Monitoring and Assessing Land Use/Cover Change and Ecosystem Service Value Using Multi-Resolution Remote Sensing Data at Urban Ecological Zone

Abstract

An urban ecological zone (UEZ) is an important part of a city, focusing on environmental conservation and ecological economic development simultaneously. During the past decade, the urban scale of Xi’an city in China has been expanding, and the population has been increasing rapidly. This dramatic change is a huge challenge to urban sustainability. It puts forward higher requirements for the construction of an UEZ. Under different spatial resolution scales, this study adopted Landsat8-OLI and gaofen-2 (GF-2) satellite high-resolution remote sensing data to interpret the land use/cover change (LUCC) of the Weihe River UEZ. The ecosystem service value (ESV) was assessed, and the ecological effect was analyzed based on LUCC. The results showed that the spatial distribution of land types in the Weihe River UEZ changed significantly from 2014 to 2020. The construction land gathered to the southeast. Especially, the vegetative land (i.e., forestland, grassland and other green land) and water body showed a slightly increasing trend since the official establishment of the UEZ in 2018. The cultivated land area gradually reduced, and the vegetative land area tended to be concentrated as well as expanded. Through the interpretation of GF-2 remote sensing data, the ESV at the Weihe River UEZ showed a downward trend in general. The high-value areas were mainly distributed in the Weihe River and its surrounding beach areas, which were greatly affected by river water scope. Construction land normally had low ESV, and it was affected by human activities obviously. Therefore, the development of urban construction had significant impacts on the Weihe River UEZ.

Coupling of Changing Trends in Population and Construction Land in Traditional Rural Areas and Spatial Patterns in Urban–Rural Development, 2016–2021: A Case Study of Heilongjiang Province, China

“…mca.gov.cn/map (accessed on 11 September 2023)); these were overlaid with the township data of Heilongjiang Province to obtain the urban built-up area data. The comprehensive urban attractiveness dataset consists of three parts-employment environment, living environment, and ecosystems-including 19 indicators [30][31][32][33] (Table 2), and the data were all obtained from the "Heilongjiang Statistical Yearbook 2022" (https://kns.cnki.net/knavi/ yearbooks/YHLTN/detail?uniplatform=NZKPT (accessed on 3 November 2023)). We aimed to study the spatial and temporal changes in population and construction land use at the township scale.…”

Research on the coordinated relationship between human activities and ecosystem service value in the Arid Region, Northwestern China

“…LUCC influences the structure and functioning of ecosystems, leading to changes in the delivery of ecosystem services. (Li et al, 2018;Liu et al, 2022;Duan et al, 2023). In recent years, a number of academics have recognized the significance of exploring the relationship between changes in LUCC and the ESV.…”

Analysis and prediction of land use change characteristics in Nanchang from 2005 to 2035

“…Remote sensing data and models enrich the method to study urban land use change (Liu et al, 2022;Wang et al, 2022). Yi (1993) successfully determined the transfer probability of land use type by remote sense image, and predicted the change trend of land use type by using the Markov chain model, which put forward reasonable suggestions for the future development strategy of the city.…”
