SOC and TN showed significant positive correlations with soil water content(r=0.913,0.874,n=117,p=0.000)and significant negative correlations with annual mean air temperature(r=-0.883,-0.869,n=10,p=0.001),which indicated that climate factors controlled SOC and TN distribution pattern along the altitudinal belt.
The yield variability caused by growth time and location as well as the effects of climate factors on the yield of linseed were analysed base on the data collected from 71 location of Gansu province during 1981—2000 using EOF,wavelet and regression methods.
According to the auther's phynological observation from 1971 to 1990 in Kuduer forestry area and the analysis of climatic data of Kuduer,Yakeshi,Tulihe area and so on by statistic method happenings of cone-fly of xingan larch Strobilomyta lariciola is related to some climate factors which constototes the happening degree specimen of weather type.
Discriminant model of urban zonal vegetation types in Northeast China was established with principal component analysis (PCA) and multiple group discriminant analysis (MGDA). The results showed that 210×7 matrix was established with variables of 210 cities (towns) and 7 climate factors. According to classification and ordination from principal component analysis, there were obviously 7 city (town) zonal vegetation types.
The input variables used are the annual means of the climate variables and the parameters of climate factors taking into account the surface properties.
A major problem of climatology are the relationships among climate variables and between climate variables and climate factors on a climatological time scale.
Labor force, transportation, qualityof life, and overall business climate factors are consistently ranked highestby business executives, and state tax, finance, plant services, and marketingassistance are consistently ranked low.
The results of regression analysis indicate that the variability in departmental theft is accountable in terms of a linear combination of demographic, personality, and climate factors.
Also, climate factors related to SDS and associated dustfalls were discussed.
