摘要
分析生态系统服务之间多变复杂的相互作用,为哈尔滨市多尺度区域规划与生态系统管理制定策略提供参考.计算 2010-2020 年 3 个时期的生态系统服务,并在网格、乡镇、区县尺度上计算生态系统服务相关性、空间相关性,最后计算 3 个尺度生态系统服务簇.结果表明:1)2010-2020 年 3 个时段生态系统空间格局基本稳定,其中 2020 年林地固碳最高值由 7.43 t下降至 5.13 t,产水量与降水量密切相关,2015 年低至483.9 mm.2)生态系统服务权衡协同关系随时间、尺度改变,6对生态系统服务为协同效应,其中5对随着尺度增大协同效应增强,6对生态系统服务呈现权衡效应,权衡效应在乡镇尺度发生变化.3)3 个尺度生态系统服务簇有差异,而生态综合簇、林地协同簇在 3 个尺度相似,反映不同尺度区域特征,可为多尺度管理提供依据.
Abstract
This paper analyzes the variable and complex interactions between ecosystem services,and provides a reference for the formulation of multi-scale regional planning and ecosystem manage-ment strategies in Harbin.The ecosystem services for three periods from 2010 to 2020 were calculat-ed,and the ecosystem service correlation and spatial correlation were calculated at the grid,town-ship,district and county scales,and finally the ecosystem service clusters at the three scales were calculated.The results showed that:1)The spatial pattern of the ecosystem was basically stable in the three periods from 2010 to 2020.The maximum value of carbon sequestration in forest land de-creased from 7.43 t to 5.13 t in 2020,and the water yield was closely related to precipitation,which was as low as 483.9 mm in 2015.2)The trade-off synergies of ecosystem services changed with time and scale.6 pairs of ecosystem services showed synergistic effects,five of which showed synergistic effects with the increase of scale.Another six pairs of ecosystem services showed trade-off effects,and the trade-off effects changed at the township scale.3)There were differences in e-cosystem service clusters at the three scales,while the ecological comprehensive clusters and wood-land synergy clusters were similar at the three scales,reflecting the regional characteristics of differ-ent scales,which could provide a basis for multi-scale management.
