克拉玛依农业综合开发区外围荒漠种子植物区系研究

Seed Plants Flora in the Outer Desert Area of Karamay Agricultural Comprehensive Developmental Region

调查研究表明:克拉玛依农业综合开发区外围荒漠有种子植物27科90属119种。对该区种子植物区系进行了统计分析,结果表明:①科属构成简单,单种科、少种科和单种属、寡种属占比例大;②科属的地理成分中,温带成分占优势;③属的区系成分有7个分布型和6个变型,其中地中海、西亚至中亚分布型占优势,包含属数占本区系总属数的35.56%,占新疆同分布型种子植物总属数的22.54%。表明本区属于中亚荒漠。

The investigation and study indicated that there were 27 families, 90 genera, and 119 species in the outer area of Karamay Agricultural Developmental Region. This article had carried on the statistical analysis as follows for seed plants flora in this area, the results were： （1） The constitution of families and generas was simple.The single families and small families accounted for bigger proportion as well as genera. （2） Factors of the temperate zone got advantage in the geography composition of families and genera. （3） Floral composition of genera consisted of 7 distribution types and 6 variable types, The distribution types were superior in the area from Mediterranean Sea, west Asia to the central Asia, whose genera was 35.56 % of total in this area, and 22.54 % of total genera of same distribution types of Xinjiang, it showed the area belonged to desert of mid Asia
