| Abstract: | The total area of soil erosion, which is 51.2% of the national region, is 4.92 million km 2 in China, The economic development and social stability is heavily influenced by the erosion. This paper analyses the formative factors and damage of soil erosion. All the damage includes damaging land resources, decreasing cereal production, inducing natural disaster, reducing soil fertility, polluting water enviroment, causing lakes and reservoir deposited and menacing cities et al. Overall, soil erosion is the key factor to damage ecosystem. With the conclusion above, it's useful for the government to prepare the best measures to prevent the erosion and reduce its damage. |
