In China, on one hand, villagers income was rising. On the other hand, the environment was running down gradually: In 2009, pesticides were used by 89% of farmers. Upon 300,000 tons of pesticides were used in the whole country annually. And 60～70% of pesticides were dissolved in waters and soils;67% of daily rubbishes were discarded arbitrarily by villagers in country;74% of farmers made use of plastic film, while only 13% of it was cleared completely;the decrease of forest areas that due to the denudation was almost 50% compared with the last 5 years;in villages, many resources were not effectively used. 64% of the villagers did not re-use waste consciously. It can be concluded that protection of the ecological environment in rural areas was urgent. As a sample writer took an investigation in a village.
