The area of Yichang soil and water conservation major region of upper reaches of the Yangtze rive area totals 8372km2

of which the area of soil erosion is 4 710.22 km2

accounts for 56.26%. The area of middle mountain accounts for 89.1%

the area of steep slop (>25) accounts for 68.35%. The amount of precipitation of flood season accounts for 70.25% of annual rainfall. Besides collapse and landslide disasters are frequency

and Three Gorges project will expropriate and irrigate 100.5 km2 of land area of three county

the sum of migrants is about 0.136 million. So anthropogenic soil and water loss become more serious. We should firmly seize the opportunities of "Yangtze treatment project implementing"

make terrace on slop and establish production forest projects and take them as a breakthrough

implement the comprehensive measures to optimize the structure and shaped the pattern of strip transect and block. We developed soil and water conversation integrative protection system while optimized the land structure of utilization and the pattern of agriculture

and we have essentially controlled the soil and water loss. Now

the annual runoff volume has been reduced

the annual soil erosion amount has been reduced 5.22 million tons and increased settlement of 37 per km2. Through the increasing development of characteristic prop industry of orange and tea

we have accelerated the sustainable socioeconomic development.
