Trough mastering background information of Yunnan province grassland resources utilization and ecological conditions to improves grassland elaborating management capacity, it carried out grassland res...
Grassland ecology experiments in remote locations requiring quantitative analysis of the biomass in defined plots are becoming increasingly widespread, but are still limited by manual sampling methodo...
River restoration projects, which aim at improved flood safety and increased ecological value, have resulted in more heterogeneous vegetation. However, they also resulted in increasing hydraulic rough...
Remote sensing of crop biomass is important in regard to precision agriculture, which aims to improve nutrient use efficiency and to develop better stress and disease management. In this study, multi-...
The study shows that leaf area index (LAI) and canopy chlorophyll content can be mapped in a heterogeneous Mediterranean grassland from canopy spectral reflectance measurements. Canopy spectral measur...
The particular flood recessional ecosystem in Poyang Lake provides young and high quality grasses in late autumn and wintertime, and attracts millions of migratory birds to over winter. Grasslands alo...
Grassland degradation is a complicated process and result of multi-system interaction. Observation on grassland vegetation growth and change is of critical importance to grassland resource management ...
In our study we classified grassland vegetation types of an alkali landscape (Eastern Hungary), using different image classification methods for hyperspectral data. Our aim was to test the applicabili...
Dry grassland sites are amongst the most species rich habitats of Central Europe. In Switzerland, they are home to a large number of plant and animal species that are classified as endangered or thre...
Potential evapotranspiration (PET) is an important parameter of water budgets at different spatial scales and is a critical variable for understanding regional biological processes. It is often an i...
The identification and surveillance of agricultural management and the measurement of biophysical canopy parameters in grasslands is relevant for environmental protection as well as for political an...
A Bayesian method was used to fit the Shuttleworth–Wallace model to half-hourly measurements ofevapotranspiration (ET) with the eddy covariance technique from an alpine grassland on the Qinghai-Tibeta...
As a consequence of the wide-spread application of digital geo-data in geographic information systems (GIS), quality control has become increasingly important to enhance the usefulness of the data. ...
In many publications the performance of different classification algorithms regarding to agricultural classes is evaluated. In contrast, this paper focuses on the potential of different imagery for ...
