Most of water-soluble cyanine dyes have -SO3H and –COOH in their molecules, which will influence the biomolecules' functional characters. A new kind of water-soluble cyanine dyes with several cations in molecules were designed and synthesized, preparation conditions of intermediate and dyes were researched and optimized, the yield of dye is 25%. The novel kind of cyanine dye are water-soluble , spectrum characters was researched , all the dyes were charactered by 1H NMR and TOF-MS, spectrum in different solvent of novel dyes were focused on, one of the kind dyes show higher fluorescence quantum yield than the result reported. Because of several cations in the structure, it is promising when used in DNA assay and other bio-assay field.

大多数水溶性的菁类荧光染料分子结构中都带有-SO3H和-COOH等基团，过多的阴离子的引入容易造成对生物分子的功能属性的影响，本论文设计并合成了分子结构中带有多个正电荷的水溶性的一类新型菁染料，考察并且研究了中间体和染料的合成条件，最终的目标产物产率达到25％，染料通过了质谱和核磁的表征，新型的染料具有良好的水溶性，研究了新染料在多种溶剂的的光谱性质，其中一种染料的在水中的荧光量子产率比文献报道得到了提高，由于富集了正电荷，这类菁染料在DNA标记等生物中有一定应用前景。

The Paper addresses itself to research on techniques of chemistry disposal by changing characters of Jute while it's in the shape of fiber, the spinning of Jute with changing characters, the weaving techniques and the finishing functional disposal of carpet. And on this basis the small sample of weaving carpet which is made of Jute are developed.

Thethesis compares the characters of ecosystem service in different district, main drainage basinand different segment in it, confirms the rules that the ecosystem service value is higher insouthern area than northern area and different characters along river and ridge. The ecosystemservice value is decreased regularly with the increasing of population density and elevationby compared analysis. The results of the ecosystem service values in 1981 and 2001 shows arule that ecosystem service value is steady for whole researched region and fluctuate in localarea in LRGR.

本文对比了各行政区、主要流域以及流域内部不同区段的生态系统服务功能特点，确定纵向岭谷区生态系统服务功能价值存在着南高北低的空间分布规律，且在河流、山脊处有着不同的变化特点；通过分析不同人口密度和海拔梯度下生态系统服务功能的价值，得出生态系统服务功能价值有随人口密度和海拔升高而下降的规律；通过对比81年与2001年生态系统服务功能价值的变化，阐述了纵向岭谷区生态系统服务功能价值总体稳定、局部变化的规律。

300 pieces of idioplasm resources of the Tibetan edible cultivation spring naked barley is identified for characteristic of shape, agronomic characters, rust-resisting property and grain thick protein,β-grape polymerization sugar and Vitamin E and so on from the Tibetan different region, which are analysed result in, for one thing, multiplicity of Tibetan spring naked barley is quite rich for the variation of the awn, leaves and the grain color, and multiple property are highest; Secondly, it has some fine hereditary characters of early maturation, big spike, many grains, many arrises and the strong anti-rust quality; Thirdly, genetic potential which is used possibly is enormous for characteristic of dense spike, exiguous spike, naked grain , the hook awn, short stem, the anti-rust and so on ; Fourthly, thick protein,β-grape polymerization sugar and Vitamin E of grains are rather difference to environmental condition of the various areas.

从西藏各地征集的300余份食用栽培春青稞种质资源，从形态特征、农艺性状、抗锈性和籽粒粗蛋白、β-葡聚糖含量、维生素E等特征特性鉴定、评价。分析结果认为：（1）西藏春青稞多样性极为丰富，如芒、稃和籽粒颜色，具有变异最为丰富，多样性最高的特点；（2）具有早熟、大穗、多粒、棱型多，以及抗锈性强等和耐各种不良环境因素的优良遗传性状；（3）具有密穗、稀穗、裸粒、钩芒、矮生、抗锈等可利用基因潜力巨大等特色；（4）籽粒粗蛋白、β-葡聚糖、维生素E等成份因各地区环境条件不同差异较大。

The results showed that except pods of main inflorescence, the other characters of the sterile and normal cytoplasms had not significant difference by t test. The correlation coefficients of length of main inflorescence, No. of first time branches and glucosinolates between sterile and normal cytoplasms was at 5 percent significant level, but correlation coefficients of the others was not significant. There were positive effects of male sterile cytoplasm on glucosinolates and weight of 1000 seeds, but different effects on the other characters when combinations were different.
