摘要: 借鉴生态系统服务价值(ecosystem services value, ESV)相关评估方法,本文定量计算了浙江省普陀区生态系统服务价值当量,分析了土地利用变化造成的生态系统服务价值变动以及规划结构对生态系统服务价值的潜在影响。结果表明:2006—2012年,普陀区土地利用变化明显,主要表现在建设用地的大量增加,以及耕地和荒草地的大量减少;2012年相比2006年的生态系统服务价值增加了0.320亿元,主要是因为沿海有较大面积耕地被开发为生态系统服务价值相对更高的水域;根据2006—2020年土地利用总体规划,普陀区2020年的生态系统服务价值将下降0.991亿元,主要是因为林地、水域和滩涂沼泽等生态系统服务价值高的土地利用类型被调整为服务价值较低的建设用地;普陀区的建设用地指标已经提前突破,耕地资源量距指标要求尚有较大差距,2006—2020年土地利用总体规划已经不能适应普陀区发展,新一轮的规划修编应考虑生态系统服务价值来协调区域发展用地需求和生态保护。

Abstract: Using related methods of evaluating ecosystem service value (ESV), the ESV ofisland ecosystems in Putuo District, Zhoushan Archipelago was evaluated. The changes of ESV caused by land use change and the potential impacts of planned land use structure on ESV were analyzed. The results showed that the land use change was obvious in Putuo District from 2006 to 2012, with a substantial increase of construction land and a significant decrease of cropland and wasteland. The ESV increased by 32.0 million yuan from 2006 to 2012 due to the conversion of largearea cropland into waters, the ESV of which being higher. According to the land useplanning for the period of 2006 to 2020, the ESV in 2020 would decrease by 99.1 million yuan because land use types such as forest, water and tidal marsh with high ESV would be changed into those with relatively low ESV, such as construction land. Moreover, the construction land would be in excessive growth, while the cropland area could not meet the planning requirement. Therefore, the land use planning in 2006-2020 would be unable to meet the development ofPutuo District. Further adjustment should take the ESV into account to balance land userequirement and ecological protection of regional development.
