Abstract:

Grassland investigation, monitoring and evaluation (GIME) is the foundation for understanding the current situation and development dynamics of grassland resources. China’s GIME system has problems of a weak foundation, slow update and tardy development, which lead to an obscure information base and unclear definition of trends relating to grassland resources in China. Therefore the need for more sophiticated management of grassland can’t be met. The wider management of China’s grassland resource is at the stage of institutional reform and functional transformation. Based on experience from countries that possess abundant grassland resources, optimization and refinement of a GIME system would be conducive to the improvement of national grassland oversight. This study systematically summarizes the experience from construction of GIME systems in America, Canada and Australia and this experience offers valuable guidance for development of grassland supervision systems in China. International experience implies that certain practices, such as implementing multi-time scale fine monitoring, setting ample monitoring indicators, researching and applying advanced technologies, building a field observatory network, developing an integrated data management platform and a mechanism of data sharing, expanding the application range of outcomes, forming professional technical teams, and encouraging public participation, will better fulfill demands for multi-objective and more sophisticated grassland management for different stakeholders, and as such which deserve widespread promotion.

Key words: grassland resources, grassland investigation, grassland monitoring, grassland evaluation, supervision system
