The sixteen plants are firstly divided into six types according to evaluation grades and subject function statistical method:the first type is Cajanus cajan and Crotalaria mucronata,the best adaptability ,which can be used pioneer plant or constructive species; the second type is Cynodon dactylon,the better adaptability, which can be used constructive species ;the third type is Eragrostis curvula, Paspalam notatum,which can be used constructive species on rotten rock slope ; the forth type is kummerowia striata,Lotus corniculatus and Vitex negundo.The adaptability is centered,and can be used protection species and auxiliary species;the fifth type is Robinia pseudoacacia,Eremochloa ophiuroides,Vitex negundo,Lespedeza formosa,Leucaena leucocephala,Desmodium sequax, Rhus chinne- nsis,which can't be plant singly and be used accessory species;the sixth is Trifolium repens,which can be used pioneer plant.

Basesd on the precipitation difference in Tsaidam Basin of Qinghai Province, three sampling areas, including Geremu, Delinghan and Doulan, were selected, and then three sapmling plots in each sampling area were selected to study the characteristics of plant community which dominated by Ceratoides lateens, Nitraria tangutorum, Tamarix chinensis, Kalidium gracile, Haloxylon ammodendron and Salsola arbuscula respectively. At the same time, the morphological and physiological features of above-mentioned 6 species were measured for probing their drought tolerance. By using the subordinative function method, grey correlative degree analyse and no-weight index comprehensive evaluation method, their drought tolerance were compared as well. The results were showed as follows: The main xeric vegetation types in the desert steppe of Tsaidam Basin were Nitraria tangutorum community, Tamarix chinensis community, Haloxylon ammodendron community, Kalidium gracile+Salsola arbuscula community, Ceratoides lateens+ Haloxylon ammodendron+Kalidium gracile community.
根据青海省柴达木盆地不同地区历年降水量差异,在研究区内选择格尔木、德令哈、都兰3个采样区,每个样区内确定3个采样点(表示为D11、D12、D13、D21、D22、D23、D31、D32、D33),以样区内唐古特白刺、甘蒙柽柳、梭梭、木本猪毛菜、里海盐爪爪、驼绒藜等6种主要植物为研究对象,通过调查采样地区群落特征,观测植物形态解剖特征,测定植物脯氨酸、可溶性糖、叶绿素、超氧化物歧化酶、过氧化物酶和过氧化氢酶等生理指标,研究了柴达木盆地6种植物抗旱生理特性及抗旱特性,用模糊数学隶属函数法、灰色关联分析和非加权指数评价法分别对6种植物的各个抗旱性指标进行了综合评价。

Although not quite as permanent as perennials, many biennials re-seed themselves, becoming comparable in performance to perennials. Biennial seeds that are planted one year will not flower until the following year. Foxglove, Hollyhock and Iceland poppy are biennials. Many people think of Hollyhock as a perennial as it self sows easily.
虽然没有那么长期稳定,很多两年生植物能够自我繁殖生长,这个是能够跟多年生植物相提并论的地方,两年生植物的种子在第一年播种种植之后并不会开花直到下一年,毛地黄、蜀葵和冰岛罂粟是两年生植物,许多人把把蜀葵当作多年生植物,因为他自我繁殖非常容易。

