Current research survey on ALB,their ecological role and biomass detection methods were emphatically summarized.

介绍了溶藻细菌的研究概况，重点对溶藻细菌的生态学作用及其生物量的检测方法进行了综述。

The composition and biomass of them were studied,and the ecological distribution sections of every alga were summarized.

分析了各地区春季不同月份藻类的种群结构和平均生物量变化，总结了各藻的生态分布区域。

The green tide formed by the large scale proliferation of Ulvaceae alga has become one of global ecological phenomena.

由石莼科绿藻大量增殖形成的绿潮已成为全球常态发生的生态现象之一。

The definition, inductive factors, ecological effects and treatments of harmful alga bloom are discussed in this paper.

论述了有害藻华的含义、成因及其生态学影响，总结了目前有害藻华的治理方法。

The studies have shown that the reduction of grass, wetlands, waters and rapidly increase in saline alkali soil are the extrusive performance of the ecological environment deterioration in Songnen plain hinterland.

研究显示，草地、湿地、水域的减少和盐碱地的迅速增加是松嫩平原腹地生态环境恶化的突出表现。

The saline alkali soil in Jilin province was formed under semiarid and semi moist weather which was distributed in bai cheng region. And the western grassland is the important animal husbandry base in Jilin province. So as far as the development of western animal husbandry and the goal of becoming an ecological province is concerned, it is of important significance that people turn the saline alkali soil into arable soil.

吉林省内的盐碱土，是在半湿润半干旱气候条件下形成的内陆型盐碱土，主要分布于西部的白城地区，而西部草原又是重要的牧业生产基地，因此，将这些盐碱化的土壤转变为可以耕种的土壤，对西部牧业的发展和实现生态省建设的目标来说，具有重大的意义。

Third, ecological management must be linked to poverty alleviation and wealth creation.

第三，生态管理必须与减轻贫困和创造财富。

The leaf modules of different age tillers of grey green and yellow green ecotypes had the same regulation of allometry and biomass accumulation at the reproductive stage in the Songnen Plain. All quantity indices, such as biomass, length and width of leaf and regulation of biomass accumulation, were different between the two habitats of the same ecotype and between the two ecotypes at the same habitat. The results showed both ecotypes had adapted to their corresponding habitat and obviously had ecological plasticity.

在松嫩平原的繁殖期，灰绿型和黄绿型羊草不同龄级分蘖株叶构件具有相同的异速生长和生物量积累规律。2个生态型羊草叶构件的生物量、叶长、叶宽、生长和生物量积累规律等在相同生态型不同生境之间，相同生境不同生态型之间，以及不同龄级分蘖株之间的各个数量指标均有一些差异，但变化幅度不大，是2个生态型对其所在生境产生的相应适应性反应，具有明显的生态可塑性。

Variances were found among the varying amplitudes of the individual ecological field gradients of Alsophila spinulosa in different sites. The maximal gradient values and effect distances of the maximal gradients also varied.

不同地段的桫椤种群个体场梯度大小变化幅度不同，最大场梯度值以及出现最大场梯度时的作用距离亦不相同。

With the increment of the distances to field source plants, the individual ecological field gradients of Alsophila spinulosa increased gradually at first to the maximal values, then decreased gradually and converged at zero at last. The varying form fitted Rayleigh distribution.

随着与场源距离的增加，桫椤个体生态场梯度先逐渐升高，达到最大值后又逐渐降低并收敛于零，其变化形式符合Rayleigh分布。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
