| 根据1980尧1995和2010年吉林省西部土地覆盖类型数据，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30年吉林省西部生态系统服务价值的时空变化进行研究。结果表明，从1980-2010年，吉林省西部生态系统服务价值由5002413万元减少至4408862 万元，变化率-11.9%；由1980年中间高四周低的格局逐渐转变为北部高南部低的格局；生态系统服务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袁高-高自相关类型呈减少趋势，而低-低自相关类型呈增加趋势，全局空间自相关指数先增加后减少；生态系统服务价值质心1980-2010年总体向东北移动了12.5 km。人为开垦活动是吉林省生态系统服务价值时空动态变化的主要驱动因素。 |

| According to the data of the land cover types from the west of the Jilin Province in 1980,1995 and 2010,using the Chinese terrestrial ecosystems unit area ecological services value as scale to make a research about spatiotemporal dynamic changes of ecosystem services value of the west of Jilin Province for nearly 30 years.The results show that the ecosystem services value of the west of Jilin Province gradually reduce from 1980 to 2010, from RMB 50024.13 million to RMB 44 088.62 million , the change rate is -11.9%; from the 1980 high in the middle surrounded by low pattern gradually transformed into a pattern of high northern southern low; spatial pattern of ecosystem services toigh -value areas by the state led to a low -value gradually transformed into a state dominated area, high - high autocorrelation type showed a trend of decreased significantly, and low - low autocorrelation type showed a trend of increase, the global spatial autocorrelation index increased first and then decreased; the centroid value of ecosystem
services moved to the northeast 12.5 km in general.Artificial reclamation activity is dynamics in spatial and temporal change of ecosystem service value of the west Jilin Province. |
