摘要：

沙冬青为干旱荒漠常绿灌木，是我国首批重点保护珍稀濒危植物，具有抗旱抗寒性能强、防风固沙效果好、药用价值高等特点。但由于本身分布区狭小，病虫害严重，加之人为破坏，天然沙冬青已趋于濒危，又没有形成大面积的人工种群。本文以生长于景泰县境内的石质山坡沙冬青群落为研究对象，通过收集资料、野外考察和调查、室内样品化验，确定了不同坡向沙冬青群落的物种组成、数量特征及其林地土壤粒度、水分及化学性质等，为科学合理的人工保护、繁育沙冬青提供必要的理论依据。

Abstract:

Ammopiptanthus is evergreen shrub in arid desert area.It is rare and endangered plant,need to key protection,which is first given official approval in China.That has strong performance of drought cold, good effection of sand-fixing and high medicinal value etc. But natural Ammopiptanthus is endangered, because of their narrow distribution area, serious plant diseases and insect pests, coupled with vandalism, also did not form large areas of artificial population. This paper Choosed Ammopiptanthus community,growing in stony hill of jing tai for the research object, Through the collection of information, field surveys and investigations, indoor samples for testing, defined the species composition, quantitative Features,and the forest soil particle size, soil moisture and chemistry etc.of the different aspect Ammopiptanthus community, providing the necessary theoretical basis for scientific and rational.artificial protection and breeding of Ammopiptanthus.
