Impact of Land Use/Cover Change on Yangtze River Delta Urban Agglomeration Ecosystem Services Value: Temporal-Spatial Patterns and Cold/Hot Spots Ecosystem Services Value Change Brought by Urbanization

Abstract

Land use/cover change (LUCC) from increased urbanization significantly impacts regional ecosystem services. Based on a cold/hot spots analysis, this paper used grain yield, food prices, price index statistics, and a land use thematic map to study the impact of LUCC on four ecosystem services values (ESVs) in the Yangtze River Delta urban agglomeration, and determine the spatial differences resulting from the rapid urbanization LUCC. The correlation between the four ecosystem services was then studied and sensitivity analyses conducted to investigate whether any changes in the ESVs could lead to unacceptable unit value transfer uncertainties. It was found that most urban land was converted from farmland, and that before 2000, the total ESVs and the regulating services values (RSVs) increased significantly, after which it declined, the provisioning services values (PSVs) declined year on year, the habitat services value (HSV) and cultural and amenity services value (CSV) declined sharply after 2000, and the spatial distribution of the four ESVs were significantly different. Over time, it was found that the hot spots were shrinking and the cold spots were spreading. The provisioning services were found to be negatively correlated with habitat services and cultural and amenity services, the regulating services were weakly positively correlated with the provisioning services and significantly positively correlated with the habitat services and cultural and amenity services, and the habitat services were significantly positively correlated with cultural and amenity services. In the Yangtze River Delta urban agglomeration, the water area is the most important for the total ESVs, followed by non-bush forest. Paddy field is ranked third. Dryland, bush, grassland, and wetland are less important. The importance of barren land is almost zero. This research provides the government with a scientific basis from which to formulate spatial planning and environmental protection policies for ecological sustainable development in the Yangtze River Delta urban agglomeration.

Impact of landscapes Dynamics and Intensity on Ecological Land in Major Ethiopia Cities

“…The overall accuracy of the LULC change dataset was 86.71% according to field survey data and records. This result is aligning with the recommended value of many scholars (Ha et al, 2020;Li et al, 2019).…”

The Impact of Land Use Change on Ecosystem Service Value in the Upstream of Xiong’an New Area

“…The basic equivalent value of construction land is not calculated in the value equivalent factor table. We determined that the base equivalent value of the construction land was 0 according to related research [29,30]. Then, we settled the correction coefficient for ESV of one standard equivalent factor as 0.70, which was the ratio of grain yield per unit area in the study area (3495.80 kg/hm 2 ) to those in the whole country (4973.60 kg/hm 2 ) in 2010.…”

Spatiotemporal Dynamics of Ecosystem Service Value Determined by Land-Use Changes in the Urbanization of Anhui Province, China

“…The revised ecosystem services include four primary types-provisioning services, regulating services, supporting services, and cultural services-and 11 secondary types-food production, raw materials production, water supply, gas regulation, climate regulation, hydrological regulation, environmental purification, soil formation and retention, maintain nutrient cycling, biodiversity protection, and recreation and culture. In addition, they developed and improved the equivalent factor of ESV per unit area in China, which has been used to evaluate the ESV in forest land [25], grass land [26], wet land [27], and areas of urban agglomeration [28]. This ESV assessment method is easy to use and provides highly comparable results.…”
