Examples
- 14 species are edible plants , 37 species are medicinal plants , 11 species are ornamental plants and31 species are feeding plants , the major types of halophytic vegetation in hebei province include ptenothalophyta such as tamarix chinensis brush and siberian brush , and littoral halophytic vegetation such as succulent vegetation , poion , chomophyte and etc . epidermal cell exosporium of tamarix chinensis blade is papillous and capillaceous ; stoma and salt - secreting gland are under the epidermis ; differentiation level of mesophyll tissue is rather high ; porder camber is obvious ; and mechanical tissue is developed
河北省盐生植物的经济价值较高，其中可食用的盐生植物共计14种，可药用的盐生植物37种，可饲用的盐生植物31种，具有观赏价值的盐生植物11种，可以作为纤维植物计约9种。河北省主要盐生植被类型有柽柳灌丛、西伯利亚白刺灌丛等落叶灌丛和肉质型、禾草型、杂类草型盐尘植被等滨海盐生植被。 - The results indicated that as the intensity of sward cleavage increased , elymus nutans and other plants that had high requirements in soil aeration and resource space presented an increased competitive edge and the species that had low requirements in soil aeration and resource space presented an opposite picture ; low - intensity sward cleavage could help increase species diversity to a certain extent , but the diversity index appeared to decline as a whole as the cleavage intensity increased ; the effects of sward cleavage on functional groups of the vegetations showed in such manner as e . nutans - represented grasses increased in their composition with the intensity of sward cleavage raised , and sedges and forbs decreased in their compositions with the intensity of sward cleavage raised ; sward cleavage showed a significant improving effect on primary productivity of the meadows and was capable of increasing the proportion of quality - grass biomass to the total plant biomass ; sward cleavage could be independently employed as an effective measure to rehabilitate and improve alpine - meadow grasslands and thus played a basic and key role in the technical combination aiming at establishing hay fields characterized by e . nutans
结果表明：垂穗披碱草等对土壤通透性和资源空间要求较高的物种，竞争力随划破强度的增加而上升，而对土壤通透性和资源空间要求相对较低的物种则相反；轻度划破干扰对提高物种丰富度具有一定的促进作用，但多样性指数则总体上表现为随划破强度的增加而呈下降的趋势；划破干扰对植被功能群的影响表现为以垂穗披碱草为代表的禾草类组分随干扰强度的增加而显著上升，莎草类和杂类草组分随干扰强度的增加而显著下降；划破干扰对草地初级生产力的提升具有显著的促进作用，且可显著增加植物总量中优质牧草的比重；划破干扰可独立作为高寒草甸类草地恢复与改良的有效措施，在定向培育垂穗披碱草型割草场的技术组合中具有核心和基础性的地位。
