Evaluation Of Germplasm Resources Of Wild Woody Plants In Hami

For the characteristics of woody plant germplasm resources in Hami area to conduct a comprehensive assessment value of development and utilization,this paper selected 138 kinds in the Hami area,strong adaptability,wide distribution,strong local characteristics and has a high potential for the development of wild woody plants as the research object.First carries on the analysis and detailed classification of diversity value of plant resources,divided into commercial value,service value and genetic value,and then uses AHP to three value types of plant resources were qualitative and quantitative analysis and evaluation value,according to the level of development and utilization of the value of their is divided into several levels.Finally,the existing protection of late Wild Woody Plants Germplasm Resources Problems and solutions are discussed.The main results are as follows:The analysis of the value diversity of wild woody plant resources shows that the commercial value is the most abundant.After the business value assessment results,the highest grade commercial value species there were 8 species,including Artemisia Artemisia sphaerocephala,head of Elaeagnus oxycarpa Elaeagnus oxycarpa,Populus euphratica,Populus euphratica Populus tremula Populus tremula,Lonicera caerulea,Altai honeysuckle Caragana leucophloea Caragana leucophloea,Lonicera hispida and Lonicera hispida Clematis in Siberia Clematis sibirica.The second class tree with higher value has 15 kinds of plants,the average class III tree is of 17 kinds,and there are 15 kinds of plants with relatively small numbers of the fourth class trees.The Hami region has rich resources of wild woody plants,mostly located in the eastern Tianshan Mountains,Hami area of the Gobi desert,plays an important role in maintaining the balance of the local ecological system,has the important value of the public.After the public value assessment results,the highest level of service value of species there were 5 species,including Tamarix hispida,Siberia: Mao Chengliu just Nitraria c.acanthophylla Nitraria sibirica,Caragana anthophylla,Halocnemum strobilaceum and Halocnemum strobilaceum tamarixlaxawilld Tamarix laxa.The second class tree with higher value has 19 kinds of plants,the average class III tree is of 8 kinds,and there are 16 kinds of plants with relatively small numbers of the fourth class trees.In addition,Hami local special germplasm resources of wild woody habitat created some cold and drought resistance,salt resistance,pest resistance,these plant resources and local treasure endangered plants constitute a valuable germplasm gene pool of rare local Hami,has high scientific value.Through scientific evaluation results,the highest level of scientific value of species there were 5 species,including: Larix sibirica,Juniperus Sabina schrenkiana,medlar Picea cylinder gymnocarposprzewalskii Juniperus sibirica,Juniperus Sabina and Siberia ephedra Juniperus Ephedra prewalskii.The second class tree with higher value has 6 kinds of plants,the average class III tree is of 6 kinds,and there are 12 kinds of plants with relatively small numbers of the fourth class trees.In addition,there are many potential values that have not yet been fully recognized and utilized,and need further development.In promoting the sustainable development of ecological civilization today,with rich commercial value of woody plants,medicinal resources such as biomass energy if you can get a correct assessment of the value of development and utilization,is a non negligible green resources for local residents.
