| 摘 要： | 近几十年,内蒙古地区实施了诸多生态修复与保育工程。为了评估这些工程的实施成效,本文以土地利用/覆被变化(LUCC)为切入点,借助价值存量、价值增量、价值空间强度等参量,在全区和盟市尺度上,估算并分析了内蒙古地区陆地生态系统服务功能价值变化的时空特征及驱动因素。研究结果表明：(1)2000年以来,全区价值存量小幅度增加了0.24%,但价值增量的减少速度加快了32.9%,且中东部的变化大于西部;(2)在经济发展和人口增长的双重压力下,中东部平原耕作区、森林保育区深受国家宏观政策的影响,2000年后生态系统服务功能价值存量分别增加了4.52%、4.23%,价值增量分别增加了5.91亿元、8.88亿元;中西部山区草原荒漠化治理区受制于降水不显著的波动减少态势,2000年后生态系统服务功能价值存量增加了3.51%,但价值增量减少了4.22亿元;(3)2000年以来,中东部地区人类活动正向胁迫的影响力,由前期的45.8%增强到后期的76%,但中西部地区仍然面临着艰巨的生态治理压力。研究结果为科学合理划分生态功能区、规划实施生态修复与保育工程、建立生态补偿机制提供了参照。

| Abstract: | In the past few decades, a series of ecological restoration and protection projects had been implemented in the Inner Mongolia region. However, which extent these projects met the satisfaction?In this paper, from the perspective of land use/land cover data and DPSIR conceptual framework, we systematically describe spatial and temporal changes of ecosystem services values and analyze driving factors of these changes from both the regional and the prefecture-level scale, adopting the parameters of the stock value, intensity of the stock value and the incremental value. The results show that:(1) Since 2000, the whole region's stock value had increased by only 0.24%, but the decreasing rate of the cumulative positive and negative incremental values had promoted by 32.9%. There are more changes occurred in the eastern area than in the western area; (2) Since 2000, after the "Grain for Green" policy was carried out, the stock values of ecosystem services in the plain cultivation areas and forests conservation areas had increased by 4.52% and 4.23% respectively, yet the incremental values had increased by 0.59 billion and 0.89 billion respectively. All the changes was constrained by climate change, population growth and a series of political and economic macro-policies; (3) Since 2000, the stock value had increased by 3.51%, while the incremental value still decreased by 0.42 billion in the highland steppe areas, which was constrained by the precipitation fluctuations and population growth factors; (4) Since 2000, the positive influences of human activities in central and eastern areas gradually increased from 45.8% to 76%; however, under the traditional way of economic development, the ecological protection in the midwest areas still faced great difficulties and pressures. The result of our study provides a scientific reference for dividing eco-zone and constructing eco-restoration, and it could be further utilized in establishing a suitable ecological compensation mechanism. |
