Effects of Land Use Changes on Ecosystem Service Value in Xiangjiang River Basin, China

Abstract

The study of land use change and the evolution of ecosystem service values (ESV) is important for optimizing the allocation of regional land resources and achieving sustainable development, but traditional land use analysis methods cannot dig deeper into the information on the internal transitions between different land types. Therefore, in this paper, we use the component analysis and Intensity Analysis methods to systematically analyze the land use landscape changes at multiple levels. In addition, the spatial and temporal dynamic characteristics of ESV in the Xiangjiang River Basin are carved with the help of equivalence factors and GIS spatial analysis methods, which reveal the response of ESV changes to land use changes in the Xiangjiang River Basin in the past four decades. Our results showed that, (1) in the past 40 years, the intensity of land use change in the Xiangjiang River Basin has been increasing, mainly in quantity and shift. The increase of built-up and bare land and the decrease of cultivated land are stable and active, and the loss of forest land is large, but it is dormant. The loss of cultivated and forested land flows mainly to built-up land. (2) In the Xiangjiang River Basin, ESV increases first and then decreases, mainly in the middle and high grades and changes faster in the east. (3) The cross-sensitivity coefficient reflected that the net conversion of cultivated land to forest land and water area had a promoting effect on ESV. Our results provide important knowledge to inform land use decisions and facilitate sustainable development in the Xiangjiang River Basin.

Ecosystem Service Value Assessment of the Yellow River Delta Based on Satellite Remote Sensing Data

“…Land use/land cover change (LUCC) inevitably impacts the ESV [56]. Values corresponding to different land use types were extracted based on land use maps of the YRD in 1990, 2000, 2010, and 2020 (Figure 6).…”

“…Understanding LUCC is crucial in protecting the regional ecological security pattern [52]. Forests, water areas, and grasslands with high coverage have a good ecosystem service function [86,87]. The building area in the CZTMA increased from 526.4 km 2 in 2000 to 1422.9 km 2 in 2020 (Table 6).…”

The Ecosystem Service Value Calculation and Distribution of Ecological Compensation Based on Land Utilization—Take Hainan Rainforest National Park as an Example

“…Finally, we obtained the ecosystem service value coefficients of different local ecosystem types based on the basic equivalence table, and further calculated the ecosystem service value of land use types and the service price value of individual functions of Hainan Rainforest National Park from 2001 to 2019 (as shown in Table 1). The calculation formula is [23] :…”
