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.

Impact of grassland degradation on soil multifunctionality: Linking to protozoan network complexity and stability.

Science of the Total Environment
Soil protozoa, as predators of microbial communities, profoundly influence multifunctionality of soils. Understanding the relationship between soil protozoa and soil multifunctionality (SMF) is crucial to unraveling the driving mechanisms of SMF. However,

Integrating future grassland degradation risk to improve the spatial targeting efficiency of payment for ecosystem services.

Journal of Environmental Management, 2022
Spatial targeting plays a key role in improving the efficiency of payment for ecosystem services (PES). However, the risk of grassland degradation after implementing PES increases uncertainty about the efficiency of PES.

Convolutional transformer attention network with few-shot learning for grassland degradation monitoring using UAV hyperspectral imagery

International Journal of Remote Sensing
In recent years, the desertification of grasslands has increased due to various factors, including both global warming and human activities. It is an essential basis for grassland degradation monitoring to monitor the dynamic change of desert grassland ...

Alpine grassland degradation in the Qilian Mountains, China — A case study in Damaying Grassland

Catena, 2016
Abstract Degradation of semiarid grassland and efforts to control that degradation have become pressing issues. However, the inherent characteristics of the grassland and the intertemporal nature of the problem complicate the analysis of degradation issues, and consequently, the search for more appropriate rangeland policies.

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 ...

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.

Impacts of nitrogen enrichment on vegetation growth dynamics are regulated by grassland degradation status

Land Degradation and Development, 2021
Plant phenological responses under global climate change is a hot topic in current ecological research. However, it also has comprehensive interactions with other anthropogenic environmental factors including nitrogen (N) enrichment owing to atmospheric ...
