    云南省建水县不同石漠化治理模式下碳储量功能评估

    Evaluation on carbon storage function under different rocky desertification control models in Jianshui County of Yunnan Province, southwestern China

    • 摘要:
      目的石漠化综合治理引起的土地利用变化改变了土壤呼吸条件和地表植被,进而对生态系统的碳储量功能产生影响。本文为揭示区域不同发展模式下石漠化综合治理对碳储量功能的影响。
      方法本文以云南建水县为案例,基于Dyna-CLUE和InVEST模型,以2015年为基期,模拟和预测了县域未来10年3种发展情景(快速发展、石漠化治理、规划发展)下土地利用变化对碳储量影响。
      结果(1) 石漠化治理情景下,相比2015年,2025年乔木林、建设用地、园地、水域面积均有所增加;而未利用地、耕地、草地和灌木面积有所减少。快速发展情景下,相比于2015年,耕地、园地、建设用地、乔木林和水域的面积有所增加。未利用地、灌木和草地面积有所减少。规划发展情景下,相比2015年,耕地、园地、草地、建设用地、灌木和水域面积有所增加。未利用地和乔木林面积有所减少。(2)2025年,石漠化治理情景下建水县的碳储量为318.72×105 t,相比于2015年,增加23.94×105 t,该情景为研究区提升了最多的碳储存量;快速发展情景延续之前趋势,碳储量总量为301.07×105 t,相比于2015年增加了6.29×105 t;规划发展情景下,碳储量总量为284.89×105 t,相比于2015年损失了9.89×105 t。
      结论研究反映了不同石漠化综合治理发展模式对土地利用格局及其岩溶生态系统碳储服务的影响,可为政府管理人员区域发展模式的确定,和利益相关者实施石漠化治理策略提供参考。

       

      Abstract:
      ObjectiveThe change of land use resulted from comprehensive rocky desertification control model has caused changes of soil respiration and vegetation on land surface, which will further affect the carbon storage function of ecosystem. This paper aims to reveal the impact of comprehensive rocky desertification control models on carbon storage function under different developing models.
      Methodthis paper takes Jianshui County of Yunnan Province, southwestern China as a case to simulate and predict the impacts of land use change on carbon storage under three developing scenarios (rapid development, rocky desertification control and planning development)in the next 10 years, which was carried out by InVEST combined with Dyna-CLUE models, taking year 2015 as base period.
      ResultThe results showed that: (1)under the rocky desertification control scenario, the area of arbor forest, land used for building, orchard and water area in 2025 all increased to some extent compared with 2015; while the area of unused land, farmland, grassland and shrub land all decreased. Under the rapid development scenario, compared with year 2015, the area of farmland, orchard, land used for building, arbor forest, and water area all increased; the area of unused land, shrub land and grassland all decreased to some extent. Under the planning development scenario, compared with year 2015, the area of farmland, orchard, grassland, land used for building, shrub land, and water area all increased; while the area of unused land and arbor forest decreased somewhat. (2)In 2025, the carbon storage will be 318.72 ×105 t in Jianshui County under the scenario of rocky desertification control, increased by 23.94 ×105 t compared with 2015. This scenario provided the most carbon storage for the study area. Under rapid development scenario, the total carbon storage will be 301.07 ×105 t, increased by 6.29 ×105 t compared with 2015. While under the planning development scenario, the total carbon storage will be 284.89×105 t, which was 9.89×105 t lower than 2015.
      ConclusionThe study reflects the impact of different scenarios of comprehensive rocky desertification control on land use patterns and their carbon storage services in karst ecosystems. It can provide a reference for determination of the regional development model of government managers and implementation of the stratagem of rocky desertification control by stakeholders.
