- Abstract:
-
In view of the problem that the loss of ecosystem service cannot be reduced by changing the spatial distribution of urban land expansion, because the study on the influence of urban land expansion on ecosystem services lacks of spatial factors(slope, elevation and echelon), we selected Wuhan as a case example to calculate the value of important ecosystem services and the temporal and spatial variation characteristics of urban land expansion, and explore the spatial and temporal influence feature of urban land expansion on ecosystem services. The results were as follows. The regions with high ecosystem service value(ESV)or low ESV staggered in the central part of Wuhan, which was most affected by urban land expansion, and the area with extremely low value of ESV was expanding and gradually spreading to the western and eastern regions. In the past 25 years, the area of urban land expansion had continued to increase. In the period 1990—2005, the urban land expansion rate was relatively stable. In the period 2005—2015, the urban land expansion rate increased rapidly. It can be seen that the urban expansion area has played a major role in the ecosystem service. Urban expansion category has a secondary impact. The degree of expansion elevation has a greater impact, and the degree of expansion has a lower degree of influence. The degree of expansion elevation is greater, and the degree of expansion distance is less affected. The expansion slope only affects food production and soil conservation. In the future expansion of urban land use in Wuhan, the scope of the central urban area should be controlled and new satellite cities should be built in the area far from the city center.
