   Yangtze basin is one of the most serious area of 鈥嬧€媠oil erosion, soil erosion area of 鈥嬧€?85,000 square kilometers, accounting for 21% of the total area of 鈥嬧€媡he basin. Since 2000, the Yangtze River Basin soil erosion control effectiveness significantly, control soil erosion area of 鈥嬧€?45,000 square kilometers, the deterioration of soil erosion has been effectively curbed.

   It is reported that soil erosion is mainly distributed in the middle reaches of the cloud , Guizhou, Sichuan and other seven provinces, particularly in western Sichuan, southwestern rocky areas, Qinba mountains, Wuling mountainous areas and old revolutionary base areas and other centralized distribution of more than 200 state-level poverty-stricken counties, soil erosion prevention and control of these areas is very task difficult.

   contradiction between development and protection of the Yangtze River has become increasingly prominent

   responsible person pointed out that with rapid economic and social development, the contradiction between development and protection of the Yangtze River basin are also increasingly prominent, water ecology situation is not optimistic . Mainly in waste water discharge volume is still high, some of the river water quality is not up to the heavier part of the lake and reservoir eutrophication, water pollution incidents are a big risk, lakes, wetlands shrinking phenomenon still exists.

   water resources management and environmental protection work should pay attention to

   The official told reporters that the face of this situation, to implement the most stringent water management system and environmental protection system, strengthen water resources carrying capacity rigid constraints, gradually break down the most stringent water management "three red lines" control targets, reasonably determine the size of the regional economy, urban layout and industrial structure. To strengthen the planning and construction of major water resources demonstration projects, strictly control the development of high water consumption industries, strict control of new areas along the Yangtze River water intake, promote conservation and waste reduction.

   Meanwhile, enhanced water environment carrying capacity rigid constraints. Protection of water resources, improve water environment, the key is to strengthen pollution control, control the amount of pollutants discharged into rivers. According to the water quality objectives water functional area requirements, reasonably determine the pollutant limits to control the red line, strengthen supervision and management of the sewage outfall into the river, and strengthen the important drinking water source protection. Strive to 2020, to improve the water quality compliance rate of important functional areas to more than 84%, eutrophication of lakes and reservoirs has been effectively controlled.

   "in strengthening the ecological carrying capacity of the rigid constraints of water, according to the Yangtze River Basin Integrated PlanningDetermine the ecological protection and control red line, involving the core area of 鈥嬧€媙ature reserves, river ecologically sensitive areas, prohibit large-scale development and construction activities. River section according lake ecosystems ecological water demand and level control requirements to ensure ecological water lakes, river and lake water to enhance circulation of the water, maintain good ecological system. "The official said.

   According to the person in charge, in the Grand River conservation efforts, continue to adhere to prevention, focused, partition prevention approach, comprehensive Accelerating erosion control, and strive to 2020 new area of 鈥嬧€?28,600 square kilometers of soil erosion, and soil erosion prevention and treatment of human law, to increase the area of 鈥嬧€媏cological protection of the Yangtze River, the Three Gorges Reservoir water Conservation District and other countries strictly control the construction of key projects along the river-intensive areas, strengthen the focus on engineering and production construction project supervision and management, strictly implement soil and water conservation, "three simultaneous" system, and increase penalties for violations of building a beautiful sky blue green beautiful Yangtze River.
