English translation for "soil air"

土壤空气
土壤中空气

Example Sentences:

	1.	Its removal draws soil air into the hole . 其拔起的动作会把土壤气体抽入孔中。
	2.	Determination of carbon dioxide content in forest soil air 森林土壤空气中二氧化碳含量的测定
	3.	But variation of the co ; concentration in the bottom soil show that sink effect of carbonate rock on the soil air co2 ( 2 ) the diurnal observation results of soil co2 dynamics in the different vegetation show that the soil co2 concentration in the bare land is sensitive to environment , but the soil co ; concentration in the other experimental site , which covered with vegetation , restrain the variation 在土壤?大气界面上，土壤表层可为大气提供游离co _ 2 ；而土壤深部co _ 2浓度的变化则显示下覆碳酸盐岩对co _ 2有吸收作用。 ( 2 )在不同植被系统中，土壤co _ 2昼夜动态变化进程不同。观测资料表明：裸地对外界环境的变化相当敏感，而有植被覆盖的竹林和草甸对土壤co _ 2浓度动态变化有平抑作用。
	4.	New achievements having been obtained in this field show that co2 participating in karst process in the epikarst dynamic system mainly comes from soil air co2 created by the organic carbon , in other words , although karst is a kind of biochemistric action in nature , distribution and transmit and cycle of carbon rely on changes of soil organic carbon . soil organic carbon is the greatest carbon storeroom . soil respiration emission of co2 is the most important passing entrance in carbon cycle of epikarst ecosystem 已有的研究表明：参与岩溶作用的co _ 2多数属于土壤中生物成因，也就是说，尽管岩溶作用是一种自然界无机化学作用，但碳的分布与转移及循环仍以生物活动为纽带的土壤碳积累为转化中心，土壤有机碳构成系统最大的碳库，土壤呼吸碳表现为该系统中最重要的碳流通途径，因此进行土壤co _ 2浓度观测及其影响因子分析是研究表层带岩溶生态系统运行机制和全球碳循环的首要条件。
	5.	The research include : 1 ) measuring co2 concentration in the soil air and vegetation air by using co2 measuring instruments ; 2 ) measuring the releasing rate of co2 coming from soil surface by using alkaline absorbing method ; 3 ) measuring the hydrochemical indexes of soil water . the research results are as follows : ( 1 ) the author has made field observation of depth distribution of soil air co2 in the mt . jinfo karst experiment site . the results show that two concentration gradient , soil to atmosphere and soil to carbonate rock , are form 本次实验以典型的亚热带岩溶分布区?金佛山自然保护区为例，选择了岩溶洼地内的高山草甸和靠洼地边缘地带的方竹林、裸地以及石林内的乔木林4个样地，对土壤co _ 2浓度空间分布规律以及昼夜动态和日动态变化状况进行了观测，获得了如下新的认识： ( 1 )土壤中co _ 2浓度分布的观测结果表明，土壤中具有土壤-大气、土壤-碳酸盐岩两个方向的co _ 2浓度梯度。
