| 文章基于舟山岛 2000 年、2010 年和 2020 年共 3 期土地利用数据,运用地学信息图谱方法构建了 2000—2010 年和 2010—2020 年两个时期的土地利用转移图谱,计算了海岛生态系
统服务价值的变化,得到了生态系统服务价值变化图谱。结果表明:(1)2000—2020 年,舟山岛土地利用结构以林地为主,地类变化的主要趋势为耕地、水域和湿地减少,建设用地增加。
(2)舟山土地利用转移图谱主要以耕地、湿地和水域向建设用地的转变以及耕地向林地的转变为 主。(3)2000—2020 年,舟山岛生态系统服务价值由原来的 1.812 6×109 元降低至 1.167 9×109 元, 水域、耕地和湿地转变为建设用地是生态系统服务价值降低的主要原因,围填海工程对海岛生态 系统服务价值的负面影响较大。“耕地→林地”图谱单元是最主要的生态系统服务价值增值类型, 表明舟山市的水土保持和退耕还林政策带来了正面生态效益。研究结果可以为维护海岛生态系统 安全、促进海岛经济社会可持续发展提供参考依据。 |

| Abstract: |
| Based on the land use data of Zhoushan Island in 2000,2010,and 2020,this paper used the geo- information TUPU method(spatial transition mapping)to build transition TUPU of land use at two stages(2000– 2010,2010–2020),calculated the changes of ecosystem service values(ESV),and obtained the transition TUPU of ESV.The results show that:(1)From 2000 to 2020,the land use structure of Zhoushan Island was dominated by forest land,while the areas of cultivated land,water,and wetland decreased and the area of construction land increased.(2)The transfer map of land use in Zhoushan Island was dominated by the conversion of cultivated land, water,and wetland into construction land,and the transformation of cultivated land to forest land.(3)During 2000–2020,the ESV of Zhoushan Island decreased from 1.812 6×109 yuan to 1.167 9×109 yuan.The conversion of cultivated land,water,and wetland into construction land was the main reason for the decrease in ESV,which indicated that the reclamation projects had a greater negative impact on the island’s ESV.The“cultivated land → forested land”TUPU units mainly contributed to the increase of ESV,indicating the positive ecological benefits of Zhoushan’s soil and water conservation and reforestation policies.The research results can serve as a reference for maintaining the safety of island ecosystems and promoting the sustainable economic and social development of islands. |
