Abstract
Ecosystem services refer to the environmental conditions and utilities provided and maintained by ecosystems, which are the basis for the survival and development of human society. The studies on ecosystem services in quantitative assessments, driving mechanisms, and correlation with human well-being, based on remote sensing, have increased in recent years. Various applications of remote sensing in ecosystem services are reported in six papers published in this Special Issue. The major research topics covered by this Special Issue include the multi-method analysis (e.g., linear regression, geographical detector, and geographically weighted regression methodology) of the normalized difference vegetation index (NDVI) to reflect ecosystem structure, the dynamic changing process of ecosystem services, and the determinants, which include a new image-analysis method based on a time series of a biophysical variable and the application of fractional vegetation cover (FVC) to analyze the spatiotemporal relationship between ecosystem structure and function and the comprehensive study on ecosystem function and service based on multi-source remote sensing data. The application of remote sensing data to ecosystem services research has the advantage of monitoring ecological structure and functions at multi-scales. Furthermore, the quantitative calculation of ecosystem services, based on remote sensing, can provide a scientific basis for enhancing land use optimization and sustainable development.
Highlights
Ecosystem services have become a hotspot of interdisciplinary research because of their integrated characterization of natural system structure and function, and the comprehensive reflection of natural and social system feedback mechanisms [1,2,3,4]
The conceptual framework developed by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) emphasizes the development of vertical series and mutual feedback research from the three dimensions of natural background, ecological utility, and quality of life [8]
In order to objectively reflect the ecological characteristics of ecological red line (ERL) areas in Beijing, which was mainly dominated by mountainous areas, the application of remote sensing data at a high resolution was important for the improvement of model calculation and spatial heterogeneity
Summary
Ecosystem services have become a hotspot of interdisciplinary research because of their integrated characterization of natural system structure and function, and the comprehensive reflection of natural and social system feedback mechanisms [1,2,3,4] Among their main topics, ecological processes are the foundation, impact mechanism and trade-offs/synergy are the core, and coupling and improving human well-being is the goal. The accurate assessment of ecosystem services helps to determine the important areas of ecological protection and provides scientific suggestions for the protection of the ecological environment This Special Sssue compiles contributions on research related to the abovementioned various aspects of remote sensing in ecosystem services. A short summary of the varied contributions to this special issue is presented
