Abstract:
The grassland of more than 90% has degraded to some extent in recent decades i n China, especially the grassland in Inner Mongolia, Ningxia, Gansu, Qinghai, Xi njiang and Tibet degraded severely. The management department urgently needs to know how the meteorological influence on grassland vegetation growth，producti on, carrying livestock and ecological quality. The models about evaluating of me teorological conditions, predicting of grassland production and carrying livesto ck, and monitoring of ecological quality have been established by utilizing the fuzzy mathematics, collection operation, statistical analysis and “3S"technolog y. The used data in the model are grassland temperature, precipitation, sunlight hours, NOAA NDVI, grass biomass observation and so on. Theses models are used t imely in service. The good benefits are obtained. The application of northern gr assland ecological meteorological monitoring and predicting in 2007 is given. The result shows the models integrated many data resource and method advantage. The model results are close to the reality. The established synthetic technology can provide the scientific foundation for protection and restoration of grassland ecological environment.
