草原生态建设与草地灌溉耦合效应研究

草地退化、沙化是我国牧区脆弱生态系统失衡急需整治的重大环境问题。在分析草地生态环境现状的基础上，从提高草地综合生产力和恢复保护草地植被改善生态环境二个方面，阐述了牧区发展灌溉草业的必要性和可行性；提出各类草地灌溉草业发展模式；对如何确定灌溉发展规模和灌溉草业与生态恢复的耦合效应作了探讨，提出相应的定量计算方法。

Study on Coupling Effect Between Grassland Ecology Construction and Grassland Irrigation

Grassland sand desertification and degradation is a great environmental problem of eco-system unbalance which should be paid more attention to in the pastoral areas of our country.On the basis of analyzing the status quo of grassland eco-environment, from following two aspects of increasing grassland productivity, resuming and protecting grassland vegetation and improving ecological environment,the necessity and feasibility of developing irrigation grass industry in pastoral areas are expounded,development models of irrigation grass industry on different type grasslands are put forward,as well as how to define the irrigation scale and the coupling effect between irrigation grass industry and ecology renovation and advance corresponding quantitative calculating methods.
