本文从分子化学结构的角度出发，论述分析了甜菊糖苷甜中带苦涩后味的根本原因，甜度、甜味与苷元的C连接部位和连接葡糖基数的关系；对于现今改进甜菊糖苷的苦涩味的酶化方法，作了深入的比较、论证，并指出新的科学技术方法。

Chromosome evolution: x= 11 occurred in most genera of Komarovieae through Selineae; other basic chromosome number originated multiple times independently in the subfamily Apioideae; For Pleurospermum and Pimpinella, the basic chromosome number of each coincide with their phylogenetic placement.

从性状演化图上看，整个芹亚科的染色体祖先状态可能为 x= 11或者 x= 6，而且亚科内的大多数类群均保持了 x= 11这一祖征；对于其它基数，一般在芹亚科内多次独立起源，构成各自的自征或者共有衍征；对于多系类群，如棱子芹属和茴芹属，染色体分析的结果很好的支持了他们各自的系统位置。

Potaninia mongolica Maxim, is recorded in the Chinese plant red book in 1992, as one of rare and endangered plant. More and more attention has been paid to its important ecological effect, ancient floristic geographic element, specific morphology of cardinal number three in Rosaceae and also to its obvious economic value.

绵刺是国家二级重点保护的珍稀濒危植物，1992年被收录于中国植物红皮书，它以独特的三基数形态特征而区别于蔷薇科其它植物，同时绵刺在阿拉善荒漠中具有不可替代的生态作用、古老的区系地理成分、重要的经济价值等诸多特点越来越引起人们的重视。

The analyses of social and economic development indicate that, up to 1998, the total population in Yijinholo County is 143, 949 persons, the population density is 24 persons per square kilometer, large population number results in land exploitation for food and overgrazing in rangeland. The change in temporal and spatial pattern of landuse from 1977 to 1998 demonstrates that mobile sand dunes was replaced by rangeland and woodland and partial shrubland in the middle of study area changed into rangeland and farmland from 1977 to 1987, while mobile sand dunes and rangeland transformed into shrubland and farmland in a small parts from 1987 to 1998, the above-mentioned change is proved by the change of fractal dimension index and fragmentation index at landscape and its element levels.

对近50年来伊旗社会经济发展的分析结果表明，虽然人口增长率基本上呈下降趋势，但由于人口基数较大，截至1998年底，伊金霍洛旗的人口总数达143949人，人口密度为24人／平方公里，较高的人口密度带来了更多的生存需求，使得大量的草牧场被开垦，而剩余的则严重超载。1977-1998年间伊土地利用结构总体格局变化的分析结果表明，1977-1987时段内主要是流动沙地为草牧场和乔木林地所取代，伴随着中部的部分灌木林地转换为草牧场和农地：而1987-1998时段内主要是草牧场和流沙地为灌木林地和农地特别是灌木林地所取代，而景观及各景观要素的分维度指数和破碎度指数的变化也充分证实了这一结论，虽然在前10年（1977-1987年）中大面积的灌木林被砍伐，但土地利用格局的整体变化间接地反映出该时段内荒漠化的状况正在发生逆转。
