摘要:
为阐明九寨沟世界自然遗产地生态系统服务的时空变化动态，明确在土地利用变化与气候变化下该地生态系统服务变化过程，针对植被净初级生产力(NPP)、水源涵养、土壤保持三种区域最主要的生态系统服务功能进行时空动态评估，并基于情景构建，开展不同变化情景下的九寨沟世界自然遗产地生态系统服务变化研究。结果表明：（1）3种生态系统服务供给量在1990-2015年间呈现下降趋势，其中NPP降幅最大，由1990年的13.774×105 t下降至2015年的10.934×105 t，降幅为21.34%。（2）3类情景下，生态系统服务供给量及空间分布均存在较大差异。在生态系统服务供给总量上整体呈现土地利用变化情景（情景2）>真实变化情景（情景1）>气候变化情景（情景3）的变化趋势，在情景2下，NPP增长0.29×103 t，水源涵养、土壤保持分别减少0.008×108 m3、0.002×106 t，变化幅度均小于情景1、情景3。通过不同情景的比较，本研究表明仅由土地利用变化导致的九寨沟生态系统服务供给总量变化较其他两类情景更小，且其供给总量也最大。同时，暖干化的气候变化趋势对九寨沟生态系统服务的供给产生了显著的负面效应，也在一定程度上影响了生态系统服务变化的空间格局，尤其是对水源涵养功能的影响较为显著。
Abstract:
This study was conducted to clarify the spatiotemporal dynamics of the supply of ecosystem services in Jiuzhaigou World Natural Heritage site and to reveal the changing process of ecosystem services driven by the land use change and climate change. Based on the uation of the three main ecosystem services, Net primary productivity(NPP), Water conservation, Soil conservation, this study constructed three types of change scenarios to reveal the change progress of ecosystem services in Jiuzhaigou World Natural Heritage site. The results showed that:(1) The supply of three ecosystem services showed a downward trend from 1990 to 2015, in which NPP decreased the most, from 13.774×105 t in 1990 to 10.934×105 t in 2015, with a decrease rate of 21.34%. (2) there were significant differences in the total supply and composition structure of the three scenarios. Among them, the overall trend of scenario 2 > scenario 1 > scenario 3 on the level of service supply. Under scenario2, NPP increased by 0.29 ×103 t, supply of water conservation and soil conservation decreased by 0.008×108 m3 and 0.002×106 t respectively, and the change range was smaller than that in scenario 1 and scenario 3. Through the comparison of different scenarios, this study showed that the change of the total supply of ecosystem services caused by land use change was smaller than that of the other two scenarios. At the same time, the climate change trend of warming and drying had a significant negative effect on the supply of ecosystem services in Jiuzhaigou, and also affected the spatial pattern of ecosystem services change to a certain extent, especially the water conservation function.
