基于InVEST模型的山东省生态系统服务时空演变

Spatial and Temporal Evolution of Ecosystem Services in Shandong Province Based on InVEST Model

  • 摘要: 分析山东省生态系统服务功能时空分布驱动因素,查找当地生态系统服务受到抑制的主要因素,提高森林、耕地和水体等生态系统生产力水平。基于InVEST模型,以山东省为研究区域,评估2010年、2015年、2020年水源涵养、土壤保持和生境质量3项生态系统服务物质量及3项生态系统服务功能间的综合分区。结果表明:(1)土地利用转化以草地和耕地,耕地、林地、水体和城镇建设用地之间的相互转化为主。(2)水源涵养量和土壤保持量呈现先减少后增加的趋势,生境质量指数逐年降低。(3)山东省生态系统服务功能分区呈现带状分布,大致呈现东北-西南走向,重要性等级也呈现逐步降低的趋势。显示出山东省整体的城镇化速度在明显加快,土地利用转化频率较快,人地矛盾突出正在加剧。

     

    Abstract: The driving factors of spatial and temporal distribution of ecosystem services in Shandong province were analyzed, and the main factors of local ecosystem services being inhibited were found, so as to improve the productivity of forest, cultivated land and water system. Based on InVEST model, taking Shandong province as the research area, the quality of three ecosystem services, including water conservation, soil conservation and habitat quality, and the hierarchical function zone among three ecosystem services in 2010, 2015 and 2020 were evaluated. The results showed that: (1) The conversion of land use was mainly between grassland and cultivated land, and between cultivated land, forest land, water body and urban construction land. (2) Water conservation and soil conservation showed a trend of first decreasing and then increasing, and the habitat quality index decreased year by year. (3) The distribution of ecosystem services in Shandong province showed a zonal pattern, with a northeast-southwest trend, and the importance level of ecosystem services decreased gradually. The results indicated that the overall urbanization speed of Shandong province was obviously accelerating, the frequency of land use transformation was relatively fast, and the contradiction between man and land was intensifying.n speed of Shandong province was obviously accelerating, the frequency of land use transformation was relatively fast, and the contradiction between man and land was intensifying.n speed of Shandong province was obviously accelerating, the frequency of land use transformation was relatively fast, and the contradiction between man and land was intensifying.
