草地景观生态研究的几个热点问题及其进展

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.
