查询词典 meadow clover

Higher Ca distributed in bulliformcell than in mesophyll cell and bundle sheath cell of dune reed, higher Mg distributedin mesophyll cell and higher K, Na and Cl distributed in sheath cell HigherNa and Mg distributed in mesophyll than in bulliform cell and bundle sheathcell of light salt meadow reed, and higher K, Ca and Cl distributed in itsbundle sheath cell. Higher Na and Mg distributed in bulliform cell than in mesophyllcell and bundle sheath cell of heavy salt meadow reed, higher K, Ca and Cl distributedin its mesophyll cell. This paper discussed the distribution conditions of theabove five ions in leaf cell of the four reed ecotypes and the meaning ofphysiological adaptation to habitat in detail.

From May to October 2004, the seasonal changes of K, Ca, and Mg contents and accumulation in Calamagrostis angustifolia, the dominant species in the typical meadow anti marsh meadow communities of Sanjiang Plain, were studied.

2004年5-10月，对三江平原典型小叶章草甸和小叶章－苔草沼泽化草甸群落优势植物小叶章的K、Ca、Mg含量与累积的季节变化进行了研究。

Coniferous forest was further reduced,whereas Cyperaceae meadow and/or swamp meadow expanded ,indicating a drop in temperature.

With the deflected succession of aquatic ecotype plant functional group,the dominance of mesophytes and xerophytes increased,while the dominance of aquatic and hygric plants decreased. However,there are only planting crops in the reclaimed wetland. In the composition of plant biotype functional group,the hydrophytes reduced quickly with the deflected succession and the dominance of perennial herbs is mostly marked,and there are only annual herbs in reclaimed wetland. Compared with primary swamp,the species diversity index of meadow is the highest,the swampy meadow follows,and the reclaimed wetland is the lowest.

植物的水分生态型功能群组成随湿地的逆行演替，水生、湿生类植物功能群的优势度不断减少，中生、旱生类植物功能群的优势度逐步增加，而在垦后湿地只有农作物；植物生活型功能群组成随湿地的逆行演替，水生草本迅速减少，陆生多年生草本增加占据优势，而在垦后湿地均为一年生草本；湿地植物物种丰富度、多样性指数由原生沼泽、沼泽化草甸到草甸依次增加，草甸为最大值，而垦后湿地则最低。

This results indicated that peashrub shrubland created a favorable N condition for its invading the meadow and being invaded by birch forest, and played a important role in altering the successional direction of meadow→peashrub shrub land →birch forest.

尽管箭叶锦鸡儿灌丛植物叶片与凋落物中全N、全P浓度在大多数取样点上都低于硕桦，但表层土中全N浓度高于硕桦和草甸，且其土壤有机质的供氮能力以及维持氮素能力都高于硕桦林和草甸，表明，锦鸡儿灌丛为侵入草甸和硕桦入侵提供了良好的养分条件，在该演替序列的发展过程中起了一定的推动作用。

The objectives of the study were to: 1 reveal the responses of vegetation and soil to degradation by investigating community characteristics and soil physic-chemical properties; 2 quantify the contributions of human factors and natural factors and the relationship among the factors by analyzing the variation of each factor in past decades; 3 understand the succession of fenced undegraded meadow, artificial pasture, semi-artificial pasture and degraded meadow, and to 4 provide suggestions for restoration and rehabilitation of the degraded rangeland in the region.

本项研究旨在通过对黄河源区退化高寒草甸的植物群落特征和土壤特征调查，揭示植物和土壤养分对土地退化的响应；对源区人口及牲畜数量和国内生产总值，气候变化特点等因子的分析，量化人为干扰因子和自然因子的贡献率以及各因子之间的数量关系；以及对草地退化驱动力分析以及原生草地植被封育、人工草地、半人工草地的自然演替变化规律的研究，为高寒草甸退化草地恢复与重建提供科学依据。

That was a gold meadow beside the valley of Xia Te river, we walked along the river, strong sunshine sprinkled like fleck at the small path through dense pine trees, there were some unknown wild flowers in the meadow, there were some moldered old trees falling down roadside, the bare roots seemed telling the waste of time and history.

沿夏特河谷边金黄色的草甸循溪而上，太阳透过密密的松林，将烈烈的光斑斑驳驳的撒在小径上，空地上零星的开着不知名的野花，时不时能见到早已腐朽的老树横倒在路边，裸露的根像在诉说着那万年的蹉跎与沧桑。

Additionally, species with larger plasticity in biomass allocation and relative growth rate also showed higher seedling survival rate.7 All these suggested that higher light availability in grazed disturbed meadow community favor seedling recruitment for these familiar forbs component species, but bottom shade in fertilized meadow community restrain seedling recruitment for these species.

在变化的微生境下，具有较小生长可塑性的物种具有相对较大的幼苗存活率；而生物量、株高可塑性和平均可塑性较高的物种具有相对较大的幼苗越冬存活率；具有较大的生物量分配和相对生长率可塑性的物种幼苗具有相对较大的存活率。7放牧干扰下的高光照微生境有利于这些草甸常见组分种实生幼苗的更新补充，而施肥后草甸群落冠层底部的低光生境不利于这些物种的更新补充。
