Considering high extraction rate and activity of TPS, the extracting conditions were optimized by using expectant function approach for simultaneous optimization of several variables levels, these were 0～1 temperature, 0～1 heating time, 0～0.5 ratio of tea to water and -0.95pH.

对福鼎大白茶、白毫早等7个代表性茶树品种的多糖进行分析，表明不同品种茶多糖含量，多糖的中性糖、糖醛酸、蛋白质含量以及清除·OH和O〓的能力存在明显差异，说明茶多糖特性和生物活性存在品种多样性。

In the past, studies have been concentrated on some of the pathogenic bacteria due to the diversity of oral organisms, complexity of ecological environment and limitation of research methods. Few research was involved in the change and gene expression of microbial population and role of functional protein in the matrix of dental plaques in the pathogenesis and development of disease.

由于口腔生物的多样性、生态环境的复杂性以及研究方法的局限性，以往研究大多集中于部分致病菌；对于菌群在疾病发生、发展过程中的整体性变迁及其基因表达、菌斑基质中功能性蛋白质分子作用的研究甚少。

To understand the impact of plant canopy photosynthate inputs on soil nematode communities, a large-scale tree girdling experiment was conducted in a evergreen broad-leaved forest of Ailao Mountains.

3为了解植物光合产物通过根系实现的地下资源输入对土壤生物的影响，本研究通过大规模的环割实验切断植物向地下运输光合作用产物的通道，研究了环割前后土壤微生物生物量、土壤线虫密度和多样性的变化。

In chapter one, the former mono-disciplinary studies to the karst mountain in southwest China are analyzed and summarized.

具备复杂多变的小生境和以此为基础的多样性较高的生物群落。

Results show that the two systems are very similar in mathematical structure and diversity characteristics, and both are reasonable information systems, which fit well to the same distribution models, such as power law distribution and lognormal distribution.

The small peptides always accomplish their configuration in the cell. Through molecular recognition, they show biology function, completely representing the diversity and cooperation among molecules.

功能短肽总是在细胞中完成其构象变化，通过分子水平上的识别效应，实现其生物功能，充分体现了分子内及分子间相互作用力的多样性和协同性。

In a word, according to the research of pulp wastewater treatment using pond-reed system, we discovered that the complex system can removal wastewater pollutants effectively, at the same time, the salinity of soil is dramatic decreased through wastewater washing, which bring many active results: increasing of N, P, and organic matter; enhancing of soil microbes, enzymes, MBC/TOC, and soil respire rate; increasing of reed height and yield, decreasing of weed diversity; affecting of transporting ability of Ca, Mg, K, Zn, and Mn , and improving of water shortage, salinity resistance and rhizosphere metabolized secretion conditions, all those improved the weak ecosystem.

总之，经过对生物塘-芦苇湿地系统处理造纸废水的研究，发现系统能有效去除废水中有机物，同时废水灌溉还极大的降低了土壤盐分，产生了一系列积极效应：系统内氮、磷、有机质增加；土壤微生物和酶活性增强；MBC/TOC及土壤呼吸强度提高；芦苇株高和产量增加，而杂草的多样性减少；同时也会影响系统内钙、镁、钾、锌、锰等离子迁移，改变系统受盐碱和缺水胁迫的现状和根际代谢状况，极大地改善了滨海盐碱生态系统现状。
