摘  要：
基于2001年纵向岭谷区的遥感影像,将研究区划分为森林、草地、农田、湿地、水体、城镇、冰川7个一级景观类型,根据气候带、植被及地貌划分了26个二级景观类型,并利用中国陆地生态系统服务价值的研究成果,在GIS技术的支持下,对纵向岭谷区各景观类型的服务价值进行了研究.结果表明:纵向岭谷区总服务价值为5302.35×108yuan.a-1,占中国总服务价值的9.47%;在研究区提供的年服务价值中,土壤形成与保护的服务价值所占比例最高,占18.50%,其次是气体调节和生物多样性保护的服务价值;受景观类型分布广度和单位面积服务强度的综合影响,占研究区总面积66.11%的森林景观对区域总服务价值的贡献最大,贡献率达85.34%,其次为草地和农田景观.

摘  要：
Based on the RS image of Longitudinal Range-Gorge Region(LRGR)in 2001,the study area was classified into seven first-class landscape types(forestland,grassland,farmland,wetland,water body,urban land,and glacier),and 26 second-class landscape types in consideration of climate belt,vegetation,and topography.By using GIS technology,the services value of different landscape types of LRGR were studied in regards to the study results on services value of Chinese terrestrial ecosystems.The results indicated that the total services value of LRGR was 5 302.35×108 yuan·a-1,accounting for 9.47% of the whole country.The service value of soil conservation was the highest,which occupied 18.05% of the total services value,while the service values of gas adjustability and biodiversity protection ranked the second and third.Due to its distribution extent and services intensity per unit area,the forest landscape,which covered 66.11% of the total area,contributed most(85.34%)to the total service value of LRGR,followed by grassland and farmland landscapes.
