Study on the response of ecosystem services to land use

Abstract

In recent years, the urbanization process in counties has been accelerated due to the support of national policies. The depth and breadth of land use changes in counties have been strengthened, and the value of ecosystem services has been significantly degraded. In order to realize the sustainable development of county ecological environment, it is especially urgent to grasp the impact of different land use types in the county on the value of ecosystem services within a certain period of time. Based on the interpretation of remote sensing satellite images to obtain county land use classification data, the changes in the value of ecosystem services in Nanping City between 1995 and 2015 were explored in depth. The results of the study showed that the total value of ecosystem services in each region changed significantly in different time periods, among which, in 1995, the total value of ecosystem service types in Jian'ou City was the highest. In 2015, the value of ecosystem services in Songxi County decreased the most, amounting to 13.98 billion yuan, while other regions had different degrees of increase. Each regional service type has the highest value of functions such as soil formation and protection, water conservation, gas regulation and biodiversity conservation, while all the food production functions have the lowest value.
