- Abstract:
-
We selected four major ecosystem services such as biodiversity conservation, soil conservation, water conservation and flood storage to evaluate the importance of ecosystem services of Fuzhou coastal areas using RS and GIS techniques. We chose the minimum cumulative resistance model to conduct urban space dividing research based on a combination of ecosystem service importance assessment models. The results indicate that: (1) the ecosystem service importance of Fuzhou coastal areas is higher, the most important areas and regional area account for 66% of the total area, and the obvious spatial of ecosystem service importance is different, and the ecosystem service importance is high in the north and low in the south; (2) the total area can be divided into four parts: Suitability land for construction, restrictive land for construction, ecological conservation land and key ecological conservation land, the areas of which were 2 698.06 km2, 1 345.06 km2, 655.08 km2 and 459.92 km2, respectively. We suggest alternative development plans with respect to the actual conditions of each area.
