Sampling only from the surface of the soil C. Sampling at different depths and locations in an organized way D. Sampling only when it is raining 相关知识点: 试题来源: 解析 C。解析:本题考查土壤采样方法。在土壤采样过程中,应该有组织地在不同深度和位置进行采样,这样才能全面地获取土壤信息。随机...
By applying different small-scale ploughing treatments, we studied the importance of the soil seed bank and associated aboveground vegetation for increasing the diversity of degraded species-poor grasslands that were formerly arable fields. We focused on the different functional groups of species present ...
摘要: Importance sampling is an underappreciated Monte Carlo technique. The authors have used it with great success. They share their insights. Importance sampling is designed to reduce the variance of the estimators for a given-size sample

Based on the importance of soil moisture to climate change50, together with the negative correlationship between Pn and temperature under nocturnal weak light, we found that warming facilitated the cover of ACs more than that of LC2 and MC; AC2 more than AC1; and LC2 more than MC, and ...

Long-term monitoring of forest soils as part of a pan-European network to detect environmental change depends on an accurate determination of the mean of the soil properties at each monitoring event. Forest soil is known to be very variable spatially, however. A study was undertaken to explore...
The importance of the role of soil organisms in the restoration of plant communities is becoming widely acknowledged [57,58]. Soil inoculation can be used to promote the colonization of soil organisms at the start of restoration. This study now shows that inoculation with soil communities that or...
We evaluated the feasibility of extracting organic pesticides in soil using a hot-water percolation apparatus at 105 degrees C and 120 kPa pressure. Efficiency of the method was assessed by extracting six selected pesticides (acetochlor, atrazine, diazinon, carbendazim, imidacloprid, and isoproturon) ...
