Four leguminous forage species were introduced to the deteriorated natural alpine Kobresia grassland in the south of Gansu to determine their effect on promoting grassland productivity. The species tested were Onobrychis viciaefolia, Trifolium pratense, T. repens and Medicago sativa. It was shown that O. viciaefolia, T. pratense and M. sativa can grow normally under the local conditions, and their growth was consistent with the Logistic Growth Model, in which the inflexion points on the growth...

Four leguminous forage species were introduced to the deteriorated natural alpine Kobresia grassland in the south of Gansu to determine their effect on promoting grassland productivity. The species tested were Onobrychis viciaefolia, Trifolium pratense, T. repens and Medicago sativa. It was shown that O. viciaefolia, T. pratense and M. sativa can grow normally under the local conditions, and their growth was consistent with the Logistic Growth Model, in which the inflexion points on the growth curves of the 3 species took place during JuneJuly when the maximum of combined waterheat values was attained. The highest forage yield was obtained from O. viciaefolia: 4 247.33 kg aboveground dry matter per hectare, containing 480.37 kg crude protein, 45.45 kg calcium and 5.82 kg phosphorus.

There has been a rapidly increasing interest in the effects of species richness on ecosystem productivity. In order to search for a general species richness_productivity pattern and find the mechanisms underlying the pattern, ecologists have undertaken intensive empirical studies. Due to different ecological contexts (such as characteristics of surrounding environment, spatial and temporal scales of investigation) in a variety of experimental studies, positive, negative, and non_existent diversity_productivity relationships have been observed. The species richness_productivity connection still remains unclear. Experimental manipulated studies have generated a considerable amount of criticism based upon their experimental methodology, analysis, and general conclusions. In this paper, we use data collected from a typical natural alpine meadow to explore the general species richness_ productivity pattern. Over a two_year period, we recorded the total number of species present, and estimated and measured percent coverage of each species and its aboveground biomass in 80 permanent plots three times in each growing season. Ecosystem productivity was estimated as aboveground biomass. We tested whether the species richness_productivity relationship is monotonic and whether the relationship varies as the spatial and temporal scales change. Our results showed that:1)There is an overall log_linear increase in species richness_productivity pattern; it actually reflected an overall species richness_productivity pattern of alpine meadow plant community in the interaction of spatial and temporal scales on enlarged temporal and spatial scales. 2)The species richness_productivity relationships change with temporal and spatial scales, but the influence of spatial scales on the relationship is more significant than that of temporal scales. This may be due to the short growth season. Based on the above results, we suggest that the differences in temporal and spatial scales may cause non_consistent species richness_productivity relationship in varieties of experimental studies.

以物种组成较为复杂的青藏高原东部地区典型高寒草甸植物群落为背景 ,从不同的时间和空间尺度水平研究了植物群落中物种丰富度与生产力 (地上部生物量 )关系的基本模式。结果表明 :1)总体而言 ,高寒草甸植物群落中物种丰富度与生产力的关系呈对数线性增加关系 ,这实际上是空间和时间尺度放大时在时间和空间尺度的相互作用下高寒草甸植物群落中物种丰富度与生产力关系的一种总体模式 ;2 )随着研究的时间和空间尺度的改变 ,物种丰富度与生产力的关系会发生一些相应的变化 ,但空间尺度比时间尺度对物种丰富度与生产力的关系造成的影响更为显著 ,这可能与高寒草甸植物群落的生长季短有关。上述结果揭示 :时间和空间尺度的不同可能是造成许多试验研究得不到一个统一的物种丰富度 生产力关系模式的主要原因。

A study was conducted at the Sanjiao City Sheep Breeding Grassland Area of the Qinghai Province, which is located on natural alpine grassland on the north bank of Qinghai Lake. Nitrogen and phosphorous chemical fertilizers were applied to some of the alpine steppe, and area permanently enclosed in fences and that not enclosed was compared, to find the best approach to restore degraded grassland. After application of fertilizer, the importance value of excellent pasture showed an increasing trend,...

A study was conducted at the Sanjiao City Sheep Breeding Grassland Area of the Qinghai Province, which is located on natural alpine grassland on the north bank of Qinghai Lake. Nitrogen and phosphorous chemical fertilizers were applied to some of the alpine steppe, and area permanently enclosed in fences and that not enclosed was compared, to find the best approach to restore degraded grassland. After application of fertilizer, the importance value of excellent pasture showed an increasing trend, and the increase was greater within the fenced area than without. The natural alpine steppe showed the same trend with greater importance value of excellent pasture within fenced areas than that without. Man-imposed control strategies showed significant effects on the species richness of the plant communities. Plant communities with chemical fertilizer applied showed significant loss of species, and the number of species within the fenced area increased. Thus, it can be seen that both chemical fertilizer application and fencing can affect the species of plant communities.

本研究选择青海湖北岸青海省三角城种羊场地区的天然高寒草原为研究对象,对多年围栏的样地,在围栏内外采用施N、P肥作为调控措施与围栏内外的天然草原作对照,旨在寻求退化草地恢复的最佳途径。结果表明,施肥后优良牧草重要值呈增大趋势,且围栏内比围栏外增大程度高;对照区优良牧草的重要值亦是围栏内较围栏外高;人为调控措施对群落物种丰富度有显著的影响,施肥群落的植物种类显著降低;围栏内物种数增高;施肥和围栏封育都能影响群落的植物种类。
