中文摘要	以19952015年5期Landsat系列遥感影像为主要数据源,依据改进的当量因子法对龙门山地区生态系统服务价值进行核算并进行了敏感性分析。结果表明:(1)19952015年各类生态系统中森林生态系统服务价值最高,其次是草地生态系统,荒漠生态系统服务价值最低;(2)19952015年不同区域单位面积生态系统服务价值具有显著空间差异,山区、高原区远大于丘陵、平原区;不同区域生态系统服务总价值呈现出山区>平原区>高原区>丘陵区的特点;(3)各类生态系统其服务价值及不同区域生态系统服务价值均与生态系统服务总价值基本呈现出一致的变化规律:19952000年趋于下降,20002010年趋于上升;20102015年基本呈下降趋势;整体上,19952015年生态系统服务价值总量下降了19.75%;(4)19952015年同一项生态系统服务价值在不同时期所占比重趋于稳定;同一时期各项生态系统服务价值所占比重呈现出显著差异性,11种生态服务类型中,气候调节价值对生态系统服务总价值的贡献最大,其次是水文调节价值,水资源供给价值所占比例最小;(5)生态系统服务价值对生态价值系数缺乏弹性,研究结果可信。该区域在今后生态建设与保护及区域国土空间规划等工作中应继续坚持可持续发展道路,谋求经济与生态环境的高度协调发展。
英文摘要	The series remote sensing images of Landsat of five periods in 1995,2000,2005,2010 and 2015 were used as primary data source.The ecosystem service value of Longmenshan region was calculated based on the improved equivalent factor method,and the sensitivity index was analyzed.The results showed that:(1)from 1995 to 2015,the value of forest ecosystem services was the highest among the ecosystems in Longmenshan region,followed by grassland ecosystem,and the value of desert ecosystem services was the lowest;(2)the ecosystem service value of per unit area in different areas showed spatial heterogeneity during 1995 to 2015;the per unit area ecosystem service values in the mountain areas and the plateau areas were much higher than those in plain and hilly areas;and the total ecosystem service values in different areas decreased in the order:the mountain area>the plain area>the plateau area>the hilly area;(3)both the service values of each type ecosystems and the total ecosystem service values of different regions showed the consistent change rule with the total ecosystem services value:they all declined from 1995 to 2000 and increased from 2000 to 2010,and declined on the whole from 2010 to 2015;overall,the total ecosystem service value decreased by 19.75% from 1995 to 2015;(4)from 1995 to 2015,in different period,the proportion of the value of the same ecosystem service in the total ecosystem service value was stable;however,in the same period,the proportion of the value of different ecosystem service in the total ecosystem service value showed the significant difference;among the 11 types of ecosystem services values,the value of climate regulation contributed to the total ecosystem service value mostly,followed by the value of hydrology regulation,and the value of water supply accounted for the least;(5)the ecosystem service value was inelastic to ecosystem value coefficient,so the research results were credible.During ecological construction and protection,regional territorial space planning and other works in the region in the future,the path of sustainable development should be adhered so as to achieve a highly coordinated development between economy and ecological environment.
