中文摘要:
      农地“非农化”过程会使区域生态系统服务功能价值发生显著变化。本研究以川西北民族地区为对象,基于该区2005和2015年遥感数据及土地利用数据,利用生态系统服务价值赋值法,研究农地“非农化”转变引起的生态服务价值变化特征。结果表明:2005-2015年,研究区农用地生态价值由1013.54×108元/a增加到1222.08×108元/a,10年间生态服务总价值上升208.54×108元。农用地结构改变是该区生态服务价值上升的最主要因素。农用地中林地和草地的生态服务价值显著大于建设用地和其他农地类型。林地面积上升使生态服务价值增加281.82×108元,草地面积锐减导致其生态价值下降73.24×108元。该时期建设用地面积上升0.06×105 hm2,上升率达46.15%,但其生态服务价值变化量仅0.34×108元/a,对区域生态服务总价值影响不大。本研究表明,区域退耕还林工程的实施,促进了林地面积的大幅增长,对维持区域生态服务功能起到了关键作用。
英文摘要:
      It is important to quantify the change of ecosystem service value in the Non-agricultural Process of agricultural land.In order to quantitatively analyze the changes of ecosystem service values caused by Non-agricultural Process,economic value of ecosystem services in the Ethnic Areas of Northwest Sichuan during 2005-2015 was estimated by form of ecosystem service values coefficients for different land use categories. The data sets of spatial-temporal land use in study area were obtained from two-period remote sensing information. The changes of ecosystem service values from 2005 to 2015 were calculated. The results indicated that the total ecosystem service value increased from 1013.54×108 yuan in 2005 to 1222.08×108 yuan in 2015. It have been increased by 208.54×108 yuan. Increase in ecosystem service value is most attributed to utilization structure of agricultural land. The ecosystem service value of forest and grassland is much larger than that of other land use types. The ecosystem service value of forest increased by 281.82×108 yuan and that of grassland decreaded by 73.24×108 yuan. The construct land area increased by 0.06×105 hm2 in this period, but its service values increased about 0.64×108 yuan only. So it indicates that the increased magnitude of ecosystem service value of construct land is much smaller than that of forest and grassland. The research shows that Grain for Green Project had some effective influence on protecting ecosystem services.
