In the light of the paleoenvironmental significance reflected by the radiolaria, graptolite, brachiopod,sponge spicule and the rock character, its suggested that the greyish green mudstone at the basal WufengFormation of the Goujiaya section would be probably deposited in 60 to 100 meters deep water, theGuanyinqiao bed in 50 to 80 meters deep, and the radiolaria-bearing silicalite from Wufeng Formation inwater with 200 to 400 meters deep. Combining the above-mentioned water depth with the sea-level changecycles, the change range of every one of the 5 cycles could be further conjectured. They were in ascendingorder: 20～120 m, 80～130 m, about 150 m, 50～250 m, and in excess of 200 m.

根据放射虫、笔石、腕足类、海绵骨针以及岩性等对古环境的指示意义，认为五峰组底部灰绿色泥岩段产出时水深约60-100m，观音桥层水深约50-80m，在晚奥陶世最大海侵期(对应于T.typicus亚带下部)，水深约400m，五峰组含放射虫硅质岩沉积时最小水深约200m，结合以上海平面变化的5次旋回，从而推算出各旋回海平面的变化幅度：在第①旋回，海平面变化范围大致为20～120m；在第②、第③和第④旋回中，海平面变化分别为80～130 m、大约150 m和50～250m；第⑤旋回的海平面升降幅度大于200 m。

Analysis of the morphological feature, diversity and abundance of graptolite, brachiopod and radiolaria indicated that the sea-level in the Yangtze basin underwent the change from rising to falling, then to rising again during the latest Ordovician to the earliest Silurian interval, and the maxium rising episode eppeared in the lower Tangyagraptus typicus Subzone and the maxium falling at the top of the Guanyinqiao bed.

笔石、腕足类、放射虫的形态、分异度和丰度的研究表明：扬子海盆晚奥陶世晚期至志留纪初期，总体上，海平面经历了上升→下降→上升的变化，海平面上升的最大阶段发生在Tangyagraptus typicus亚带下部，到观音桥层顶部，海平面下降到最低点。

Radiolaria is an important fauna among the marine micropaleontology, whose ecology knowledge is the base of paleoceanographical and paleoenvironmental reconstruction.

中国加入综合大洋钻探计划，势必会加快[JP2]我国古海洋学的研究步伐，放射虫作为海洋微体古生物中的一个重要类群，其生态学知识是重建古海洋、古环境的基础。

Distribution of biogenic silica content in surface sediments from deep water areas showed that it could not only reflect the paleoproductivity of siliceous micropaleontology in surface waters, but also indicate the strong or feeble upwelling. Thus, it was further confirmed that using biogenic silica content in sediments to trace upwelling and its change was effective and reliable. The analyzed result showed that radiolaria and poriferous specula have more contribution for biogenic opal, comparing with diatom in surface sediments from the northern studied area, probably owing to the diatom dissolved easily away and eaten by other organisms with little effort.

深水区表层沉积物中生物硅的含量分布表明，其不仅能反映出表层水体中硅质生物的古生产力水平，而且还能指示上升流的强弱，从而进一步证实了利用沉积物中生物硅含量来追踪上升流发育和变化的有效性与可信度研究结果还显示，在研究区域中北部表层沉积生物硅中放射虫和海绵骨针较硅藻占有更大的比重，这可能是由于硅藻易被溶解并易被其他生物体摄食的缘故。
