The History,Disciplinary System and Mission of Grassland Science in the New Era
Grassland science is the subject to study the traits and functions of grassland and its component,and the utilization,conservation,and improvement of grasslands.Grassland science in China was developed on the basis of Ren Jizhou's theory of grassland agro-ecosystem and integration of the characteristics of range science,forage science and science of grassland agriculture.A discipline system of grassland science with Chinese characteristics has been established in China,including range science,forage science,management of grassland pest,turf science,and economics and management of grassland agriculture.On the basis of briefly summarizing the history of grassland science,combined with the new progress in the multifunctionality,multiserviceability and multi-functional management of grassland ecosystems in this century,it is proposed to add science of grassland agriculture as a new sub-discipline of grassland science.Grassland science is facing major national demands and challenges in the new period:including forage security is essential for national food security;the establishment of a big food concept and the vigorous development of grassland agriculture contribute to the diversified food supply system;and the construction of the national ecological barrier plays a supportive role in the cause of grassland protection and restoration.This paper further summarizes the scientific and technological issues behind these demands.The major needs of the country are both opportunities,challenges and missions for grassland science.
