Karakoram Mountains in West Kunlun Mountains northwest Himalayas, the entire mountain northwest - southeast direction, China and Kashmir Jieshan by several horizontal rift basin segmentation, mountain intermittently from the Pamirs the southeast has been extended to the Qiangtang plateau. The Chinese Karakoram mainly including China's Xinjiang Taxkorgan County southwest Har its Chur river on both sides of its southern Yarkand River south region, Yecheng, Pishan, Wada three counties southwest of State Road 219 and Ali Region Day soil County, northwest of the high mountain, about 1100km, a width of 100-220km, an average altitude of about 5000m, unique in its main peak area average altitude of nearly 6000m, vegetation types, alpine desert and alpine meadows advantage with. This article in this region from the petal flowers (except Cruciferae, Leguminosae) plant the morphological taxonomy study, based on analysis of species diversity, including the families and genera composition, plant life form and flora geography compositional characteristics and preliminary classified and evaluation of its resources. Provide useful scientific basis for the construction of the ecological environment of the plants in the area, the conservation of species diversity, the use of plant resources. The study showed that: the Chinese Karakoram off petal flowers (except Cruciferae, Leguminosae) plant total of 22 families, 75 genera and 181 kinds of 10 variants, pan-Tibetan Plateau 20.75% of the total family number of isolated flower petals class plant, with a total genera, 14.48%, 5.24% of the total number of species. The newly discovered the Chinese Karakoram new recorded genus 2 case, the Chinese Karakoram new recorded species of the 24 species and 3 varieties Xinjiang newly recorded species of the 10 species and 2 varieties, Tibet newly recorded species of the species and one variety. Area away from the the flower petals class (except Cruciferae, Leguminosae) plant family composition, middle-genus families and oligonucleotides are subjects constitute the main body of the Branch structure, accounting for 85.33% of the genera contained species level , the Medium Division as the main body the contained species accounted for 80.11%. The composition of the genus, the single species and few species of genus constitute the main body of the metal structure accounted for 92.00% of the genera contained, but the species level, oligonucleotide species and a variety of case constitute the main, 76.80% of the total number of species . Area away from the the flower petals class (except Cruciferae, Leguminosae) plants are endemic to the phenomenon is not obviously belongs to China Karakoram endemic only 1 species, accounting for 0.55%. Area away from the flower petals class (except Cruciferae, Leguminosae) plant life form to Hemicryptophytes-based, 120, 66.30 percent of the total number of species, respectively, accounting for 12.71%, followed by the annual herb, phanerophytes and 12.15%, the the chamaephyte geophyte accounted for only 6.08% and 2.76%. Area (except Cruciferae, Leguminosae) away from the flap flower flora and diverse geographical elements, a total of seven distribution type and 10 variant. Obvious temperate nature of the area north temperate distribution of its variants. 55.38% of the total in the case of relatively more exchanges with the Mediterranean, West Asia, Central Asia, and the few exchanges with East Asia, and tropical. Compared with neighboring regions, Karakoram and adjacent areas away from the flower petals class (except Cruciferae, Leguminosae) flora, both have different degrees of contact, which most closely with Chinese Pamirs, similar the coefficient of the highest scientific level, genus and species level, 80.77%, 72.45% and 35.81%, respectively. Secondly, similarity, followed by Afghanistan, Eastern Himalayas and the Tibetan Plateau, the family level similarity coefficient were 34.43%, 21.13%, 20.75%, the genus level similarity coefficient of 19.71%, 13.36%, 13.38%, indicating that the closer contact the Division level and genus level; species similarity lower coefficient of approximately 4.10%, 0.02%, 4.10%, indicating that the alternative between these regions belong to the same plant species distribution significantly. Area plant resources away from the the flower petals class (except Cruciferae, Leguminosae) is relatively rich, many of the plants with the important value of ornamental, medicinal, forage, grease.
