The resource niche width of Aneurolopidium chinense,its seasonal change and niche overlap with other main plants at different levels on the northeastern Songnen rangeland were measured and analysed. The results showed that water niche width of Aneurolepidium chinense was chiefly determined by the resource utilizing proportion by Aneurolepidium chinense;light niche width depended on the utilization intensity of light energy;nitrient niche width was chiefly influenced by the soil nitrient differences...

The resource niche width of Aneurolopidium chinense,its seasonal change and niche overlap with other main plants at different levels on the northeastern Songnen rangeland were measured and analysed. The results showed that water niche width of Aneurolepidium chinense was chiefly determined by the resource utilizing proportion by Aneurolepidium chinense;light niche width depended on the utilization intensity of light energy;nitrient niche width was chiefly influenced by the soil nitrient differences at habitat;Aneurolepidium chinense niche width has the seasonal changes; the overlap of plant populations' niches has a certain regularity with soil water and alkalization gradients.And the niche overlap is the basis of plant coexistence in this area.

计测了东北松嫩草原上羊草种群的资源生态宽度、生态位宽度季节变化,羊草与其它主要植物种群的资源生态位重叠,并在不同水平梯度上做了较深入的分析。研究表明:羊草种群水分生态位宽度主要取决于羊草的资源占据比例;光生态位宽度主要依赖于光能的利用强度;营养生态位宽度主要受生境土壤养分差异的影响;羊草生态位宽度存在着季节性变化;植物种群生态位的重叠值随土壤水分与碱化度梯度呈有规律变化,生态位重叠是该地域植物共存的基础。

In the area where this research was conducted,spring drought caused wheat to delay vegetative growth,to advance reproductive growth,to decrease heading rate and to increase degenerated ears. So the production greatly reduced. According to spring wheat's water niche suitability,the first half of May is the first damage threshold of water stress,and the period of time from the last ten days of May to the early June is the second one.

春旱使春小麦营养生长滞后,提前进入生殖生长,抽穗率降低,退化小穗的比例增加,造成大幅度减产。从春小麦的水分生态位适宜度看,五月上、中旬为水分伤害的第一个阈值点,五月下旬至六月初为水分伤害的第二个阈值点。后者是常住的。

The three water-depth niches in which Ranalisma rostratum stapf population grown were mimicked, they were called wet, emergent and submerged. The results showed that there was a great increase in plant height, root system length, internode length of pseudo-stolons, number of ramets per clone, fecundity and total mean biomass per clone for R rostratum population, in emergent compared with in wet and submerged, . In wet and emergent, sexual reproduction and vegetative reproduction both could arise normally,...

The three water-depth niches in which Ranalisma rostratum stapf population grown were mimicked, they were called wet, emergent and submerged. The results showed that there was a great increase in plant height, root system length, internode length of pseudo-stolons, number of ramets per clone, fecundity and total mean biomass per clone for R rostratum population, in emergent compared with in wet and submerged, . In wet and emergent, sexual reproduction and vegetative reproduction both could arise normally, but the former tended to be the major in wet. In submerged, the population survived only depanding on very weak vegetative reproduction, and the sexual reproduction could hardly appear. Above all, emergent was the ideal water niche of R rostratum population.

在长喙毛茛泽泻(RanalismarostratumStapf)实验田中模拟出该种群生长的3种水生态位,即湿生、挺水、沉水。结果表明:在挺水状态下,长喙毛茛泽泻种群的株高、根系长度、纤匍枝节间长度、无性小株数、生殖力、总生物量都明显高于湿生和沉水状态。有性生殖和营养繁殖在挺水和湿生条件下都能正常进行,在湿生状态下种群倾向于有性生殖。在沉水状态下,有性生殖基本不能进行,种群以微弱的营养繁殖保存。挺水状态是长喙毛茛泽泻种群理想的水生态位
