摘　　要：根据1950—2005年挠力河流域土地利用数据,利用中国陆地生态系统单位面积生态服务价值当量表,对近60年挠力河流域生态系统服务价值的时空变化进行研究。结果表明,自1950年至2005年,挠力河流域生态系统服务价值逐渐减少,由749.84亿元降低至308.82亿元,损失约58.82%;价值空间格局由以高价值区为主导的状态逐渐转化为以低价值区为主导的状态,且价值质心由北向南发生转移;挠力河流域生态系统服务价值的全局自相关指数逐渐减小,高-高自相关类型沿河流主干道逐渐萎缩,且呈现破碎化趋势,低-低自相关类型呈先减少后增加的"V"趋势,呈现不显著连片化趋势。人为垦殖活动是该流域生态系统服务价值时空动态变化的主要驱动因素。The term ＂ecosystem services＂ refers to products such as water and ecological processes such as the natural filtering of water which the natural environment provides to mankind in the form of changed conditions in ecosystems Ecosystem services supply important materials and natural processes necessary for human survival and these services are critical in our attempts to achieve sustainable development. Research related to the value of these dynamic ecological services provides research data and refined information to land managers who can apply research results to the rational allocation of resources. The Naoli River Basin is located in the Sanjiang Plain in Heilongjiang Province, China. It is the largest watershed in the Sanjiang Plain and is one of the most typical areas representing the natural ecosystem of the Sanjiang Plain. In the last 60 years, human activities and natural changes in the Naoli River Basin have resulted in a loss of much of the original ecosystem, caused additional serious damage to the Valley＇s ecosystems, and even impacted the natural environment of the Sanjiang Plain. We studied the temporal and spatial variation of the value of ecosystem services provided by the Naoli River Basin ecosystem during the last 60 years. This research was based on land use data and measurements of ecological services provided by Chinese terrestrial ecosystems. The spatial data on ecological services was from the Naoli River Basin and had been collected between the year of 1950 and 2005. This type of data is helpful during the analysis of spatial variability and local ecosystem characteristics, and provides a scientific basis for the protection of Sanjiang Plain＇s biodiversity and supports efforts to maintain a functioning ecosystem. The results show the value of ecosystem services provided by the Naoli River Basin ecosystem gradually declined from the year of 1950 to 2005, from RMB 74. 984 billion toRMB 30. 882 billion, a loss of about 58.82%, which implies the Basin now provides fewer products and se
