贵州木本淀粉植物资源及其自然分布

Woody Starch Plants in Guizhou: Species, Distribution and Utilization

通过1985-1990年野外考察,贵州木本淀粉植物共计108种、1变种。其分布与植被分布表现出一致性,具相似的规律。根据木本淀粉植物生境的异同,将其分布分为4个类型:高原分布、岩溶分布、山地分布和河谷分布,不同的地理区域其主要分布类型亦不同。高原的垂直变化呈现偏干性木本淀粉植物替代偏湿性木本淀粉植物的规律,山地的垂直变化呈现落叶木本淀粉植物替代常绿木本淀粉植物的规律,

There are 108 species and 1 variety of woody starch plants in Guizhou, whose distribution accords with that of the vegetation. Classified by habitat, these plants can be divided into 4 dispersion patterns, i.e., plateau pattern, karst pattern, mountain pattern, and river valley pattern. The main dispersion pattern differs with the geographic locations. While in the plateau the increase in altitute tends to chang the hygronasty plants into the xeronasty ones, in the mountain the increase in altitute usually results in the replacement of evergreen plants by the deciduous ones.
