[Hyperspectral remote sensing monitoring of grassland degradation].

Guang pu xue yu guang pu fen xi = Guang pu, 2015
The distributing of China's grassland is abroad and the status of grassland degradation is in serious condition. So achieving real-time and exactly grassland ecological monitoring is significant for the carbon cycle, as well as for climate and on regional economies.

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.

Restoration of Neotropical grasslands degraded by quarrying using hay transfer

Applied Vegetation Science, 2013
AbstractAimThe campos rupestres are species‐rich tropical mountain grasslands in southeast Brazil that are threatened by mining and quarrying. Eight years following a strong disturbance (i.e. quarrying for gravel exploitation during the asphalting of highway MG‐010), spontaneous succession did not occur on degraded areas.

Grassland degradation alters plant and soil biodiversity–multifunctionality relationships

Nature Plants
Biodiversity is known to promote ecosystem multifunctionality (EMF), but how grassland degradation influences the relationship between biodiversity and EMF remains unclear. Here, using paired observations at 44 sites (a total of 792 sampling quadrats) along a 2,600 km transect, we test how moderate grassland degradation influences 20 surrogates of ...

Assessing the effects of climate variation and human activities on grassland degradation and restoration across the globe

Ecological Indicators, 2019
While quantitative assessment of ecosystems degradation is quite addressed in the literature, quantitatively separating the relative contribution of climate variation and human activities to grassland ecosystem degradation is still limited, although well

Grassland degradation and livelihoods in China's western pastoral region

China Agricultural Economic Review, 2010
PurposeChina has embarked on a major concerted strategy to arrest grassland degradation and livelihood problems in the western pastoral region. The paper aims to provide a framework through which this strategy can be understood and refined into the future.Design/methodology/approachThe paper is based on a typology of grassland policies – technical ...

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 ...

Effects of microbial agents on soil microecology of alpine desertified grassland and degraded grassland

Comprehensive Plant Biology
Desertified and degraded grassland can severely damage the soil microbial structure, accelerating desertification and degradation. Microbial agents can improve soil fertility, and even play a very important role in controlling soil desertification, promoting grass?land sustainability, and enhancing productivity.
