1. 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.

2. Topographic factors such as hypsography and earth curvature are greatly responsible for remote sensing image distortion.

3. There are good ecological environment and view around, the high hypsography make the ventilation and drainage well.

4. Side-scan sonar is an important means of detection in hypsography, and its incorporation of computer technology has greatly promoted its development.

5. The consequence demonstrates that DEMs of different grid size should be adopted according as the hypsography when model parameters are confirmed by the topographic characteristics.

6. And the soil loss of the grading terrace is more serious than the paddy field, with lower hypsography .

7. 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.

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

9. 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.
