摘要: 目前我国草地大面积退化、沙化,生产力下降,环境恶化,生物多样性减少,直接威胁牧区经济的发展,如何管好、用好草地资源已成为亟待解决的问题.景观生态学是一门新兴的综合性交叉科学,在草地管理中有着重要的应用前景.文中以草地景观生态研究中的理论、方法和应用为主线,综述了国内外有关草地景观生态研究的最新进展,总结了草地景观格局、生物多样性、景观退化与恢复、景观美学价值等国内外研究热点的研究状况,概括了国内外草地景观研究方法,并结合国外草地管理的方法和措施,从各个角度为决策者提供合理建议.

Abstract: China's grassland is confronted with a mass degradation, desertification, dramatic declining of productivity, environmental deterioration, and rapid loss of biodiversity, which directly threaten the sustainable development of pasture areas. This situation implies that proper management of grassland is essential in China. Based on abundant literatures in landscape ecological research of grassland, this paper summarizes and analyzes the latest progresses in this field in both China and abroad. Studies on landscape pattern, biodiversity, landscape degradation and restoration, and landscape aesthetic value as well as the advances in research methods are focused, aimed at providing references to research in this field in China. Some management strategies from abroad are also summarized to offer references to the Chinese counterparts.

Key words: Grassland landscape, Landscape pattern, Biodiversity, Landscape degradation and restoration, Landscape aesthetic value, Coffea arabica, deficit irrigation, shade cultivation, photosynthetic characteristics, yield, water-radiation use
