The study history of cave invertebrate in China is summarized in this paper. We list new species of Chinese troglobiotic invertebrate found over the past twenty years, and two types of cave invertebrate are divided according to the differences of the habitat: terrestrial community and aquatic community. The review also emphasizes the current research on Arachnolida, Diplopoda, Insecta, Crustacea and Castropoda.

结果表明，禾本科杂草和石竹科杂草是烟稻轮作烟地的主要恶性杂草，其群落结构是单子叶杂草和双子叶杂草组成的混合群落。

The principal factor affecting the diversity was species evenness.

群落多样性在中稻生育中期最高，群落均匀度是影响多样性的主要因素。

Based on RAPD data, Nei's gene diversity index averaged 0.2523 and Shannon's information index averaged 0.3730, while Nei's gene diversity index averaged 0. 252 3 and Shannon's informative index averaged 0.3958 based on DOGE data.

结果表明：RAPD分子标记显示不同浓度废水驯化的细菌群落的Nei's指数平均为0.252 3，Shannon's信息指数平均为0.373 0；而采用DGGE技术得到不同浓度废水驯化的细菌群落的h平均为0.252 3，I平均为

The paper adopted the method of Braun-Blanquet school of vegetation ecology. Typical plots were chosen in order to investigate the vegetation type of the main parks in Kaifeng city. The analyses were based on defining the least area of communities with the usage of abundance dominancy and combining cover coefficient.

采用植被生态学中法瑞学派的研究方法，在确定群落最小面积的基础上，选取典型样地，运用多优度指数并结合盖度系数对开封市铁塔公园、禹王台公园、龙亭公园的植被类型、生境特点及各类型的群落生态学特征进行较为详细的研究。

Macrobenthos in this area can be defined into five types by ecological character, dominant key species of each group are presented.
