Study on Changes of Ecosystem Services Value and Driving Factors in
Yellow River Delta
Abstract
Wetlands are precious natural resources with huge ecosystem services
value behind them. Understanding the temporal and spatial variation of
wetland ecosystem services value and its driving forces is essential for
sustainable development and human well-being. Taking the Yellow River
Delta as an example, this article calculated ecosystem services values
based on equivalent factor method from 2000 to 2020 and analyzed the
spatiotemporal characteristics of ecosystem services value by spatial
statistics analysis; used Geodetector to detect and interact with the
driving factors. The results show the following: (1) The reduction of
wetland area directly caused the reduction of ecosystem services value,
and the distribution of ecosystem services value in the wetland area
shows agglomeration phenomenon. (2) NDVI, GDP and humidity were the main
driving factors affecting the change of ecosystem services value, while
elevation, slope and aspect had little effect. (3) The main factors
affecting the ecosystem services value are all related to vegetation.
(4) When temperature, NDVI, precipitation, humidity, GDP and population
density interacted, they had a greater effect on ESV than when they
acted alone. Our research results can provide reference information for
the world’s delta regions and provide scientific advice for ecological
environment governance to promote the healthy development of the
ecological environment.
