I go to low - lying coastal areas for the study of hypsography.

我为研究地势去低洼海岸线地区。

The landscape is special because it's mountainous area land surface is incised fiercely and hypsography has great disparity.

山地多，地表切割强烈，地势悬殊大，自然风光独具特色。

This item is chosen to locate in the east of Wenan town, with complanate hypsography, complete water and electricity supply, without contaminated, meet the requirements of item location.

本项目选址在文安县城东，地势平坦、水电齐全、无环境污染，符合项目选址要求。

The mountainous area accounts for 94% in Yaan. There is a great difference in the height of hypsography, and stream is rapid, and the tectonics cross the west geosyncline and east platform.

雅安山地面积占94%，地势高低悬殊大，河流深切，水流湍急，大地构造位置跨西部地槽，东部地台。

Aiming at the error in intense hypsography terrain area statistic, the paper puts forward an improved statistic method for intense hypsography terrain, and introduces their application fields.

针对强起伏区面积统计误差，提出一种地形强烈起伏区的面积统计误差的改进方法，并扼要说明它们的一些应用领域。
