- Abstract:
- In order to provide scientific data and reference basis for the assessment of the economic benefits of ecological restoration projects in the Loess Plateau region of northern Shaanxi, the response of the regional ecosystem service values to land use changes was profiled based on the land use change data interpreted from remote sensing images, using the per unit area value method. The results showed that:(1)from 1997 to 2018, the changes in land use patterns were mainly manifested by the transformation of farmland to forest and grassland, and unused to grassland, forest and farmland; these transformations simultaneously contributed to an increase of 35.756 billion yuan or 33.28% in the ecosystem service value in the study area, with the largest increment in Yulin and the smallest in Tongchuan, respectively; all service value was increasing, except for the value of food production function, which was decreasing; the value of regulating services was increasing the most, and the value of cultural services was increasing the most;(2)the increase in ecosystem service value in 32.93% of the study area mainly concentrated in the areas of returning farmland to forest and wind and sand control in the Loess Plateau area; the conversion of farmland to forest and grassland was the main driver of the increase in value, prompting an increase in service value of 36.364 billion yuan, accounting for 95.68% of the total increase; the conversion of unused land was another contributing factor to the increase in service value, prompting an increase in value volume of 1.642 billion yuan, accounting for 4.32%; the decrease of ecosystem service value in 5.92% of the study area concentrated in the western wind and sand area and the southern residual loess area; the conversion of forest and grassland to farmland due to the construction of large centralized farms contributed to the loss of service value of 7.017 billion yuan, accounting for 93.08% of the total loss;(3)the ecosystem service value was increasing in 43.24% of the areas under the jurisdiction of Yulin, 23.37% in Yan'an, and only 11.51% in Tongchuan;(4)among the different feature types, the ecosystem service value of forest increased the most, followed by grassland; the service value of farmland ecosystems decreased the most. The above monitoring results indicate that the implementation of the ecological restoration project in the study area has led to changes in its land use structure and subsequently prompted a significant increase in ecological service values, and the ecological restoration project has achieved certain economic benefits.
