摘要: 利用遥感技术,结合生态学方法,在对生态参数遥感测量的基础上,计算了中国陆地生态系统2000年的生态服务价值.结果表明,中国陆地生态系统2000年所产生的生态服务价值为9.17×1012元,总体空间分布由东向西递减、由中部向东北和南部递增,与植被的地带性分布梯度基本一致;森林的平均单位面积价值最高,为18789元·hm-2,占总生态服务价值的40.80%;其次是灌丛(13789元·hm-2)和耕地(13054元·hm-2),分别占总生态服务价值的10.79%和24.23%.从生态系统服务功能来看,气体调节价值的贡献率最大,占总价值的45.16%;其次是水土保持价值(28.83%)和涵养水源价值(14.44%);有机物质生产和营养物质循环的价值最小,其贡献率为11.57%.生态遥感测量方法克服了传统生态统计方法以点代面的缺点,计算结果能更加客观地反映生态系统服务价值及其空间分布,但该方法本身也存在一些不确定性,对生态系统各项服务功能及其价值的评估只是保守和粗略的估计,有待于深入研究.

Abstract: With the measurement of net primary productivity and vegetation coverage fraction based on remote sensing data,the terrestrial ecosystem service value of China in 2000 was quantitatively estimated as 9.17?1012 yuan (RMB).The spatial distribution of the ecological service value showed a decreasing trend from southeast China to northwest China,which was consistent with the regional distribution of vegetation types.The service value varied with different vegetations,e.g.,forests had the highest service value of 18 789 yuan穐m-2,accounting for (40.80%) of the total terrestrial ecosystem service value,and bushes and farmlands had a higher service value of 13 789 yuan穐m-2 and 13 054 yuan穐m-2,which was 10.79% and 24.23% of total value,respectively.The service value was also varied with different ecosystem functions,i.e.,gas regulation contributed the highest value of 45.16% to the total service value,and the contribution of soil conservation and water conservation was (28.83%) and 14.44%,respectively.The integrated approach coupling ecology and remote sensing data provided a new method to measure the ecological service value,which could estimate the value objectively and spatial-explicitly.However,some uncertainties still existed in this approach,which should be improved in the future studies.
