New technologies for grassland diagnosis help in countering grassland deterioration. According to grassland and its types Indicator plant species have to be chosen. Relations between grazing pressure and species rearing should be measured by quantifying mathematical approach. Measures for protection of grasslands are proposed should include agro-ecological measures such as grassland monitoring through the use of GIS (Geographical Information system). The reliable and real-time monitoring enables accurate management of grasslands through the use of novel IT systems and satellites etc. Grasslands exist in the wider area in China, nearly it covers 40% of the national land area.
