| 摘 要： | 山地占中国国土面积比重高,是我国破解区域发展不平衡矛盾的焦点区域,也是生态系统服务重要供给区,长期面临着经济发展和生态保护的双重压力与挑战。研究选取我国石漠化山地、新构造运动活跃区山地和北方土石山区的典型区域黔桂岩溶山地、横断山地和太行山地为案例,以支持服务中NPP(Net Primary Productivity)、调节类服务水源涵养和供给类服务农产品供给三类生态系统服务为代表,采用线性回归、相关分析等方法探讨了1990–2015年三大山地生态系统服务权衡与协同关系的时空特征。主要结论如下:(1)三大山地农产品供给服务相对下降,NPP和水文调节等支持和调节服务提升更为显著;(2)三大山地NPP与水文调节服务存在彼此增益的协同关系,黔桂岩溶山地协同关系增强,而横断山地和太行山地变弱,且前者变弱的程度更大;三大山地NPP、水文调节服务与农产品供给服务存在此消彼长的权衡关系,其中黔桂岩溶山地NPP与农产品供给服务权衡关系变弱,而横断山地和太行山地权衡关系增强,且后者变强的程度更大;(3)三大山地生态系统服务权衡与协同关系存在显著的空间分异。

| Abstract: | Mountain area accounts for a high proportion of the land area in China,and it is the focal area to solve the contradiction of imbalanced regional development,as well as an important source of ecosystem services.Therefore,this area has been facing long-term pressure and challenges in economic development and ecological protection.In this paper,we selected a rocky desertification mountain area,an active mountain area of new tectonic movement and a typical northern earth-rock mountain area,as Qian-Gui karst Mountain area,Hengduan Mountain area and Taihang Mountain area,as examples to represent three main types of mountain areas.Three representative types of ecosystem services,including NPP(Net Primary Productivity)as a support service,water conservation as a regulation service,and agricultural produce as a supply service,were incorporated into this study.Linear regression,correlation analysis and other methods were then used to investigate the spatial-temporal characteristics of the trade-offs and synergies in each of the three kinds of mountain areas during 1990-2015 in China.The analysis yielded three main conclusions for the three mountainous areas.(1)The agricultural produce supply service decreased relatively,while the support and regulation services of NPP and hydrological regulation increased significantly.(2)There was a synergistic relationship between NPP and the hydrological regulation services in the three mountainous areas.The synergistic relation in Qian-Gui karst Mountain area became enhanced,while those in Hengduan and Taihang Mountain areas became weakened,and the former was weakened to a greater extent.There was a trade-off between NPP,the hydrological regulation service and the agricultural produce supply service among the three mountainous areas.In particular,the trade-off between NPP and the agricultural produce supply service in Qian-Gui karst Mountain area became weaker,while those in Hengduan and Taihang Mountain areas were enhanced,and the latter was enhanced to a greater degree.(3)Significant spatial differentiation was evident in the trade-offs and synergies of ecosystem services among the three mountain areas. |