For some kinds of vegetables and pasturages, the contents of some heavy metals surpass the relevant quality standards, so when some crops were planted on the substrates, the uneatable species should be selected preferably and if some kinds of vegetables and pasturages must be adopted, the output could not be provided to mankind and also not be used in farming, in order to avoid harming peoples'health.5 The expediency evaluation model of pioneer plant on substrates was established and some plants were studied. The results show that the expediency evaluation of pioneer plants were respectively that clover was expedient to substrate 1, juniper, cotton and fescue were expedient to substrate 2 and juniper, annual bluegrass, fescue, cotton and clover were expedient to substrate 3.6 Some indexes to evaluate the capability of the phytoremediation on heavy metals and the comprehension about hyperaccumulator were put forward.
有多种植物的重金属含量超过了相应的国家标准,因此在基质上种植植物时,尽量选择非食用性植物品种,即使种植了蔬菜和牧草等植物,也不应将收获后的产品供人类食用或用于畜牧生产,以免危害人体健康。5建立和研究了复垦基质先锋植物的适宜性评价模型,结果表明,不同基质中适宜的先锋植物分别如下:基质1为苜蓿,基质2为桧柏、棉花和高羊茅,基质3为桧柏、早熟禾、高羊茅、棉花和苜蓿。6探讨了评价重金属元素植物修复能力的指标体系和"超富集植物"的概念。

In order to identify plants better, the identification of the plants is more and more important, along with it, plants taxonomy is brought, the taxonomy of plants researches classification of all plant species, the relative between different species and the nature system of vegetable kingdom.
为了能更好的运用植物与识别植物,对植物的分类与识别,越来越体现出其重要性。因此产生了植物分类学的说法,植物分类学是研究植物类群的分类、探索植物间的亲缘关系和阐明植物界自然系统得科学。

Therefore, we selected common species of Ranunculaceae. comparative primordial plants in Alpine Meadow at Eastern QinghaiTibetan Plateau, and studied the reproductive strategies, such as reproductive allocation, especially sex allocation, to understand how the plants adapt the environmental conditions. The results showed:(1) At higher altitude, the self-incompatible plant, such as Trollius ranunculoides tended to become limited by pollination rather than by nutrient availability, while the self-compatible plants, such as Anemone rivularis and A. obtusiloba seemed not to be limited by pollen availability, which suggested that ability of self pollination for alpine plants may be a mechanism of reproductive assurance.(2) Influences induced by high altitude on the reproduction of these species occurred on different reproductive characters, which suggest species-specific adaptive strategies. The influences are dependent on plant size to some extent.
因此,我们选择在青藏高原东部的高寒草甸,以比较原始的植物类群—毛茛科植物为研究对象,选择一些常见种探讨其繁殖对策,如繁殖分配和性分配问题,试图揭示这些植物如何适应环境条件,最后的结果表明: 1高寒草甸高海拔区,自交植物(如小花草玉梅A.rivularis和钝裂银莲花A.obtusiloba)的繁殖不受花粉限制,而完全异交植物(毛茛状金莲花T.ranunculoides)的繁殖受花粉限制,表明高海拔地区植物的白花授粉能力可能是一种繁殖保障机制,能够避免恶劣环境对植物有性繁殖的不利影响; 2海拔高度对植物的影响因种而异,不同的物种受影响的繁殖性状不同,即使同属亲缘种间也存在差异,表明不同物种对相似环境压力的适应对策不同;而且,海拔高度对植物的影响在一定程度上依赖于植物个体大小,说明植物通过调整其个体大小与繁殖性状的关系来适应环境梯度的变化; 3植物花期和果期的繁殖分配并不完全随海拔升高而减小(只有小花草玉梅的果期RA随海拔升高而减小30%),与Iwasa和Cohen的预测不完全一致(他们认为繁殖分配随生长季缩短而减小)。

对温度的响应(E2)植物与水(D2)温度与物种分布(E3)动物与水(D3)生态系统格局(S1) High temperatures may lead to enzyme inactivation or the unbalancing of components of metabolism; for example, in plants, respiration may proceed faster than photosynthesis, leading to death, however, the most frequent effect of high temperature on ectotherms is dehydration.

In wetter habitats, hygromeso-and hygrophytes were more abundant and accounted for the majority of aboveground biomass, whereas xero-and mesoxerophytes became more important in dryer habitats; the mean δ〓C values of xerophytes was the highest, and those of meso-, hygromeso-and hygrophytes the lowest; From xerophytes to hygrophytes, their proline content markedly increased.
