人工绿洲外围荒漠植物组成与生活型研究

Study on Desert Plant Composition and Life Forms in the Peripheral Region of Artificial Oasis

通过调查,在克拉玛依农业综合开发区外围共采集到高等植物119种,分属27科,90属,以藜科和菊科植物为主,大部为旱生或超旱生灌木、半灌木、多年生草本和一年生草本以及中生的一年生短命植物。植物生活型以草本植物为主,高达81.51%,其中短命植物16.81%,1年生草本植物占29.41%,多年生草本植物占35.29%;木本植物种类较少,灌木占6.72%,小灌木和半灌木占10.08%,小乔木占1.68%。

By investigation,we collected ,rod identified 119 species of higher plants belonging to 27 families,90 genera in study area. Among them, Chenopodiaceae and Compositae are the two most dominant families. Most species have drought resistance ability including shrubs, nanoshrubs, therophytes. Herbage plant is the dominant life forms, accounting for 81.51% of the total.Among herbage plant,ephemeral plant accounting for 16.81% ,annual herb accounting for 29.41%, perennial herb accounting for 35.29%.Woody plants account for lower percentage.Among woody plant,shrubs, nanoshrub and tree accounting for 6.72%, 10.08% and 1.68% respectively of the total plant.
