Among many factors related to soil respiration, the temperature is the most important one.

土壤呼吸对温度变化的响应已成为生态学研究的重要内容之一。

Soil microbiotic crusts play important roles in vegetation restoration and revegetation in desert area.

土壤生物结皮在沙漠地区植被恢复和重建中具有重要的生态学意义。

It builds a theoretical system of revegetation and restoration through the study on correlative theories of revegetation ecology and sum-up of practical experience of revegetation.

通过对恢复生态学等相关理论的研究以及植被恢复和重建实践经验的总结，构建了植被恢复与重建的理论体系。

The ecological significance of the different responses of seedling regeneration to light environmental heterogeneity for biodiversity maintenance in forest, forest succession and revegetation were discussed.

接着从森林物种多样性维持、森林演替和植被恢复的角度探讨了幼苗更新对光环境异质性不同响应的生态学意义。

Different biological and ecological characteristics, virulence, sporulation, conidia bourgeon, Protea-Bse activity leve and colony growth of 6 strains of Beauveria bassiana were measured respectively. The results were calculated by grey relational analysis and the optimum sequence was built from the professional comparison of each strain's characteristics. Two strain's have a potential of appling in mass production, BD-B015 and BD-B038 were abtained. The revisory mortality to Laphygma exigua Hubner were 88.33% and 86.70%.The infected rate were 86.67% and 85.27%.

测定初筛获得的6个球孢白僵菌菌株的毒力、产孢量、萌发率、胞外蛋白酶活性及菌株生长速度等多个生物、生态学指标，从专业角度构建最优序列，经灰色分析和不同菌株毒力效价显著性比较，筛选出了两株具有较大生产潜力的优良菌株BD-B015和BD-B038，对甜菜夜蛾的校正死亡率分别为88.33%和86.70%，僵虫率分别为86.67%和85.27%。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
