- Abstract:
-
Yanqing District is one of the ecological conservation areas in Beijing, and provids ecosystem goods and services for Beijing and surrounding areas continuously, which has important ecological value. In this paper, multiple methods such as market value, shadow engineering, replacement cost, travel cost, willingness to pay were used to value the ecosystem product supplies, regulating and cultural services of Yanqing District in 2016, which includes 17 services. And value mapping was conducted based on the value per unit area of different towns and villages and different types of ecosystem. The results showed that:(1)gross ecosystem product(GEP)of Yanqing District in 2016 was 33.563 billion Yuan, among which the regulating service value was the highest, accounting for 91.4% of the GEP; value of product supplies and cultural service were relatively low, accounting for 3.8%, 4.8% respectively;(2)from the aspect of different ecosystem services, value of life maintenance and habitat protection was the highest, which was 14.6 billion Yuan, accounting for 43.5% of the GEP, followed by climate regulation, soil conservation, carbon sequestration and oxygen release, water conservation, accounting for 15.8%, 12.1%, 10.0%,5.4%, respectively; the sum of four service values mentioned above accounted for 81.4% of the GEP in Yanqing;(3)from the aspect of different ecosystem types, GEP decreased in the order: forest>wetland>farmland>grassland>city> bare land; the value of forest ecosystem was the highest, which was 26.879 billion Yuan, accounting for 80.1% of the GEP; wetland and farmland accounted for 10.9% and 7.8%, respectively;(4)value per unit area decreased in the sequence: wetland>forest>farmland>grassland>bare land>city, the value of wetland per unit area was the highest, which was 118 million Yuan/km2, and was 5.9 times of that of forest and 16.8 times of that of farmland;(5)the supply and demand of GEP did not match in space, which means that plain areas with relatively concentrated population were the main demand areas for ecosystem services, while the mountainous areas were main supply areas of GEP.
