At the same time, the intensity ratio of the ICT fluorescence to the LE fluorescence, I〓/I〓, shows a "bell"-shaped variation with increasing CTAB concentration The intensity ratio was found to level off after the CMC of CTAB Together with the data from UV-Vis absorption spectroscopy, electric conductance measurements and the control experiments with tetramethylammonium bromide, it was concluded that the"bell"-shaped variation in the intensity ratio before CMC is due to the formation of premicelle aggregates consisting of ICT fluorophore and CTAB.

此时，ICT荧光强度与LE荧光强度之比，I〓/I〓随CTAB浓度增大而呈&钟形&变化。当CTAB浓度高于CMC时，I〓/I〓为一常数。根据紫外-可见吸收光谱，电导以及四甲基溴化铵对照实验的结果可知，当CTAB浓度低于其CMC时，I〓/I〓的&钟形&变化是由于长链对二烷基氨基苯甲酸与CTAB组成的胶束前簇集体形成所致。

Three primer pairs located in psbA~trnK, psbB~psbH and trnR-ACG~trnN-GUU regions were applied in phylogenetic analysis according to Maximum parsimony and Neighbor-joining methods. The consistent results between the phylogenetic analysis and taxonomy indicated the application potential of the three primer pairs in phylogenetic analysis and species identification. However, due to no sequence variation observed in amplified regions between two vegetable soybean varieties (KS5 and KS8), two cowpea subspecies (Vigna unguiculata ssp. cylindrica and Vigna unguiculata ssp. sesquipedalis), and among three rice varieties (TNG67, TK9, and TCS10), the three primer pairs are not effective in identifying variation within species.

The dissertation modifies the model of Holdridge's indexes of lifezone according to the features of the ecological climate of Xinjiang. The influence of the variation of vegetation caused by the climate variation of Xinjiang in recent decades is also analyzed. In recent 40 years, the type of life zone hasn't changed, the area and number of patch changed only. The diversity changed but not too much..That is, diversity of life zone changed in little range, the whole entiroment is still be a rather stable state, whill be goo for desertation expand contrandictorily.

根据新疆生态气候特征和生物地理规律对Holdridge生命地带分类模型进行修正，分析新疆近几十年来气候变化所引起的植被变化对于新疆土地荒漠化的影响。40多年来，新疆生命地带的类型数量并没有产生变化，只是各类型的面积和斑块数的变化，多样性有所波动，但是波动不大，也就是说生命地带多样性的震荡幅度不大，整个生态环境处于一种相对稳定的状态，这种稳定的生态环境状态有利于荒漠化的逆向发展； 7。
