- Abstract:
- In order to reveal the impact of land use on the ecological service value and ensure the smooth implementation of ecological protection and restoration projects in the upper reaches of the Fenhe River, taking the upper reaches of the Fenhe River as the research area, based on the small watershed as the unit, and based on the remote sensing images of the region in 2006, 2011 and 2016, we evaluated the of ecosystem service values in the region with reference to the equivalent estimation method. The evolution characteristics were analyzed from the perspective of overall pattern and individual service in order to provide the scientific reference for ecological restoration project of ‘mountain, forest, field, lake and grass' and land use regulation in the upper reaches of Fenhe River. The results show that:(1)the total value of ecological services in the upper reaches of the Fenhe River in 2006, 2011 and 2016 decreased year by year, and decreased by 13.74%;(2)there is a significant spatial difference in the overall ESV distribution; the mountain ESV was high, and the township center and surrounding areas were the large-scale areas with low ESVs; the contribution rate of hydrological regulation functions in single service had always been the first;(3)there is a certain degree of spatial autocorrelation in regional ESV, and ESVs were more obvious in low-value regions; during the period, there were significant changes in the distribution of the value-added hotspots and the loss of cold hotspots; the clusters in the hotspots mainly benefited from ecological measures such as returning farmland to forestlands and grasslands, and the Three-North Shelterbelt, while the cold spot area was closely related to the local industrialization and urbanization.
