- Abstract:
-
The Shapotou District of the Ningxia Autonomous Region was selected an example, and remote sensing images in 2000, 2007 and 2013 were selected as data sources, land use dynamic degree, GIS spatial analysis method and the Chinese land ecosystem service value estimation method were used to study the change of land use and the change of ecosystem service value. The results showed that the land use change was significant in Shapotou District from 2000 to 2013, and the areas of cultivated land and unused land decreased by 39 951.90 hm2 and 241 289.24 hm2, respectively; the area of other land use types increased year by year, and the area of grassland increased by 10.58%; during the study period, the value of ecosystem services in Shapotou District increased, and the increase of grassland and forest land area played the leading role. From the perspective of the ecosystem service value of Shapotou District, the ecosystem services of grassland and woodland were the main components of the value of ecosystem services. The proportion of soil formation and protection, waste treatment and biodiversity conservation in the value of individual ecological function services accounted for the most value of ecosystem services in the study area, and the sum of the three accounted more than 55% of the total value of the ecosystem services. The sensitivity index of the ecosystem service value of each land use type was less than 1, which indicates that the ecosystem service value of Shapotou District is not flexible to the value index of ecological service function, and the results are credible.
