图们江跨国界地区生态系统服务价值研究

Research of ecosystem services value in the transboundary area of Tumen River

以2000年和2010年遥感影像解译数据为基础,对生态系统服务价值因子表及单位面积旱田食物生产公式进行区域修订,比较分析了图们江跨国界地区(中国、朝鲜、俄罗斯)10年土地利用及生态系统服务价值变化.结果表明:中国一侧的林地、水田面积有所减少,草地、旱田、水体、未利用地面积有所增加,生态系统服务价值(ESV)下降了5.26%;朝鲜一侧的各生态系统面积都有不同程度的增加,ESV上升了21.8%;俄罗斯一侧的森林、未利用地面积有所增加,其他生态系统面积则减少,ESV上升率为5.66%.

Based on the data of image in the year of 2000and 2010,we adjusted the ecosystem services value（ESV）factors and the formula of dryfarm food producing,then compared and analyzed land use change and ecosystem services value change in 10years in the transboundary of Tumen River（China,North Korea,Russia）.The results showed that：in China,the forest area and paddy field area had increased,on the contrary,the areas of grassland,dryfarm,water area and unused land had decreased,besides,the ESV dropped by5.26%;the every ecosystem area in North Korea had different increases where the ESV increased by 21.8%;and in Russia,forest and unused land area had increased,but the remind ecosystem area had decreased,the ESV increasing rate is 5.66%.
