中文摘要	分析了20002010年我囯水源涵养型、水土保持型、防风固沙型、生物多样性维护型重点生态功能区的生态系统结构、质量与核心服务的变化.结果表明:近11年来,水源涵养型重点生态功能区的森林、草地面积减少,水体与湿的面积增加,森林、草地、湿地生态系统水源涵养总量增加了2.9%,该类区域需要遏制森林、草地的减少趋势.水土保持型重点生态功能区的农田面积减少,而森林、草地、水体与湿地的面积增加,土壤侵蚀总量减少了28.2%,生态系统土壤保持总量增加了38.1%.防风固沙型重点生态功能区的农田、森林面积增加,草地、水体与湿地的面积减少,单位面积土壤风蚀量下降,单位面积防风固沙服务量有所提升,该类区域多位于干旱半干旱区,需要减少农田面积,优先保护原有生态系统.生物多样性维护型重点生态功能区的草地、荒漠面积减少,其他类型的面积有所增加,人类扰动呈现微弱的上升趋势,该类区域需要减少人类干扰.重点生态功能区应该针对核心服务和保护目标,分类分区开展生态系统保护、改善及其效果的定量综合评估.
英文摘要	In this paper,the dynamics of ecosystem macrostructure,qualities and core services during 2000 and 2010 were analyzed for the key ecological function zones of China, which were classified into four types of water conservation,soil conservation, wind prevention and sand fixation,and biodiversity maintenance. In the water conservation ecological function zones,the areas of forest and grassland ecosystems were decreased whereas water bodies and wetland were increased in the past 11 years, and the water conservation volume of forest,grassland and wetland ecosystems increased by 2.9%. This region needs to reverse the decreasing trends of forest and grassland ecosystems. In the soil conservation ecological function zones, the area of farmland ecosystem was decreased, and the areas of forest, grassland, water bodies and wetland ecosystems were increased. The total amount of the soil erosion was reduced by 28.2%, however, the soil conservation amount of ecosystems increased by 38.1%. In the wind prevention and sand fixation ecological function zones, the areas of grassland,water bodies and wetland ecosystems were decreased, but forest and farmland ecosystems were increased. The unit amount of the soil wind erosion was reduced and the sand fixation amount of ecosystems increased lightly. In this kind of region that is located in arid and semiarid areas, ecological conservation needs to reduce farmland area and give priority to the protection of the original ecological system. In the biodiversity maintenance ecological function zones, the areas of grassland and desert ecosystems were decreased and other types were increased. The human disturbances showed a weakly upward trend and needs to be reduced. The key ecological function zones should be aimed at the core services and the protecting objects,to assess quantitatively on the effectiveness of ecosystem conservation and improvement.
