为明确区域生态系统服务供给和需求的匹配关系,实现区域生态和社会经济的可持续发展,基于InVEST模型,量化太行山区保定段8个县域2005-2020年粮食供给和碳固定服务的供给量和需求量,对供需关系的时空特征进行研究,并为保定太行山区的生态系统服务管理提出合理建议.研究结果显示:(1)2005-2020年保定太行山区的粮食供给服务供给量呈现波动上升的趋势,需求量和供需比呈现持续上升的趋势;产水服务供给量和需求量呈现逐步上升的趋势,而供需比呈先上升后下降的趋势;碳固定服务供给量呈现先下降后上升的趋势,需求量呈现持续增长的趋势,供需比呈先上升后下降的趋势.(2)2005-2020年保定太行山区的粮食供给—产水—碳固定服务和3种生态系统服务的供需比均呈现"西北高,东南低"的分布特征.(3)2005-2020年保定太行山区的3种生态系统服务均以高供给低需求的供需特征为主,粮食供给—产水—碳固定服务的供需以供给大于需求为主.研究结果有助于了解保定太行山区的生态系统服务供需均衡匹配状况,并指导生态系统的管理和规划.
Temporal and spatial evolution of ecosystem services in Taihang Mountain Area of Baoding under the relationship between supply and demand
In order to clarify the matching relationship between supply and demand of regional ecosystem services and realize the sustainable development of regional ecology and social e-conomy,this paper quantified the supply and demand of grain supply and carbon fixation services in eight counties in Baoding section of Taihang Mountain Area from 2005 to 2020 based on InVEST model,studied the temporal and spatial characteristics of the relationship between supply and demand,and put forward reasonable suggestions for ecosystem service management in Taihang Mountain Area of Baoding.The research results showed that:(1)From 2005 to 2020,the supply of grain supply services in Taihang Mountain Area of Baoding showed a fluctuating upward trend,and both the demand and the ratio of supply and demand showed a continuous upward trend;The supply and demand of water production services were gradually increasing,while the ratio of supply and demand was first increasing and then decreasing.The supply of carbon fixed services first decreased and then increased,the de-mand continued to increase,and the ratio of supply and demand first increased and then de-creased.(2)From 2005 to 2020,the supply-demand ratio of grain supply-water production-carbon fixation service and three ecosystem services in Taihang Mountain Area of Baoding showed the distribution characteristics of"high in northwest and low in southeast".(3)From 2005 to 2020,the supply and demand characteristics of the three ecosystem services in Taihang Mountain Area of Baoding were mainly high supply and low demand,the supply and demand of grain supply-water production-carbon fixed service were mainly supply exceeding demand.The research results could provide scientific information for decision makers to un-derstand the balanced matching of supply and demand of ecosystem services in Taihang Mountain Area of Baoding,and guide the management and planning of ecosystem.
