摘  要：
通过对临泽地区不同类型的盐碱地植物进行研究,揭示不同类型盐碱地植物群落的分布特征,结果表明,除20 cm土层土壤温度最高值出现在8月份,其他土层的土壤温度最高值出现在7月份,而最低值除了60 cm土层土壤温度出现在12月份,其他土层的土壤最低温度出现在1月份。轻度和中度盐碱地主要以藜科占绝对优势,其次为禾本科、茄科;而重度盐碱地以禾本科占绝对优势,其次为菊科和藜科;从样地物种组成来看轻度和中度的科属表现为单科单属,而重度盐碱地表现出优势科属比轻度和中度的要丰富。3个样地中共有荒漠盐碱植物种31种,其中灌木8种、草本23种,草本植物明显多于灌木。从灌木占物种数的比例来看轻度和中度盐碱地灌木较为丰富,从3个样地中草本占物种数的比例来看重度盐碱地草本植物较为丰富。

摘  要：
Through the study of different types of saline-alkali soil plants in Linze area, the distribution characteristics of different types of saline-alkali soil plant communities were revealed. The results showed that except for the 20 cm soil layer, the highest soil temperature appeared in August, the highest soil temperature of other soil layers appeared in July, while the lowest soil temperature, except for the 60 cm soil layer, appeared in December, and the lowest soil temperature of other soil layers appeared in January.The mild and moderate saline soils were dominated by chenopodiaceae, followed by gramineae and solanaceae, and the severe saline soils was dominated by gramineae, followed by compositae and chenopodiaceae. From the point of view of the species composition of the sample, the mild and moderate families and genera were shown as single families and single genus, while the severely saline-alkali land showed that the dominant family and genera were more abundant than the mild and moderate ones.There were 31 species of desert saline-alkali plants in the three plots, including 8 shrubs and 23 herbs. Herbs were obviously more than shrubs.In terms of the proportion of shrubs in the number of species, mild and moderately saline-alkali land shrubs were more abundant. In terms of the proportion of herbs to the number of species in the three plots, the severely saline-alkali land was more abundant.
