In the case of Desertification, this specific positive feedback loop involves "land degradation processes (e.g., nutrient loss or salinization), changes in rainfallregimeresulting from land-atmosphere interactions (e.g., precipitation recycling, dust emissions), or changes in plant community compositio...
In the final analysis, when viewed in the national perspective, the effects on agriculture are the most troublesome aspect of desertification in the US. For it comes at a time when we are losing over a million acres of rain-watered crop and grass land per year to higher uses―shopping ...

showed regional differences.The increase of population density is not a key factor limiting the growth of vegetation;the policy of"grazing prohibition,grazing rest,and rotational grazing"has allowed the restoration of vegetation;and afforestation is an effective way to promote the increase in FVC. ...

The Mu Us Sandy Land is located in the middle of the farming pastoral ecotone of northern China. The direction of the development of desertification has a direct impact on the economy and development of the northern region. Six remote sensing images acqu
Passage 1Desertification is a serious problem 1 (face) numerous countries in the world. Shi Guangyin, an eco-warrior from Shaanxi Province, 2 (battle) desertification for over 40 years. Born in a town on the southern edge of the Mu Us Desert, Shi remembers how sandstorms easily destroyed th...
【题目】7DesertificationDesertification is one of the world's most alarming processes of environmentaldegradation (退化). The issue is often unclear, however, by a common misperception: thatit's a “natural” problem of advancing deserts in faraway developing countries. In fact,desertfication is ...
The family has turned 30km^{2-}of desert into woods. These trees have made a big difference.With continuing efforts, the Mu Us Desert will be gone. In Yulin, the number of sandy days has dropped from 100 in 2000 to 10 now. It has changed from "looking for green in the sand" in...
