负地形

红粘上相对集中地分布在地表岩溶地貌的负地形上，多发育于地形舒缓的剥蚀夷平台地及波状起伏的岩溶盆地。

Red clay is always concentrating distribution at negative relief of karst landform , such as flat denudation-leveling terrace and undulate karstic basin .

该方案根据现实可得DEM数据的精度，指出DEM中“数字负地形”来自真实的地形和伪地形；

According to current DEM resolution , depressions and flat areas in a DEM are mainly from real landform features and spurious features .

斑岩体靠沟谷部位（负地形）等。

The porphyry body close to a valley ( negative landform ), etc.

存在明显的负地形。

And 3 there exists a obviously concave landform .

自然地貌主要选取水系负地形和地貌形态指标来量化。

About natural geomorphology , I mainly choose indexes of river system and ground shape .

谱模式中负地形的处理与东亚副热带气候的模拟

Disposal of Negative Orography in a Spectral Model and Modeling of Subtropical Climate in East Asia

这与低分辨率谱模式中存在负地形有关。

This is found to result from the existence of negative orography in this low-resolution model .

黔中一带早石炭世准溶原面上，发育大量岩溶负地形，诸如溶盆、溶洼等。

In Early Carboniferous karst peneplain of Central Guizhou there were a lot of karst negative forms , for example karst basin , karst depression .

本文通过理论分析指出，在负地形的格点上，出现了虚假的感热热源，导致其上空温度偏暖，高度偏高。

It is shown that , over the grid-points where orography height is negative , there exists false sensible heat source that leads to warmer temperature and higher geopotential height .
