The Power of Regeneration: Lessons from a Degraded Grassland

Restoration Ecology, 2007
Abstract To gain insight into mechanisms controlling ecosystem regeneration, we investigated a grassland that was heavily polluted by a phosphate fertilizer factory between 1960 and 1990. Abiotic and biotic filters that influenced species assemblage and succession were monitored and restoration approaches assessed. Studies included the investigation of

Grassland degradation in the Western of Songnen plain

2011 19th International Conference on Geoinformatics, 2011
Based on RS and GIS techniques, three-period (1986, 1995, 2000) remote sensing images are interpreted in order to gain spatial information about grassland landscape in the Western of Songnen plain, then spatial-temporal dynamics of grassland and the natural, human factor of grassland degradation are analyzed.

Research Progress of the Grassland Carbon Cycle and Grassland Degradation in China

2019
Grasslands, one of the most common vegetation types in the world, account for nearly 20% of the global land surface. The vast land cover and carbon sequestration potential make it become the important composition of the terrestrial carbon cycle. In China, grasslands mainly locate in the arid and semi-arid areas in the northwest and the Tibetan Plateau ...

A device for mechanical remediation of degraded grasslands

Soil and Tillage Research, 2012
Abstract Conventional tillage practices are traditional methods to restore the degraded grasslands. However, the risk of wind and water erosion increases dramatically. To remedy these degraded grasslands and conserve soil and water, a rotary cutting mechanism named soil-gashing and root-cutting device was designed and tested in typical degraded ...

Deciphering the role of rodents in grassland degradation; A review

Journal of Environmental Management
Grasslands are vital ecosystems that play a crucial role in providing numerous services to both humans and the environment. Healthy grasslands are characterized by diverse vegetation, efficient soil, and abundant microbial communities, which enable them to function effectively. However, these ecosystems are at risk of degradation due to various factors,

Current status of grassland degradation and measures for grassland restoration in northern China

Chinese Science Bulletin, 2018
Grasslands in northern China are traditionally important bases for livestock production and ecological barriers for China. However, these grasslands degraded extensively due to global climatic change and poor management during the past half century. Such grassland degradation leads to dramatic declines in multiple ecosystem functions.

Impact of grassland degradation on the distribution and bioavailability of soil silicon: Implications for the Si cycle in grasslands

Science of The Total Environment, 2019
Grassland ecosystems play an important role in the global terrestrial silicon (Si) cycle, and Si is a beneficial element and structural constituent for the growth of grasses. In previous decades, grasslands have been degraded to different degrees because of the drying climate and intense human disturbance.

Spectral characteristics of alpine grassland and their changes responding to grassland degradation on the Tibetan Plateau

Environmental Earth Sciences, 2015
Remote sensing is used as the indispensable technology in alpine grassland degradation assessment especially at regional scale on the Tibetan Plateau. However, the lack of field spectral data, as the foundation of remote sensing, due to the formidable natural and climate conditions hinders the understanding of spectral characteristics of alpine ...

Grassland degradation and livestock rearing in Lesotho

Journal of Southern African Studies, 1995
This study is written in the context of marked intervention by external agencies, during the last 20 years. This has taken place within the broad concept of ‘sustainable development’, with the stated desire to ‘develop’ Lesotho's livestock economy, and to conserve the country's grasslands. The paper emphasises the need for social scientific analyses to

Analysis of meteorological factors on grassland degradation in Hulunbeier

2011 International Conference on Remote Sensing, Environment and Transportation Engineering, 2011
This paper, using nearly 50 years of meteorological data from four national weather stations of Hulunbeier grassland, analyzes the impact of the changes of temperature, precipitation and evaporation on grassland degradation, the results show that: temperature and evaporation increased significantly and precipitation changed slightly in the study area ...
