临江工业区位于杭州市萧山区东北部，与杭州主城仅一江之隔，工业区坐落在钱塘江的东南翼、杭州湾的核心区，距杭州萧山国际机杨和杭甬高速公路、杭金衢高速公路25公里，离亚洲最大的纺织品集聚地中国经纺城30公里，至杭州市中心和萧山城区40公里，塘新线、红十五线和已动工建设的梅林大道及钱江九桥连接线与园区规划建设的主干道相连接，交通十分便利，区位优势十分明显，市场信息灵通，发展空间巨大。

The ultrastructural changes during the development of sieve element companion cell complex (SE/CC complex) in Populus deltoides were investigated using electronic microscopy. The result showed that SE and CC tome from the same secondary phloem mother cell. The development of sieve element went through three stages, i. e. immature, mature, and degenerate stage. In immature stages the sieve element presented radial expansion, cell wall thickening, and production of sieve plastid and P-protein. The cytoplasma selectivly autolysed in mature stage. At the same time, karyoplasm was dispersed, and nuclear envelope was not clear, or karyoplasm was disorgnized, and nuclear envelope was clear. The karyopalsm finally turned into P-protein. In degenerate stage, the cytoplasm completely disappeared, and the function was lost.

利用电镜技术研究美洲黑杨次生韧皮部筛管和伴胞发育过程中细胞超微结构的动态变化，观察到筛管和伴胞由同一个次生韧皮部衍生细胞分裂分化形成筛管约发育历经未成熟期、成熟期和衰退期的变化未成熟期筛管分子表现为细胞的径向扩展、壁的增厚、筛管质体和P-蛋白质的产生；成熟期筛管分子细胞组分发生选择性自溶，细胞核核质弥散状，核膜不清晰，或核膜清晰而核物质降解，最后细胞核完全解体转化为P-蛋白质类的物质；衰退期筛管分子细胞质完全解体消失，失去功能。

The author investigated the community of grasshoppers in Changbai Mountain area during the period of July to September 2001, complementally collected specimen and systematically collected and measured environmental factors from July to October in the following year, and consulted to specimen collected by Fengling Zhang and Yanlong-yang in 1979, 1980 and 1981. By analyzing and classifying the data of five years, the author analyzed the community construction and ecological adaptability of the grasshoppers in the area. The main aspects dealing with the grasshoppers are as follows:(1)the community construction and faunal geographical elements;(2)characteristics of their ecological distribution;(3)vertical distribution of grasshoppers in the northern slop;(4)the relationship between environmental factors and differences in shape of grasshoppers in different vertical belt of northern slop, etc.

本文作者于2001年7～9月间系统地调查了长白山地区的蝗虫，并于2002年的7月到10月间对标本进行了补充采集，并对环境因子数据进行了系统的测量和收集，同时参考张凤岭、杨彦龙先生1979、1980和1981三年采集的标本，通过对标本的鉴定和整理，采用五年的野外工作数据，对长白山地区蝗虫群落结构及生态适应特性进行了研究，主要研究内容包括：蝗虫的群落结构及区系地理成分；蝗虫生态分布特点；保护区北坡蝗虫垂直分布及不同垂直带内蝗虫的形态差异和环境因子之间的关系等方面内容。
