摘要:

土地利用变化与生态系统服务价值的研究对土地资源可持续开发和利用具有极为重要的意义。本文以哈尔滨市为研究区,以土地利用的遥感影像为数据源,采用基于当量因子的生态系统服务价值综合评价分析方法和敏感性分析方法,阐释所选研究区域范围内部,不同土地利用类型的生态系统服务价值变化的表现特征。通过改良和调整哈尔滨市的不同土地利用类型对应单位面积以及生态系统的服务价值和系数表,对哈尔滨市2005—2020年的生态系统服务价值的时间性与空间性基本分布格局展开全面系统深入分析。结果表明:(1)2005—2020年,哈尔滨市的耕地总面积与建设用地总面积有较小幅度的增加,同时林地的总面积呈现出逐渐减少的变化趋势。数量变化发生幅度相对较小的土地利用类型是草地、水域和未利用地;(2)哈尔滨市的总体ESV数据测算水平呈现出逐渐下降的变化趋势。哈尔滨市的生态系统服务价值贡献来源主要在于林地、耕地和水域3种用地类型。哈尔滨市现有土地生态系统服务价值发挥状态集中展现在水源涵养层面、土壤保护层面和废物处理层面上。在针对研究区制定土地利用规划方案过程中,要重点性关注以及保护林地、耕地和水域等具备较高水平生态系统服务价值系数的土地利用类型,还要开展具备更加科学化、合理化特点的利用行为规划环节,支持助推哈尔滨市各空间区域多样化土地利用类型的可持续发展。

Abstract:

The study of land use change and ecosystem service value (ESV) is of great significance to the sustainable development and utilization of land resources. Taking Harbin as the study area, the characteristics of land use changes were analyzed by using the comprehensive evaluation and sensitivity analysis method of ecosystem service value based on equivalent factor. By improving and adjusting the unit area corresponding to different land use types and the service value and coefficient table of ecosystem in Harbin, this paper made a comprehensive, systematic and in-depth analysis on the temporal and spatial distribution pattern of ecosystem service value in Harbin from 2005 to 2020. The results showed that (1) from 2005 to 2020, the area of cropland and construction land increased slightly, while the area of forest land decreased gradually; the changes of the other three land use types were relatively small; (2) the overall ESV of Harbin showed a downward trend, forest, cropland and water area were the main contributors to the value of ecosystem services in Harbin, and the ecological service value of Harbin was mainly reflected in water conservation, soil protection and waste treatment. Therefore, when formulating the land use plan for the study area, it is necessary to focus on protecting the land use types with higher ecosystem service value coefficient, such as forest, cropland and water area, and carry out more scientific and rational planning, so as to realize the sustainable development of the land use types in each region in Harbin.

Key words: ecosystem service value, Harbin, value equivalent factor, land use change
