热带草原也叫热带稀树草原,受赤道低压带和信风带交替控制,当赤道低压带控制时,盛行赤道气团,形成闷热多雨的湿季;当信风控制时,盛行热带大陆气团,形成干旱少雨的干季。湿季时,遍地生长稠密的高草和灌木,杂有稀疏乔木,即稀树草原景观;干季来临后,土壤干裂,草丛枯黄,大部分树木落叶,动物向有水草处迁移。非洲的热带草原禾本科草类丰富,动物众多,是发展畜牧业和建立动物自然保护区的良好基地。
The savannah, also known as the savannah, is controlled alternately by the equatorial low pressure belt and the letter wind belt. When the equatorial low pressure belt is in control, the equatorial air mass prevails, forming a hot and humid wet season. When the letter control is carried out, the tropical continental air mass is predominantly droughts Dry season without rain. During the wet season, the densely-grown tall grasses and shrubs grow everywhere, with sparse trees, that is, the landscape of savannah. After the dry season comes, the soil is dry cracked, the grass is yellowish, most of the trees are deciduous, and the animals are migrated to aquatic plants. African savanna grass rich species of grass, animal abundance, is the development of animal husbandry and the establishment of animal nature reserve a good base.
