In the area of watershed between the Yangtze River and the Huaihe River

there are a series of ecological environmental issues

such as fragile forest ecosystem

frequent drought damage

lake of water resources

serious soil and water loss and contamination by chemical fertilizer

pesticide and plastic membrane.The main causes resulting in the ecological issues were analyzed in terms of geological conditions

climate factors

forest coverage and soil conditions.According to natural conditions of the area natural rules and systematic engineering principle

a series of countermeasures were propased such as improving forest cover degree

enhancing water conservancy project

adjusting agricultural production constitution

combining engineering measures with ecological measures to restore mine ecosystem and to take comprehensive measures to control soil erosion so as to improve ecological environmental quality in watershed between the Yangtze River and the Huaihe River.
