4 、在昌樂地區區分出三類主要的玄武巖： a ，牛山組含礦的堿性橄欖玄武巖，位於方山，含大量的大小不一的風化蝕變程度不同的地幔巖包體； b ，牛山組幾乎不含礦的堿性橄欖玄武巖，含少量地幔巖包體，且包體一般比方山小，多數已經遭嚴重風化而只留下空洞，含有相當數量的鈦鐵礦，主要位於北巖南部的蒼山，桃花山及喬官火山口。 -
Bivalve density in east tangsun lake was maximal while that in niushan lake and longgan lake were minimal. insect density in east tangsun lake was maximal but that in huang lake was minimal, and the differences of them among three lakes were distinct ( p 0. 05 ). zoobenthic density in east tangsun lake was maximal but that in huang lake was minimal, and the difference in two lakes was distinct ( p < 0. 05 )
在密度方面，寡毛類以龍感湖最高，牛山湖最低，且兩湖差異顯著（ p 0 . 05 ） ；牛山湖螺類明顯比其它三個湖湖泊高（ p 0 . 05 ） ；雙殼類以東湯孫湖最高，牛山湖和龍感湖最低；水生昆蟲以東湯孫湖最高，黃湖最低，且東湯孫湖與龍感湖和黃湖差界顯著（ p 0 . 05 ） ；底棲動物總密度以東湯孫湖最高，黃湖最低，且兩湖差異顯著（ p 0 . 05 ） 。 -
The species number of zoobenthos in east tangsun lake, niushan lake, longgan lake and huang lake were 36, 24, 33, and 18, respectively. the differences in species richness and species diversity in the four lakes were obvious
主要結果如下：東湯孫湖、牛山湖、龍感湖、黃湖四個湖泊底棲動物的種類數分別為36 、 24 、 33 、 18 ，各類群的種類數以及生物多樣性指數相差很大。 -
