生态学者

To meet the needs for scientific, technological and socio-economic development in China, we proposed the four areas that the Chinese scientists should focus their study of global change and terrestrial ecosystems in future, including:(1) Metabolism and coupling mechanism of key life elements in terrestrial ecosystems in China;(2) Implications of terrestrial ecosystems in areas sensitive to global change and in important transects on global change;(3) Interactions between biogeochemical cycle of C, N, P, S in China and global change; and (4) Development of regional dynamic vegetation model which meets the actual needs of China.

中国学者在全球变化与陆地生态系统研究领域也开展了许多工作并取得了重要成绩。按照我国科学技术和社会经济发展的需求，本文提出了未来我国在该领域的研究重点，包括（1）中国陆地生态系统重要生命元素的代谢及其耦合机制研究；（2）全球变化敏感区域或重要样带上陆地生态系统对全球变化的影响研究；（3）我国的C、N、P、S生物地球化学循环与全球变化的关系研究；（4）发展中国特色的区域植被动态模型。

"Is your biology teacher an ecologist ?"

"你们生物学老师是个生态学者吗？"

But it is the legacy of Wordsworth, who became a tourist attraction himself, as Romantic, ecologist, guidebook writer, landscape gardener (of particular appeal to Mr Thompson, a landscape architect) and arbiter of taste that continues to inspire and provoke controversy.

华兹华斯如今已经是这片地区吸引游人的原因之人，他是一位浪漫派诗人，是生态学者，旅游指南书的作者，同时也是一位风景园林师（他作为风景园林师这一方面尤其吸引身为造园师的作者汤普森）。

Ecologists assign every organism in an ecosystem to a feeding level ,or trophic level,depending on its source of food or nutrients.

生态学者认为每个生物在生态系中的哺食阶层和营养阶层它所依靠的来源是食物和营养物。

Although many scholars had attempted to define it, the typical definitions of niche are Grinnell's space niche, Elton's functional niche and Hutchinson's hypervolume niche; Niche metrics include niche breadth, niche overlapping, niche volume and niche dimension, among which niche breadth and niche overlapping are two important indexes that can be used to characterize a species niche and the relationships between species niches.

许多学者都试图给生态位下定义，但最具代表性的当推Grinnell、Elton和Hutchinson分别给出的&空间生态位&、&功能生态位&和&多维超体积生态位&定义；生态位测度包括生态位宽度、生态位重叠、生态位体积及生态位维数等，其中生态位宽度和生态位重叠是描述一个物种的生态位以及物种生态位间关系的重要指标。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.

采用曲线坐标系下压力与速度耦合的SIMPLER算法，数值研究了周期性渐扩渐缩波纹通道内脉动流动与换热情况，流动Re数的范围为10~1000，Pr数为0.7。
