Examples
- Co2 ' s respond to the temperature in forest land is more moderate than that in the bare land , indicating vegetation ' s role of restraining to the carbon cycle
乔木林内的coz对温度的响应比裸地内c02对温度的响应要和缓些，显示了植被对碳循环的“平抑”作用。 - We selected two experimental sites - forest land and bare land to carry out the research . the research including : co2 concentration , temperature , air humidity and rainfall . we probed into the principle of carbon cycle in different elevation and the effect of vegetation to carbon cycle
故，本次试验以典型的亚热带岩溶分布区中的金佛山自然保护区为例，选取乔木林和裸地两种岩溶生态系统类型作为研究对象，对co _ 2浓度、温度、湿度、降雨量等进行观测，探索在不同海拔高度上，其碳循环的机制及有无植被覆盖对碳循环运行的影响。 - The research results reveal that the total value of soil conservation in yuanzhou district adds up to about 8634 . 39 million yuan ( rmb ) per annum , of which , about 8148 . 62 million yuan is of holding nutrient for n , p , and k , about 19 . 43 million yuan of decreasing soil loss , and about 466 . 35 million yuan of reducing reservoir silt different types of vegetation produce different environment benefits
原州区退耕还林还草植被发挥效益后，每年保持土壤的总价值为8634 . 39万元，其中减少养分损失价值为8148 . 62万元，减少土地废弃价值为19 . 43万元，减轻泥沙淤积价值为466 . 34万元；各种退耕类型的土壤保持功能大小依次为：还乔木林、还灌木林、还人工苜蓿草地、还经济林。 - To day , the burned blank was almost restored . the proportion of forest area increased 47 . 6 % in 1987 to 81 . 3 % in 2000 , among the forest landscape patch types , coniferous is the dominant , about 47 . 6 % , which is the result of the intensive planting after fire
各景观斑块类型的变化强度迥然不同，林火迹地已基本恢复，并基本处于良好的发展状态，目前研究区主要乔木林(针叶林、阔叶林、针阔混交林)面积已占研究区总面积的81 . 3 ，演替顶级群落针叶林已达47 . 6 。 - 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。
