Studies On Leguminosae On The Pamirs Of China

The China Pamirs plateau located in the southwest of Xinjiang is a mountain joint formed by Tianshan Mountain, Kunlun Mountain, Kelakunlun Mountain and XingDuku Mountain. It' s position is remote and natural environment is bad.This article has conducted the comparison system shape taxonomy research to this local Leguminous plant, and has carried on the analysis to its species diversity, the flora and so on, has made the preliminary appraisal to its resources use. The research indicated that:â…  .In the Pamirs of China Leguminosae plant altogether has 14G 74Sp, accounts for 29.8% and 18.5% oftotal genera and species of Xinjiang Leguminosae. The Chinese Pamir new record is 2 G 9 Sp, Xinjiang new record is 6 species. It increases 2 G 9 Sp compared to old literature materials.â…¡ .In the Pamirs of China Leguminosae plant areal-types are distributed to 7 areal-types and 3 subtypes. The temperate is dominating ingredient, account for 50.02% of all Leguminosae, without the tropics distribution and the Chinese unique distribution.â…¢.There are 2 multiplicate genus 51 species, accounts for 14.3% and 68.9% of total genera and species of Leguminosae plant in the Pamirs of China which are Astragalus L. and Oxytropis DC.It has 6 widowed 17 species and 6 autogenus 6 species. Among them, the Chinese Pamir unique distribution plants is 7 kinds, the Chinese Xinjiang unique distribution plants is 23 kinds, the Xinjiang endemic species is 2 kinds.â…£ .In the Pamirs of China of Leguminosae plant life forms, hemicryptophyte plant is dominant as high as 73%. The perennial herb occupies the dominant position.But phanerophyte, chamaephytes and therophyte are few. The ecotype is primarily the mesophyte, the xerophyte are few, the humidogene and the aquatic plant do not have nearly.â…¤ .This region Leguminosae plant resources are quite rich.Many kinds of Leguminosae plants have the important value for edible, raiseing, medicinal purposes and watching aspects and so on.
