒坡尽管是研究区的优势景观，但提供服务价值较低。
採用頻度法對喀斯特生態繫統服務類型及指標進行分析，結閤中國南方喀斯特環境特徵、生態功能區位等因素，構建瞭石漠化生態繫統服務價值評估指標體繫；併以貴州花江示範區為例，基于實測和調查數據，採用物質量和價值量相結閤的方法對其2010年生態繫統服務價值進行評估。結果錶明：示範區生態繫統服務價值為19604.71萬元。其中，固碳製氧價值11181.25萬元、土壤肥力價值3051.56萬元、產品供給價值為2850.40萬元、涵養水源價值2521.13萬元、土壤保持價值為0.37萬元。示範區生態繫統服務價值以間接價值為主，佔85.5%，直接價值僅佔14.5%；生態功能價值主要依靠灌叢、經濟林、耕地和疏林生態繫統提供，裸巖荒坡儘管是研究區的優勢景觀，但提供服務價值較低。

This paper using frequency method, elaborates analysis on evaluation index system of karst ecosystem service value. Taking Huajiang Gorge of Guizhou Province as example, we have constructed the evaluation index system of rocky desertification ecosystem service value which is sourced from environment characteristics, ecological function location and other factors. And on the basis of actual survey data, we have used the physical and value assessment methods to evaluate ecosystem service value of Huajiang gorge in 2010. The results show that: The overall ecological service value of the demonstration area was 196 047.1×103 Yuan, consisting of 111 812.5×103 Yuan of CO2 solidification and O2 release value, 30 515.6×103 Yuan of soil fertility value, 28 504×103 Yuan of product supply value, 25 211.3×103 Yuan of water conservation value, and 3.7×103 Yuan of soil conservation value. The indirect values contributed the most to the overall value of ecosystem services, which accounted for 85.5% of the total, while the direct values accounted for only 14.5%. Ecological function value was mainly provided by shrub, economic forest, farmland and woodland ecosystems, and the bare rock slopes showed low service value, though they were the dominated landscapes in the study area.
