Kunlun is located in southern Shanxi Karakorum, the territory of towering mountains, range upon range of Diego peaks, but due to poor natural conditions, sparsely populated, less affected by the destruction of the outside world, it is essential to maintain the plateau ecosystem original state, community and vegetation types, plant kind resources are abundant. This paper, the system of seed plants morphological taxonomy, species diversity and its floristic analysis of the characteristics, and their plant resources conducted a preliminary evaluation of the basis for the area to study botany, ecological environment construction, resource use and protection of information and to provide new scientific evidence. Research shows that: China Karakoram seed plants namely genus and 47 families 205 19 659 kinds of four subspecies variants, representing the total seed plants pan-Tibetan Branch number 26.40%, the total number is 14.37% of the total number of species 7.30% . Which discovered Chinese Karakoram newly recorded two genera, newly recorded species 72 kinds five variants: Xinjiang is a newly recorded genus and new species of 19 kinds of records: Tibet a new record nine kinds of variants. The composition of the district seed plants, both in the genus or species level, secondary branches and mostly (kind of) subjects are constituted the main branch structure, both the proportion was 68.78%, 86.50%. Composition of the genus, a single species genus with few species constitute the main body of the structure, are accounted for 82.92 percent contained, but it kind of level, the variety is constituted body, 55.69% of the total number of species. Seed plants in the area, there are Chinese Karakoram endemic 11 kinds of a variant of the Xinjiang 15 endemic species and one variety, two kinds of endemic species in Tibet, China 34 kinds of endemic species and 2 varieties, Chinese Xinjiang, only distributed genus two genera, China Karakoram only distributed species and 5 species of Chinese Xinjiang distributed only kind of 136 kinds of a variant of the Chinese in Tibet is only distributed species, 9 species endemic species accounted for and distributed only area of ??32.18% of total number of species, the ratio is not high. Area Floristic composition of the seed variety, namely 10 and 15 distribution pattern variants, with obvious temperate, north temperate and variations thereof, which accounted for 73.48% is the number of the area and the Mediterranean, Central Asia, West Asia relatively more exchanges with Asian exchanges fewer tropical elements have infiltrated the area. Compared with the neighboring region, the area with the Chinese Pamirs is most closely related, the highest similarity coefficient, the section level, genus, species level reached 77.97%, 58.57%, 38.22%. Hemicryptophyte life form, which accounted for 75.11% the number of species. Seed the area is rich in plant resources, and many medicinal plants, forage, ornamental, grease, food, fragrant, nectar, wind and sand, and soil and water conservation and other aspects of great value.
