The purpose of this paper is to analyse mathematical models used in environmental modelling.
      
With a better understanding on radiolysis of isoquinoline, this study is of help for its degradation and for environmental protection.
      
An improved ion chromatographic method for determination of trace levels of perchlorate in environmental water
      
An improved ion chromatographic (IC) method was developed to determine trace levels of perchlorate in environmental water samples.
      
The method had been applied to the determination of perchlorate in some real environmental water samples and recovery was between 93% and 113%.
      
The syntonic frequency of the MOS RO changes in relation to many environmental elements, such as temperature, source voltage, and so on.
      
Distribution of Landscape Elements Along Environmental Gradients in Over-Cut Forests
      
The method of trend surface analysis was used to analyze the distribution of landscape elements along environmental gradients in Jingouling forest farm, northeast China's Jilin Province.
      
In future studies, the biochemical factors and the environmental and biological factors controlling respiration should be emphasized for precise estimation of total CO2 efflux.
      
The sap flow density, water consumption, and related environmental factors were also measured using thermal dissipation method and ICT-2000TE (Transpiration-Environment) automatic measuring system for tree transpiration and environmental factors.
      
A study on the relationship between biodiversity and soil-erosion processes could help us understand the environmental evolution of Earth.
      
kwangtungensis; 4) variability in spatial distribution among the 105 canopy tree species could be attributed to variations to site environmental factors.
      
The results from CCA and cluster analysis indicated that environmental factors influenced the distribution and ecological characteristics of the plant species in the forest community dominated by P.
      
However, only two morphological indices, the middle apical bud and the tooth of leaf base, are unstable, which indicates the extensive influence of environmental factors.
      
Using principles of ecosystem health quantitative assessment and diagnosis index selection, 17 factors were considered from three aspects: resource and environmental capacity, social and economic impact, and ecological services.
      
In addition, it is also revealed that by stepwise regression analyses photosynthetical active radiation (PAR), temperature and wind speed are the main environmental factors affecting sap flow velocity.
      
The contents of the tested microelements in soil fauna had significant correlations with their environmental background values, litter decomposition rate, food habit of soil fauna, and its absorbing selectively and enrichment to microelements.
      
Response of canopy stomatal conductance of Acacia mangium forest to environmental driving factors
      
The environmental factors, including relative humidity (RH), precipitation, vapor pressure deficit (VPD), photosynthetically active radiation (PAR), and air temperature (Ta) were recorded simultaneously.
      
Nighttime water recharge had no significant correlation with environmental factors, but was well correlated with the diameter at breast height, tree height, and crown size.
