Program and Benefits on Controlling Weathereds in Disintegration Granite Area in Deqing County of Guangdong Province

The area of granite occupies 67.3% of totalland area in Deqing county of Guangdong province. Due to artificial and natural factors,this county has the most serious disintegration in Guangdong province. Based on thecontributing factors, types and features of the disintegration, the guiding principles ofdisintegration control are to apply the coordination of engineering and biologicalmeasures, which is to use engineering techniques to arrest the immediate loss of soil, andto develop re-vegetation programs for long-term stabilization of the slopes. Greatbenefits of society, ecology and economy have been attained after it has been controlledsince 1949, but the soil erosion (especially disintegration) is still very serious.Therefore, it must be controlled permanently. At the same time, some feasible proposalsare presented for its controlling.
