In different degree of saline and alkali conditions controlled in lab or under field, contents as followed were determined: the absorption, transportation and distribution of major cations Na~+, K~+, Ca~(2+and Mg~(2+) in indicator plant; organic solute, and antioxidase activities, including superoxide dismutase, catalase and peroxidase POD characteristics of individual, population and community of the plant. Responses of the indicator plant to environment from physiological to community aspects were systemically discussed in this document.(1 Vegetional characteristics and edaphic indicators including bare patch index, dry biomass, percent cover by perennial plants, growth indicators of Leymus chinensis, soil organic matter and pH were sensitive to saline-alkali grassland degeneration.

运用室内控制和野外试验相结合的方法，调查和测定在不同土壤盐碱条件、不同季节里，主要元素Na~+、K~+、Ca~(2+)、Mg~(2+)在植物体内吸收、运输和分布的变化状况；研究不同土壤离子浓度下，指示植物体内渗透调节物质——脯氨酸和糖类、超氧化物歧化酶、过氧化物酶和过氧化氢酶活性等指标的变化响应情况；研究不同盐碱梯度下，植物个体、种群、群落的特征；系统的从生理生态角度探讨指示植物对盐碱环境的响应：(1)植被特征指标：裸地指数、生物量、多年生植物覆盖率；羊草生长状况指标：土壤有机质含量、pH可作为松嫩平原退化评价的指标。

According to the rate of occurrence and the average biomass, 33 species of phytoplankton, 34 species of zooplankton and 6 species of zoobenthods were the important species in the inland saline waters in North China.

根据出现率和平均生物量，有33种浮游植物、34种浮游动物和6种底栖动物为三北地区内陆盐水的主要种类。

The soil microorganisms quantities, microbial diversity index, microbial biomass carbon and the cellulose decomposition strength significantly reduced with increasing of heavy metal concentration, but the soil basal respiration rate were positively enhanced. The soil urease, alkaline phosphatase and polyphenol oxidase in the lead zinc mining area were sensitive. The invertase and catalase were not obvious inhibited to the heavy metals.

该矿区土壤微生物区系组成和微生物活性显著不同于临近非矿区土壤，随着重金属含量的增加，土壤微生物数量、微生物多样性指数、微生物生物量碳以及纤维素分解强度均显著降低，但土壤基础呼吸却明显升高；土壤脲酶、碱性磷酸酶、多酚氧化酶对铅锌矿较为敏感，而蔗糖酶和过氧化氢酶受到的抑制作用不明显。

Research shows that algae from open water body are greatly trapped in the macrophyte-covered littoral zone ,and decomposed there.

研究发现植被型岸边带可以大量捕获来自开阔水体的漂浮藻类，并使之在岸边区迅速降解，从而减少了进入水厂的藻类生物量。

Malolactic fermentation is a very important processing technology for deacidificaton in modern winemaking.

苹果酸乳酸发酵是现代葡萄酒酿造工艺中重要的生物降酸手段。MLF是L 苹果酸在乳酸菌的苹果酸乳酸酶催化下转变成L 乳酸的酶促反应过程，该过程没有底物水平的磷酸化，但在MLF过程中苹果酸确实能够刺激细菌的比生长速率，增加细菌生物量。
