查询词典 microbiotic

There is a significant difference in daily change of soil moisture content at depth of 5 cm between the areas with and without microbiotic crusts.

结皮覆盖区与无结皮覆盖区土壤水分的日变化特征明显不同于距地表5cm处，而其他各土层的变化趋势则较为一致。

Objective: In order to investigate the relationship among microbiotic antioxidant、free radical metabolism and reproductive ability, to discuss free radical metabolism influence the body growth as well as the development of organs.

目的：本试验通过微生物源性抗氧化剂和LPS对机体自由基代谢水平进行调控，研究微生物源性抗氧化剂、自由基代谢和机体繁殖性能的关系，探讨自由基水平对机体的生长发育、器官发育以及性发育等的影响，从而实现通过营养调控技术提高机体的繁殖性能。

In the future, rover-based explorations of the hydrate deposits and clay beds could reveal solid evidence for a red planet that once thrived with microbiotic life.

在未来，以自行装置为基础，对氢氧化物沉淀和粘土层的探测，可能会提供可靠的证据：在这颗红色的行星上，微生物曾经旺盛地生长着。

The contribution of soil microbiotic crusts to the diversity of insect species may be attributed to the facts that it stabilizes soil surface, improves soil environmental and there by provides suitable habitats and some food sources for the insects.

生物土壤结皮对荒漠昆虫多样性的贡献可能是由于稳定了土表、改善了植被系统中的土壤环境，为昆虫，特别是幼虫阶段提供相对适宜的土壤生境或部分食物来源。

Intercepted precipitation and enhanced evaporation by microbiotic crusts were the two main factors threatening the water reservoir in sand dunes.

微生物结皮拦截降雨和提高蒸发，是微生物结皮威胁沙丘土壤水库的两个重要因素。

So studying the processes and mechanisms of soil hydrology of microbiotic crusts as well as analyzing its influence on soil water conditions in fixed dunes will play an important role theoretically and practically in understanding the evolution of artificial vegetation community in fixed dunes and the security of artificial sand-fixing vegetation system.

因此，通过野外试验揭示微生物结皮对土壤水文过程的影响和机理，评估其对雨养植被固沙区土壤水环境的影响，对于认识固沙区人工植被群落的演替和人工植被固沙体系的安全性都有着重要的理论意义和实践意义。

Microbiotic crusts had a high capacity of evaporation than the shifting sand dunes. During the evaporation process of one week after rainfall, the total evaporation in artificial vegetation regions constructed in 1956, 1964, and 1981 were 6.05, 4.99 and 4.23 times respectively as the total evaporation in shifting sand dunes.

微生物结皮有着比流沙区更高的蒸发能力，在雨后一周的蒸发过程中，1956、1964和1981年人工植被区的总蒸发量分别是流沙区总蒸发量的6.05、4.99和4.23倍。

The surveyed results show that as compared to the uncovered vegetation area, the existence of soil microbiotic crusts in the Tengger Desert region significantly increases the diversity and abundance of insect species, especially the diversity and abundance in the quadrats mainly covered by moss and lichen crusts are significantly higher than those in the quadrats mainly covered by cyanobacteria and algal crusts.

结果表明：与无结皮覆盖的植被区相比，生物土壤结皮在地表的覆盖显著地增加了昆虫的多样性和种的丰富度，其中以苔藓和地衣为主的结皮覆盖的植被样方中昆虫种的多样性和丰富度显著地高于以蓝藻和藻类为主的结皮样方。

By field sampling, some original soil microbiotic crusts were gathered and their physico-chemical properties were analyzed. The results revealed that the longer the sand dunes have been fixed, the thicker and the more biocrusts are formed. The thickness of the crusts under four different types of plant community ranges within 0.3 ~ 1.5cm.

物理结皮通常是土壤粘粒在雨水、径流等外力的物理作用下，使土壤表层孔隙堵塞而成型的一层土表硬壳；生物结皮是有不同种类的低等生物组分与其下很薄的土壤共同形成的一个复合的生物土壤层[2]。
