- Abstract:
- To assess the value of the ecosystem service in Huailai County from the terrain gradient, we used the land dynamics and DEM data of 2003 and 2013 to quantitatively analyze the spatial distribution and characteristics of ecosystem services in Huailai County. The county susceptibility index was analyzed. The results showed that the total value of ecosystem service in Huailai County had increased by 38 million yuan between 2003 and 2013, and the values of ecosystem services in the garden and woodland had increased by 70.776 3 million yuan, 43.313 6 million yuan, respectively, and the the values of ecosystem services of water bodies and cultivated lands decreased by 41.908 4 million yuan, 32.927 4 million yuan, respectively; the value of ecosystem services was mainly in the range of 600~900 m in the gradient; the value of water conservation, waste treatment and food production ecosystem services significantly decreased by 24.513 million yuan due to the decrease of water area and cultivated land area. In the range of 15°~25°, the sensitivity index of Huailai County was less than 1, which indicates that the ecosystem value of Huailai County was inelastic to the ecological value coefficient. The result calculated by using the coefficient of the regional ecological value was credible.
