摘要: 提出了一种基于第一次全国地理国情普查地表覆盖等多源遥感信息的全国陆地生态系统服务价值计算方法,分析了各遥感信息特征及大数据产生过程,结合中国陆地生态系统分类标准及单位面积生态系统服务价值当量因子,设计了数据计算算法,并以浙江省丽水市为研究区进行了验证。结果显示:研究区2015年生态系统服务价值总量为968.20亿元,人均3.70万元;各覆盖类型生态服务价值总量呈现森林 > 水域 > 草地 > 农田 > 荒漠的特点。研究表明:以第一次全国地理国情普查地表覆盖栅格化结果等多源遥感信息为基础数据源,可计算得出高精度的量化及空间化生态系统服务价值成果;设计的数据计算算法解决了多源遥感信息一体化I/O及计算负载等问题,运行效率和性能满足计算需求。

Abstract: A calculating method of national land's ecosystem service values is proposed,which is based on multi-source of remote sensing information,mainly the land cover product obtained in the project of the first Geographic National Conditions Investigation.It analyses the data characters and the big data's engendering process.Combining the classification standard of terrestrial ecosystem in China and the equivalent value factor per unit ecosystem area,the big data calculating algorithm is designed.And Lishui city,Zhejiang province is selected as the study area for validating the calculating method.The results show that the total value of ecosystem services in Lishui city in 2015 is 9.682×1010 Y,and the per capita is 3.70×104 Y.Specially,forest supplies the most ecosystem service values,followed by water,grassland,farmland,and desert.The research shows that on the basis of multi-source of remote sensing information mainly the land cover product obtained in the project of the first Geographic National Conditions Investigation,high-precision quantification and spatialization ecosystem service values can be calculated and achieved.The big data calculating algorithm has solved the problems of multi-source remote sensing information integration I/O and calculating load in the processing;and the operational efficiency and performance can meet the calculating needs.

Key words: ecosystem service values, remote sensing information, geographic national conditions investigation, land cover, big data, calculation
