摘要:以内蒙古自治区为例，基于土地利用与生态系统服务价值（ESV）的关系，提出将生态改善效果纳入生态服务功能综合评价的分级方法，并分析生态服务功能的空间分布格局，揭示生态改善与生态系统服务价值的对应关系。结果表明：（1）2015年研究区ESV为1.87万亿元，区域整体生态环境质量水平提升；（2）研究区的生态改善具有空间分异特征，高ESV改善区仅集中于大兴安岭等高生态价值区，其余地区生态改善不明显，甚至呈恶化趋势，造成地区间差距不断扩大；（3）生态系统服务的提供程度与生态改善效果具有高关联性，依据各功能和生态改善水平可将研究区划分为北部大兴安岭核心区、中部高覆盖草原区两类高值区，以及西部沙地区、南部沿黄河地区和东部科尔沁地区三类低值区。生态管控措施应综合生态服务功能与生态改善效果的匹配程度，以达到减小区域ESV差距、促进生态环境协调发展的目的。



Abstract:Using the Inner Mongolia Autonomous Region as an example, this study proposes a classification method that integrates the effects of ecological improvement into the evaluation of ecological service functions, based on the relationship between land use and ecosystem services value (ESV), and analyzes the spatial distribution patterns of ecosystem service functions. The results showed that (1) the ESV of the study area was 1.87 trillion yuan in 2015, and overall environmental quality improved; (2) the ESV improvement in the study area was spatially differentiated. The areas of greatest improvement were concentrated in areas of high ecological value. Ecological improvement was not obvious in other areas, resulting in a widening gap in environmental quality in the region; (3) a high degree of correlation was seen between ecosystem services and the rate of ESV improvement. The study area could be categorized into two high value zones, namely Daxinganling and a high-cover grassland area, as well as three low value zones, namely the Sandland, Yellow River, and Horqin areas. Ecological management should be based on ecological service function and its relationship with ecological improvement to reduce the gap between regional ecological values and, thus, promote the coordinated development of Inner Mongolia's ecological environment.
