摘要
[目的]分析岷江流域三江汇流区土地利用与生态服务功能的变化。[方法]以乐山市中区为例,对乐山市中区2005—2014年土地利用变化与生态系统服务功能变化进行评价。[结果]林地面积年均增加量最多(769.20 hm2),而园地面积减少最多(-488.90 hm2)。生态系统服务价值缓慢增加,10年平均增加875.99万元,主要归因于林地的年均增加值(2 007.68万元)。调节服务功能年均增加最多(398.53万元),而文化服务年均增加速度最快(1.75%)。气体调节功能的年均增加量最多(173.28万元),而文化娱乐功能的年均增加率最迅速(1.75%)。[结论]在今后的岷江流域三江汇流区的土地调控中,继续增加林地面积和保护耕地,为增加生态系统服务功能奠定良好的生态基础。
[Objective] The research aimed to analyze the changes of land use and ecological service functions in Sanjiang Confluence Area of Minjiang River Basin.[Method]Taking the central district of Leshan City as an example, the change of land use and ecosystem service function in the central district of Leshan City from 2005 to 2014 were evaluated.[Result]The annual increase of forest area was the largest (769.20 hm 2), while the decrease of garden area was the largest (-488.90 hm 2).The ecosystem services value had slowly increased, with an average increase of RMB 8.759 9 million yuan in 10 years, mainly due to the annual increase of forest land value (RMB 20.076 8 million yuan).The annual growth rate of mediation services was the highest (RMB 3.985 3 million yuan), while the annual growth rate of cultural services was the fastest (1.75%).The annual increase of gas regulation function was the highest (1.732 8 million yuan), while the annual increase rate of cultural and entertainment function was the fastest (1.75%). [Conclusion] In the future land regulation and control of the Sanjiang Confluence Area in the Lancang River Basin,the forest area will be increased and the cultivated land will be protected, which will lay a good ecological foundation for increasing the service function of the ecosystem.
