The following results are made from this research: Assessing data quality and band combination of different bands in line with geo-target features in desertification areas, and determining basic bands for desertification monitoring. And understanding and studying the spectral features and variation rules of geo-targets in the experimental area, raising that it is the basis of geo-targets information collection with imaging spectrometer data to understand spectral features and variation rules of geo-targets, realizing that in a great extent spectral-integrated-form-based classification method can remove the phenomenon of "different spectrum with same objects" resulted from reflection ratio curve translation because of the angle change among sensor, targets and observation direction, and the average and variance images can be introduced to solve the problem of two kinds of geo-target with similar spectral forms and much different values of whole reflectionratio. It is suggested that "red edge" range bands of vegetation, which has close relationship with vegetation cover and biomass, is the main characteristic bands and important basis for careful vegetation classification and quantitative retrieval, and pixel-based derivative spectral analysis is very useful for removing the effects of soil background values and quantitatively retrieving vegetation biomass and cover. The remote sense quantitative retrieval model is developed for main appraisable factors of desertification monitoring assessment with imaging spectrometer data and then the applicability of model is analyzed.

According to the life form of species and their roles in communities, 6 species groups are used to do ordination analysis and environmental interpretation. The result suggests that:①Despite the strong man-made disturbance at lower altitude sites, the number and character of evergreen species show an change along the altitude gradient.②The rare and endangered species concentrated at two sectors along altitude gradient, corresponding to the upper and lower borders of the mountain mixed forest belt of evergreen and deciduous broad-leaved species.③The pioneer tree species concentrated on the middle and upper positions at lower elevation.④The deciduous accompany tree species show a great diversity on middle and lower position at middle and higher elevation.⑤Coniferous species differentiate along elevation and local topographical gradient.⑥Deciduous species in Quercus, Castanea, Fagus, Carpinus genus as well as coniferous species play primary community-constructing roles at different topographical position at Dalaoling region.

The basic diploid number of chromosomes in the family Cobitidae was deemed to 2n=50. The C . sinensis with 2n=40 may originate from the ancestor of the subfamily Cobitidae. The C sinensis with 2n=90 which reserved all of 40 original chromosomes maybe result from heterologous hybridization among some fishes of the subfamily Cobitidae. The C . sinensis with 2n=76 is probably a branch of hybrid offspring.

鳅科鱼类染色体的祖先二倍数是2n=50，2n=40的中华花鳅可能是由类似于泥鳅的2n=50的鳅亚科祖先经罗伯逊易位2n=50→48→40转变而来的。2n=90的中华花鳅保留了初始的40条染色体，它可能是由2n=40的中华花鳅与同为鳅亚科的其它鱼类杂交后演化而来的。2n=76的中华花鳅并非异源三倍体，它可能是杂交后演化的一个分支。

The experimental results indicated that under the steady operating conditions, the ignition timing of the base fuel (PRF90-90% iso-octane+10% n- heptane), which is equivalent to RON 90, delayed and the peak value of the heat release rate was low compared to the base fuel with single additive (Ditert-butyl peroxide-DTBP, Dicumyl peroxide-DCP, Tert-butyl hydroperoxide-TBHP, Tert-butyl cumyl peroxide -TBCP or Cumene hydroperoxide-CPO) which advanced ignition timing and increased the peak of the heat release rate obviously.

Results showed that planktonic Prorocentrum were assembled to onegroup while benthic Prorocentrum were assembled to another group. The percentagesof the bootstrap values were higher than 95%. The results demonstrated that theplanktonic and benthic Prorocentrum should belong to different genus. Furthermore, the resulting phlogenetic structure showed the percentages of thebootstrap values (98%-100%) of Alexandrium in NJ and ML trees were significantlevers and belong to one group, divergently with genus Gonyaulax.
