Address by Vice Prime Minister Tian Jiyun in the Fifth National Soil and Water Conservation Conference
Within 10 years after the forth national soil and water conservation conference held in 1983, soil conserva-tion works were carried out in more than 9000 small watersheds, with a total area of 400, 000 km2, 200, 000 km2 of which were comprehensively controlled and 530, 000 km2 has been harnessed accumulatively. Simultaneously 180, 000 km2 of defense forest was built. The extant soil conservation facilifies may increase 18 billion m3 water-conserving capacity annually and reduce soil errosion by 1. 1 billion tons, which has ob-vious effect in improving ecological environment and promoting the economic development in mountainous areas. Two-thirds of total area in China is mountainous area with serious soil errosiorn. More than one bil-lion km2 area which subjects to water errosion has not been harnessed until now and soil loss tends to expand in some regions. The harnessment work is still very difficult. Comprehensive management and maintaince and harnessment in key areas are the general goal and task for soil and water conservation works in the coming ten years. Prevention, supervision and managment should be given priority in the soil conservation work. Soil conservation will be continuously stressed for 14 major control regions, especially for the middle and upper basins of the Yellow River, Yangtze River above the Three Gorges project. The soil conservation work will be gradually spread by seriously implementing the law of soil and water conservation, increasing the input through various channels and combining harnessment with exploitation.
