位于新疆天山南麓中段的轮台地区因独特的自然地理位置和生态环境孕育了较为丰富的植物物种资源，本课题组通过野外实地调查及查阅相关文献资料，对分布于该区的的野生种子植物的物种多样性及区系地理成分进行了系统地分析．结果表明：该区共有野生种子植物876种79科338属；科水平上，超过10种的科有17科，含种数672种，占总种数的76.7％，区系优势科现象明显；属水平上，单种属及寡种属占据优势，有304属，占总属数的89.9％；区系地理成分多样，区系性质以温带成分为主，其中科的分布类型有6个类型8个变型，温带成分占非世界分布总科数的56.4％；属的分布类型有13个类型16个变型，温带成分占非世界分布总属数的58.2％；新疆特有种有31种，占该区总种数的3.5％，比例相对较低．
位于新疆天山南麓中段的輪檯地區因獨特的自然地理位置和生態環境孕育瞭較為豐富的植物物種資源，本課題組通過野外實地調查及查閱相關文獻資料，對分佈于該區的的野生種子植物的物種多樣性及區繫地理成分進行瞭繫統地分析．結果錶明：該區共有野生種子植物876種79科338屬；科水平上，超過10種的科有17科，含種數672種，佔總種數的76.7％，區繫優勢科現象明顯；屬水平上，單種屬及寡種屬佔據優勢，有304屬，佔總屬數的89.9％；區繫地理成分多樣，區繫性質以溫帶成分為主，其中科的分佈類型有6箇類型8箇變型，溫帶成分佔非世界分佈總科數的56.4％；屬的分佈類型有13箇類型16箇變型，溫帶成分佔非世界分佈總屬數的58.2％；新疆特有種有31種，佔該區總種數的3.5％，比例相對較低．

Luntai Located in the middle of the south Tianshan Mountain in Xinjiang because its unique nat-ural geographical location and ecological environment give birth to the more abundant plant species re-sources ,based on the field investigation and consulted related literatures ,the diversity and flora of wild seed plant have systematically been analyzed .The main conclusion is as follows :There are 876 species (belonging to 79 families and 338 genera) of the flora in the Luntai region ,and ,at the families level ,there are 17 families (more than10 species) which contain 672 species accounted for 76 .7% of the total of the species in this region ;the floristic advantages division is obvious in this region ;at the genus level ,genera with one species and genera with little species domain absolute advantage w hich amount to 304 genera ac-counting for 89 .9% of the total genera ;the floristic geographical distribution types of families have six types and eight sub-types ,the temperate elements are dominant in the families floristic composition ,w hich occupy 53 .8% ;the floristic geographical distribution types of genera have 13 types and 16 sub .types ,the temperate elements occupy 56 .6% of the total genera ,there are 31 endemic species of this region of Xin-jiang w hich occupy 3 .54% of the total species of Luntai ,its proportion is relatively low .
