Abstract

Accurate assessment and response analysis of land use and land cover change (LUCC), and ecosystem service values (ESV), are critical to regional ecological security and economic development. There is a lack of detailed reports on the impact of LUCC on the temporal and spatial evolution of ESV in Yinchuan City, which is inconsistent with the pilot urban design policy. This paper, using the LUCC data of Yinchuan City from 1980 to 2018, calculated the ESV, analyzed the temporal and spatial patterns of LUCC and ESV, and discussed the response of ESV to LUCC. The results show that, from 1980 to 2018, the building land increased significantly in Yinchuan City, as did the cultivated land. Meanwhile, grassland and bare land decreased, while forest and the water body remained stable. The spatial connectivity of the building land showed regular improvements, while the urban landscape developed in a regular and balanced direction. During the study period, the total ESV of Yinchuan City decreased by 0.75 × 109 yuan. This was due to the decrease in grasslands and the increase in building area. The supply, regulation and support of three types of services have a high correlation with different land types. The prosperity and progress of culture reduces the ESV value of cultivated land to some extent, while the change in land use type leads to the significant loss of ESV in Yinchuan City.

Highlights

Land use and cover change (LUCC) is a fundamental component of an environmental shift and a major determinant of sustainable development of productivity and human adaptation to global change [1]

Summary

Introduction

Land use and cover change (LUCC) is a fundamental component of an environmental shift and a major determinant of sustainable development of productivity and human adaptation to global change [1]. LUCC is of great significance for maintaining good ecosystem structure and sustainable development of productivity [2]. With the change in land use, the structure and function of the ecosystem are further affected [7]. Ecosystem is a unified whole that human beings rely on for survival. The long-term survival and development of human beings depend on life-sustaining products and services, which are all provided by the structure, process and function of ecosystem services [9]. An assessment of ecosystem service values (ESV) helps to identify problems early and to take measures in time so that health and ecological security is promoted [10]
