天山南坡草原荒漠多刺锦鸡儿(Caragana spinosa)灌丛空间分布研究

Spatial Distribution Patterns of Caragana Spinosa Population in Alluvial Fan Plains of Grassland on Southern Sope of Tianshan Mountin

采用样方和植物踏查法对天山南坡山前荒漠冲积扇平原锦鸡儿灌丛空间分布格局进行研究。结果发现锦鸡儿灌丛群落植物分属12科、19属,21种;其中豆科植物占9.52%、禾本科植物占14.29%、藜科植物占19.05%、菊科植物占14.29%、莎草科植物占0,杂类草植物占42.86%;锦鸡儿灌丛群落中的多刺锦鸡儿(Caragana spinosa)、浩罕彩花(Acantholimonkokandense)、盐穗木(Halostachys caspica)、驼绒藜(Ceratoideslatens Revealet)、琵琶柴(Reaumuria soongonica)和无叶假木贼(Anabasis aphylla)呈集群分布,趋于随机分布,多刺锦鸡儿灌丛属稳定的群落。

By using field survey and the method of grid contiguous quadrats the Caragana spinosa community and spatial distribution patterns were studied in alluvial fan plains of grassland on Southern slope of Tianshan Mountain. The results showed that the desert rangeland was made of 12 families, 19 genera and 21 species. The dominant species of shrub was Caragana spinosa. The herbage of dominant species was Artemisia frigida . The shrubs was made of 9. 52% Legurninosae, 14. 29% Poaceae , 19. 05% Chenopodiaceae , 14. 29% Asteraceae , and 42. 86% forbs. C. spinosa, Acantholimon kokandense, Halostachys caspica, Ceratoideslatens Revealet, Reaumuria soongonica and Anabasis aphylla were Congregation, and tendency to random distribution, C. spinosa shrub was stable community.
