Spatio-temporal Variation in the Value of Ecosystem Services and Its Response to LUCC in Ebinur Lake Basin
Based on remote sensing and GIS technology,using China inland eco-system service value as gauge,combined with landscape types of Ebinur watershed,the changes of ecosystem services value during 2001-2009 were analyzed,the reaction of the inland lake basin in arid zone ecosystem services change on land use/cover change(LUCC) was discussed.The results showed that:the change of land use type is obvious in Ebinur watershed,and the integrated land use dynamic degree is 6.84,among which the most obvious change is plowland,desert,forest land from a single dynamic,but the grassland and water change slightly.The entirety change is not so much in ecosystem services value in Ebinar watershed,and the total value changes from 39.57 billion yuan to 39.014 billion yuan during the research period,and the result is that the grassland and water area is declining,but the increasing of plowland,brush and forest land makes up the partial lose of total value ; The spatial difference of ecosystem service value is remarkable in the research area,and the ecosystem service value change most frequently area is located in the desert of the middle part of the watershed and the oasis ecotone,in which the area of desert is keeping expanding,and the ecosystem service value declines so obvious,meanwhile this trend is spreading to oasis.The achievement of the study provide the basis for national ecological reserve land science management,protection and development.
