尤其是由冷湿到暖干的气候转换时期，频繁而大幅度的气候变化影响湖泊水环境的稳定连续性，限制了介形虫等湖泊生物的生存，造成湖泊生态环境系统的破坏。

The dramatic climate change , especially in the transitional period from cold and wet climate to warm and dry climate , limited the continuity of aquatic environment and restricted the survival of ostracode , and broke down the lake ecosystem .

介形虫的种数与个数具有由南向北、由河口海岸到陆架外缘随水深变大而增加的趋势。

As shown by statistics ( Tab . 2 , Figs . 1 , 2 ), both abundance and species diversity tend to increase from the north to the south and from coast to the outer edge of continental shelf with increasing water depth .
