Degree of desertification based on normalized landscape index of sandy lands in inner Mongolia, China

open access: yes, 2020
Desertification is one of the most serious ecological environmental problems over the past several decades in the arid regions. The quantitative assessment of the desertification degree in sandy lands has also been an essential part of landscape ecology.

The Relationship between Urban Sprawl and Farmland Displacement in the Pearl River Delta, China

open access: yesLand, 2013
China is rapidly urbanizing and will inevitably face trade-offs between promoting economic growth through further urbanization and protecting fertile farmland against accelerated urban expansion. This paper presents how this dilemma is being addressed in

Do We Need More Urban Green Space to Alleviate PM2.5 Pollution? A Case Study in Wuhan, China

open access: yesLand, 2022
Urban green space can help to reduce PM2.5 concentration by absorption and deposition processes. However, few studies have focused on the historical influence of green space on PM2.5 at a fine grid scale.

Quantifying the Scale Effect of the Relationship between Land Surface Temperature and Landscape Pattern

open access: yesRemote Sensing, 2023
The spatial scaling of patterns and processes is a hot topic of research in landscape ecology, and different scales may yield completely inconsistent results. Therefore, to understand the impact of the scale effect on urban heat island effect, this study
