从不同生态功能区分析生态系统服务价值有助于认识生态系统服务功能的异质性。以肃南裕固族自治县、甘州区和民勤县为例,分别计算了河西走廊南部山地、中部绿洲、北部荒漠区2002年和2009年的农田生态系统服务价值,并采用多元逐步回归模型分析了不同功能区人类活动对农田生态系统服务价值变化的影响。结果表明:河西走廊单位面积农田生态系统基本服务价值和农田生态系统服务总价值都呈北部荒漠>中部绿洲>南部山地的空间梯度分异;在研究期内,不同生态功能区农田生态系统服务总价值都呈增长趋势,其中北部荒漠区增加了1.83×108元、中部绿洲增加了0.70×108元、南部山地增加了0.13×108元;农田生态系统基本服务价值,北部荒漠区年均增加0.16×108元、中部绿洲年均增加0.11×108元、南部山地年均增加0.02×108元;使用化肥等导致农田环境污染损失的价值都表现出不同程度的增大趋势;农业耗水损失价值方面,下游荒漠区年均减少0.11×108元,而中部绿洲年均增加0.03×108元,南部山地变化较小;回归分析结果显示河西走廊农田生态系统服务价值的变化主要是由种植业结构调整引起的,不同生态功能区所受影响程度具有一定差异性。

To analyze the ecosystem service value will help us to understand the function heterogeneity of the ecosystem service function from different ecological function regions. We took Sunan county, Ganzhou district, and Minqin county, three typical areas of the Mountain-Oasis-Desert (MOD) in the Hexi Corridor as an example. We calculated the farmland ecosystem service value in different ecological function regions in 2002 and 2009 by using the method of ecological economics, and analyzed the influence factors of the change of farmland ecosystem service value by using multiple regression. The results showed that: The farmland ecosystem service value per unit area of Hexi orridor was in an order of northern desert sub-ecosystem>middle oasis sub-ecosystem>southern mountain sub-ecosystem; The farmland ecosystem service value increased in different ecological function regions during the research period, such as the northern desert sub-ecosystem increased ￥1.83×108, the middle oasis sub-ecosystem increased ￥0.70×108, and the southern mountain sub-ecosystem increased ￥0.13×108; The simple ecosystem service value increased about ￥0.16×108 per year in northern desert, increased about ￥0.11×108 per year in middle oasis and increased about ￥0.02×108 per year in southern mountain; For the use of fertilizers, the loss in the value of farmland ecosystem service increased in different ecological function regions; On the agricultural water consumption side, the loss value decreased about ￥0.11×108 per year in northern desert, increased about ￥0.03×108 per year in middle oasis, but changed smaller in south mountain; The results from regression analysis may reveal that the change of farmland ecosystem service value in Hexi Corridor mainly caused by growth in structural transformation, but the impact degree exist difference in different ecological functional areas.
