Using Beijing city as a case, firstly the Impervious Surface Percentage (ISP) are extracted by Linear Spectral Unmixing method in the paper, and the accuracy was tested by aerial photograph with high spatial resolution. Then the information of vegetation percentage, Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST) parameters were extracted from HJ-1B remote sensing...
Natural and anthropogenic (e.g. land cover/land use change) processes can lead to ecosystems change dramatically on timescales from years to decades. Especially, land cover/land use changes by mining can have drastic impacts on ecosystems and basin-wide water budgets. Phosphate rock is an important strategic resource. China and U.S. are two major phosphate reserves counties in the world and both facing...
Eco-physiological characters of two C. angustifolia water ecotypes, typical meadow C. angustifolia and marsh meadow C. angustifolia, were studied by field survey and controlled experiment. Under natural field, 1) species diversity in marsh meadow C. angustifolia community was higher than that in typical meadow C. angustifolia community, but C. angustifolia population biomass in typical meadow C. angustifolia...
Desertification is one of the most serious environmental, social and economic problems in the contemporary world including China that has aroused close concerns of many countries' governments, and China as well. The paper summarized the current status, distribution, dynamic evolvement by remote sensing as monitoring method assisted with field investigation, and forecast the development trend of desertification...
