三棱

Chongming Dongtan wetland plant is composed by mariqueter grass scirpus community,reed communities and Spartina alterniflora communities.The resource of bird is rich,there are records of up to 136 kinds of water birds.

崇明东滩湿地的植被群落主要由海三棱藨草群落、芦苇群落和互花米草群落等组成；鸟类资源丰富，有记录的水鸟达136种；底栖生物大型底栖动物45种，隶属于5门7纲。

The same life form, vegetative reproduction strategy and similar age structure of Scirpus planiculmis or Carex kirganica were due to the long time convergent adaptation.

紧穗三棱草和长秆苔草相同的生活型、相似的种群年龄结构和无性繁殖方式是对湿地生境长期趋同适应产生的结果。

Based on the analysis of the contents of Cu, Pb, Mn, Zn, and Cr in the rhizosphere sediments of Phragmites australis and Scirpus mariqueter at tidal flat in Changjiang Estuary, the following conclusions can be drawn.

长江口滨岸潮滩芦苇与海三棱草根系、茎叶以及根际沉积物中Cu、Pb、Mn、Zn、Cr的含量分析发现，Cu、Pb、Zn、Cr在根系中的含量较高，而Mn在茎叶中的含量达到总量的55%以上。

The results of the examine indicated that Scirpus mariqueter disturbed the phosphorous distribution by drawing phosphate from sediments and microbial degradation which formed the horizontal and vertical concentrational grads.

实验结果表明，海三棱藨草通过根系对磷的吸收和自身有机质降解，在沉积物里形成了水平的和垂直的浓度梯度，干扰了磷的正常累积和迁移。

The content of Mn in stems and leaves can account for up to 55%. Scirpus mariqueter can accumulate more heavy metals than Phragmites australis. And the heavy metal contents have se...

植物体内重金属含量一般在冬季富集；芦苇根际沉积物中重金属的含量秋季较低，冬季富集，而海三棱草根际沉积物中Cu、Pb、Mn均在秋季含量较高，Zn、Cr冬季含量最高。

Based on the observation about the ramets characters of predominant clonal rhizome plants from wetland, their modular structure, reproductive allocation and population dynamics were measured and results indicate that:(1) There are 2 or 3 age classes of ramets and 3 types of tubers of Scirpus planiculmis population in terms of four times observation in three years.

对湿地优势根茎植物种群分株构件的年龄结构、构件性状、生殖分配及种群数量动态观测结果表明：(1)紧穗三棱草种群分株3年4次观测有2～3个龄级，球状根茎可划分为3个类型。

The mains results are as follows: 1,In Scirpus speices, the allocation to sexual reproductive ramets and vegetative ramets varied with environmental conditoin and life history stages. This makes the species adapt to tidal flat stresses and utilize heterogenetiously distributed resources.

主要结果有： 1，海三棱麃草中，随年龄增加和生境改变，植物的有性繁殖和营养繁殖构件的生长速率，以及球茎贮存物质的比例发生改变，这种特性使物种适应高胁迫下的潮滩生境，同时提高了植物体利用异质性资源的能力。

We in this project studied module dynamics, physiological integration between modules, and the relationship between module dynamics and environmental change including physical and biological interaction for perennial herb Scirpus mariqueter, annual cotton, and tree species of Querucus fabri.

本项目分别以多年生草本克隆植物海三棱麃草，一年生农作物棉花和多年生高大乔木栎树为研究对象，研究了这几种不同构件特征集合体的构件动态、构件间的生理整合及其对环境变化的响应、构件动态与环境因子的变化关系，构件动态与动物侵食的关系等。

At middle and lower marshes of the northern part of Dongtan, the invasive Spartina alterniflora was a dominant plant type by replacing the native Scirpus mariqueter .

在北部滩涂的中潮区和低潮区，互花米草已经替代海三棱藨草成为优势群落，而且其植株密度和地上生物量均高于同科植物芦苇，其竞争优势十分明显。

The effect of Scirpus mariqueter on phosphorous distribution in intertidal sediments was examined by measuring the phosphorous concentration in nearroot, meanroot and farroot sediments at different depths in three cores, with application of the theory of rhizospherical microbe.

以海三棱藨草为例，运用实验模拟的方法，通过根际、近根和远根沉积物的对比分析，运用根际微生物作用理论，研究了大型植物对潮滩沉积物磷分布及迁移转化的影响。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
