哈尔滨都市圈生态系统服务价值时空演变特征研究

Research on the Spatiotemporal Evolution Characteristics of Ecosystem Service Value in the Harbin Metropolitan Area

摘要: 哈尔滨都市圈作为东北振兴的核心引擎和对俄开放的门户，近年来随着城市化进程加速，哈尔滨都市圈生态系统服务价值的时空变化特征比较明显。因此，本文以哈尔滨都市圈为研究对象，基于2005~2020年土地利用数据，采用土地利用动态度和土地利用转移矩阵的方法，结合生态系统服务价值测算模型，分析生态系统服务价值时空演变特征及驱动机制。结果表明：(1) 2005~2020年，哈尔滨都市圈的生态系统服务价值先减少后增加，总体呈现正向增长。其中，草地和水域面积的扩张是推动ESV增加的主要原因，而耕地与林地的缩减则成为制约ESV增长的关键因素。(2) 空间分布上，呈现中高西低的格局特征。松花江流域及研究区北部呈现ESV高值集聚特征。

Abstract: As the core engine of Northeast China’s revitalization and the gateway to Russia, the Harbin Metropolitan Area has seen significant spatiotemporal changes in the value of its ecosystem services in recent years, driven by accelerated urbanization. Therefore, this study takes the Harbin Metropolitan Area as its research object, utilizing land use data from 2005 to 2020. It employs methods such as land use dynamics and land use transition matrices, combined with an ecosystem service value estimation model, to analyze the spatiotemporal evolution characteristics and driving factors of ecosystem service value. The results indicate: (1) From 2005 to 2020, the ecosystem service value (ESV) of the Harbin urban agglomeration first decreased and then increased, showing an overall positive growth trend. The expansion of grassland and water area was the primary driver of ESV growth, while the reduction of farmland and forest land became the key factor constraining ESV growth. (2) Spatially, the distribution exhibited a pattern of high values in the central region and low values in the western region. The Songhua River basin and the northern part of the study area showed a concentration of high ecosystem service values.
