灌木的生态特性与生态效能的研究与进展

The Progress and Perspective of Research on the Ecological Characteristics and Benefits of Shrub

文章论述了国内外在灌木的生态性和生态效能方面的研究概况,介绍了灌木的主要特征及其对生长环境和干扰响应的生态学论述,并分别就干旱荒漠区灌木、草牧场地灌木、盐碱地灌木和森林区次生灌木四种主要灌木类型进行了说明。另外主要从生物多样性、水土保持、防风固沙、土壤改良、改善气候等五个方面阐述了灌木林的生态效能研究现状。最后指出灌木今后的重点研究方向。

The advance of research on the ecological characteristics and ecologial benefits were presented. The main features of shrub and its response to the environments and disturbance were expounded in ecological standpoint, which were separately presented for four shrub type, such as arid desert shrub, shrub steppe, saline-alkali shrub and secondary shrub. Subsequently the ecological benefits of shrub were discussed from five aspects, such as biological diversity, soil and water conservation, wind-shelter and sand fixtation, soil amelioration and environment cleaning. Finally the important research aspects for shrub were put forward.
