1·But the environment of tidal flat is deteriorating.

但是沿海滩涂生态环境不断恶化。

2·On the tidal flat, the mangrove meashes spread widely.

在潮坪上生长着大量的红树林。

3·Tidal flat environments are favorable facies to develop karst reservoirs.

潮坪环境是有利的储集岩发育相带。

4·The sandstone body of Yanghugou formation deposited mostly from tidal flat and lagoon.

上古生界石炭系羊虎沟组砂体以潮坪、泻湖沉积为主；

5·So enzyme activity could be used as an index for evaluation of tidal flat soil fertility.

因此，土壤酶活性可以作为该土壤肥力的指标之一。

6·In the second stage (Taiyuan Age), sub-tidal, tidal flat and delta occurred alternatively.

第二阶段（太原组）潮下带、潮坪、三角洲环境交替出现；

7·This mode goes from low to high with the heighten of filling up and enlargement of sandbank (or tidal flat). 3.

这种自然演替模式随着滩涂（或沙洲）淤积增高和面积的扩涨，即按高程从低到高的顺序进行。

8·So it is very necessary to study tidal flat environment of Hengsha, and to qualitatively assess the environment.

因此，针对横沙岛目前的潮滩环境进行研究，并就潮滩质量和发展趋势进行评价非常必要。

9·The national nature reserve of rare bird in Yancheng is the biggest coastal nature reserve of tidal flat and wet land in China.

盐城国家级珍禽自然保护区是我国最大的沿海滩涂湿地自然保护区。

10·The northern Yellow Sea muddy coast changes, the formation of coastal landform and the natural zoning of tidal flat are analysed.

分析了冰后期以来北黄海淤泥质海岸变迁及海岸地貌的形成和滩涂的自然分带。
