摘　　要：以小三江平原1980、2000和2010年TM影像数据为基础,构建了人类活动影响下生态系统单位面积生态价值量当表,探讨了土地利用变化及由其引起的生态系统服务价值的变化。结果表明,旱田、水田和建设用地面积呈逐年递增趋势,林地、草地和湿地面积呈逐年递减趋势,草地和湿地面积的变化率均达70%以上;研究期内生态系统服务价值总值总体呈下降趋势,2000年和2010年生态服务总价值较1980年分别减少了14.91%和22.97%;除粮食生产以外,各单项服务功能生态价值均呈逐年递减趋势。为保障生态系统和经济社会的可持续发展,小三江平原地区未来土地利用应尽可能恢复和增加林地以及湿地面积。According to the statistic land-use data in 1980, 2000 and 2010, the table about ecosystem service values per area under the influence of human activity was constructed for the small Sanjiang plain, and the variations of ecosystem service values were explored. Results showed that areas of dryland, paddy land and construction land tended to increase annually while the areas of forest, grassland and wetland tended to decrease. The change rates of grassland and wetland areas reached over 70 %. The total ecosystem services value decreased on the whole, and decreased by 14. 91% and 22. 97% in 2000 and 2010 compared with those in 1980, respectively. All of single ecosystem service values declined annually except food production. Areas of forest and wetland are suggested to be restored and increase in order to maintain the sustainable development of ecosystem and social economics in the small Sanjiang plain.
