Dynamic Variation of Ecosystem Services Value under Land Use/Cover Change in the Black Soil Region of Northeastern China

Abstract

A better understanding of the dynamic variation in the ecosystem service value (ESV) under land use/cover change (LUCC) is conductive to improving ecosystem services and environmental protection. The present study took Landsat TM/ETM remote sensing images and socio-economic statistic data as data sources and extracted land-use data using RS and GIS technology at 5-year intervals from 1990 to 2020. Then, we interpreted the spatio-temporal characteristics of LUCC and analyzed ESV changes using the value equivalence method in the black soil region of northeastern China (BSRNC). The main results showed that land use changed significantly during the study period. Cultivated land continued to expand, especially paddy areas, which increased by 1.72 × 106 ha, with a relative change of 60.9% over 30 years. However, grassland decreased by 2.47 × 106 ha, with a relative change of −60.6% over 30 years. The ESV showed a declining trend, which decreased by CNY 607.96 million during 1990–2020. The decline in forest and grassland caused a significant decline in the ESV. Furthermore, the ESV sensitivity coefficients were less than one for all of the different categories of ecosystem services. LUCC has a considerable impact on ESV in the BSRNC, resulting in ecosystem function degradation. As a result, future policies must emphasize the relationship between food security and environmental protection in situations of significant land-use change.

Spatiotemporal Conflict Analysis and Prediction of Long Time Series Land Cover Changes in the Black Soil Region of Northeast China Using Remote Sensing and GIS

“…The reason for this phenomenon was that the LCCS system contained more similar land classes, forest was divided into evergreen broad-leaved forest, deciduous broad-leaved forest, evergreen coniferous forest, deciduous coniferous forest, and mixed forest, and there was often more serious confusion among similar land classes [89,90]. The dynamic monitoring and analysis of land cover in this paper can also provide some references for surface change in the black soil region of China [103,104].…”

Lessons Learnt from the Influencing Factors of Forested Areas’ Vulnerability under Climatic Change and Human Pressure in Arid Areas: A Case Study of the Thiès Region, Senegal

“…According to the literature, unregulated urban development poses a significant risk to groundwater quality [1] and exerts critical pressure on natural resources. Moreover, changes in the functioning of the Earth's ecological systems present a significant threat to human survival [2]. For instance, issues such as food security are closely tied to the protection of cultivated land [3] and depend, in part, on the sustainable use of natural resources [4].…”

“…As an ecosystem service value, agricultural land provides multiple and diverse contributions to socio-economic development. Or, ecosystem service value is indispensable when balancing the need for food production and ecological protection because it can clarify a region's environmental assets and values (Li et al, 2022).…”
